Detailed documentation about all features and settings of CFF.
From the dashboard/configuration area the process is as follows:
From the end user (visitor) point of view, the process is as follows:
To install the WordPress plugin follow these steps:
Using the WordPress Classic Editor
Using the Gutenberg Editor
Using Elementor
Using Page Builder by SiteOrigin
Using Beaver Builder
Using DIVI Builder
The "CFF" is completely functional even without be registered. But after registering the plugin, the updates are received directly into WordPress.
For registering the plugin follows the steps below:
After registering the plugin the updates are notified in the "Updates" section of WordPress.
After going to the WordPress administration menu >> Settings >> Calculated Fields Form you will see the list of forms like in the following image:
For each form you will see the following options:
After clicking the "Settings" button you will jump to a new page with the form builder a other configuration options as explained below.
Press the "Messages" button, corresponding to the form. The messages screen displays the list of submissions, and a filtering section to reduce the submissions by form, a time interval, or a text in the data
From the messages screen it is possible remove a submission, or submissions group, change its status to paid/unpaid, editing the entry data, but from this screen is possible export all submissions to a CSV file
For editing the information associated to an entry in the list press the corresponding "Edit" button. The action will load a form with the fields in raw mode, not associated to the form's structure, to modify them freely.
For exporting the submitted information to a CSV file, press the "Messages" button corresponding to the form, and press the "Export to CSV" button, select the location where will be saved the CSV and that's all. The first row of CSV file allows identify each of fields, the text used to identify the field will be the short label, defined in the field, or the label in case that the short label is not defined.
The "Calculated Fields Form" allows exporting the forms created in a WordPress website to be imported in other websites(*). The feature is really thankfully for owners or developers of multiple websites to avoid implementing the same form once and once again.
Note(*): Both websites must be using the same version of the plugin to have a compatible exported file.
To export a form:
To import a form:
The new form will appear in the list of forms. To modify it use the related "Settings" button.
The Form Builder lets you to add/edit/remove fields into the form and also to specify the validation rules for your form (required fields, email fields, etc...).
The "Form Settings" tab allows define the form's title and description, as the placement of labels with respect the fields (at top, at left, aligned to the right).
In the "Form Settings" tab is possible to enable the autocompletion of fields, evaluate dynamically the equations (or evaluate the equations through a "Calculate" button). In case of evaluate the equations dynamically it is possible configure the form to evaluate the equations in the onchange events, or in the onchange and keyup events.
Furthermore in the forms settings tab it is possible configure the form's design. The plugin includes multiple predefined designs.
If the browser's persistence option is ticked the plugin will store the data entered by the users, locally in their browsers (only compatible with the browsers with support for the localStorage object) until the form be submitted. So, if an user that is filling the form closes the tab, the next time the user visit the webpage the form's fields will be prefilled with the data stored in his browser.
Through the "Customize Form Design" attribute in the "Form Settings" tab, it is possile to enter the CSS rules to apply to the form and customize its appearance. The list of class applied to the different fields and section of forms is available in the FAQ entry: How can I apply CSS styles to the form fields?
The form builder includes some container controls. The container controls allow to insert another controls in them:
Developer Version Platinum Version
In addition to the above, the following fields are available only in the Developer and Platinum versions of the plugin:
When you click a field already added, you can edit its details and validation rules. The following properties are useful:
When clicking over a calculated field in the form builder the following settings will appear:
In addition to the general fields settings there are three additional settings:
If you are implementing a complex equation, you can press the "ADVANCED EQUATION'S EDITOR" button in the field's settings, to load a javascript editor with auto-completion, colors code for reserved words, errors detection and more:
Note for advanced users: The JavaScript ternary operator is also supported: (condition ? value_if_true : value_if_false). See the "Ideal Weight Calculator" for a sample.

This is a step by step about the use of datasource controls
There are different datasources: MySQL Database, CSV file, Recordset, Post Type, Taxonomy, and User Data.
Note: Depending of control selected will be available all available datasources, or not.
So, suppose we want populate the field with the data stored in a database table.
Note: If the database is the same used by WordPress, leave empty the fields above.
Now its time to define the query to database
If your query is very complex, and you prefer create it manually; selects the option "Custom Query", but in this case you should type all the query. Pay attention because you should use alias in the "SELECT" clause, to indicate the colum used to get the values, and the column used to get the texts. For example, a hypothetical query:
SELECT column1 AS value, column2 AS text FROM tablename WHERE column3 > 5 ORDER BY column2 ASC LIMIT 5
The use of database as datasource, allows filtering the information to populate the fields with the values on other fields in the form, or javascript variable. The use of variables are only accepted in the "Condition" section ("WHERE" clause), and requires the format: <%varname%>. For example, to get the title of a post, filtering by its ID, if the id is defined through the fieldname3 field, the "Condition" attribute of the query would be: ID=<%fieldname3%>
Besides the variables, the plugin allows the use of some constants in the queries. The constants must be enclosed between curly brackets, for example: {user.id}
Assuming you want to insert a "DropDown DS" field where the texts of the choices are the posts' titles, and the values of choices are their IDs, but only for the posts belonging to the logged user, in this case the query to associate with the "DropDown DS" field would be:
SELECT ID as value, post_title as text FROM {wpdb.posts} WHERE post_author={user.id}
In the previous query the constants: wpdb.posts corresponds to the name of the posts table in your WordPress, and user.id to the id of logged user.
The complete list of constants:
blog.id, the id of the current blog (useful in multisite WordPress installations)
wpdb.prefix, prefix used by WordPress in the name of database's tables, for example, the text "wp_" into the table's name "wp_posts"
wpdb.comments, the name of Comments table
wpdb.commentmeta, the name of Comment Metadata table
wpdb.links, the name of Links table
wpdb.options, the name of Options table
wpdb.postmeta, the name of Post Metadata table
wpdb.posts, the name of Posts table
wpdb.terms, the name of Terms table
wpdb.term_relationships, the name of Term Relationships table
wpdb.term_taxonomy, the name of Term Taxonomy table
wpdb.termmeta, the name of Term Meta table
wpdb.usermeta, name of User Metadata table
wpdb.users, the name of Users table
wpdb.blogs, the name of Multisite Blogs table
wpdb.blog_versions, the name of Multisite Blog Versions table
wpdb.site, the name of Multisite Sites table
wpdb.sitecategories, the name of Multisite Sitewide Terms table
wpdb.sitemeta, the name of Multisite Site Metadata table
user.id, the id of the current user
user.login, the username of the current user
user.nicename, the URL-friendly name for the current user
user.email, the email address of the current user
user.url, the URL associated to the current user
user.display_name, the user's name that is shown on the site for the current user
user.first_name, the first name of current user
user.last_name, the last name of current user
The CSV files can be used as data sources for fields with multiple choices (DropDown DS, Radio Btns DS, Checkboxes DS). The initial steps are similar to the previous section, but selecting the "CSV" option as data-source instead of selecting "Database".
A comma-separated values (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format.
For CSV files, the plugin includes the attributes:
Select CSV file: allows to select between a local or online file. For local files, the field displays a file field for selecting the CSV file. For online files the field displays a text field for entering the URL to the CSV file.
Use headline: tick the checkbox if the first line of CSV file is a headline to identify the data in the next records.
Delimiter: enter the delimiter symbol used as the field separator on each record.
Press the "Import CSV" button to import the records into the form. This action will feed the lists "Select column for texts" and "Select column for values", that are used for selecting which fields will be used texts and values of the choices in the DS field.
Where the value is equal to: allows filtering the rows to include in the field. The value entered in the attribute must be equal to the value in the column selected for the field's values. It is possible to use the values in other fields in the form, or variables, for filtering the rows, similar to the "Database" datasource.
Enter the conditions for filtering.
This clause require additional instructions, that are explained with an example:
Assuming the values in the "RecordSet DS" fields, selected as datasource, is a list of records with the structure:
{
'First Name' : 'John',
'Last Name' : 'Smith',
'Birth Date' : '1th Jan, 2001'
}
and you want populate a "Line Text DS" field with the "Birth Name" of the user "John Smith"
Type the property name: Birth Date in the "value" attribute.
Enter the properties for filtering in the condition field (pay attention to the use of the reserved word "record" in the conditions):
record['First Name']=='John'&&record['Last Name']=='Smith'
Tips: Javascript is casesensitive, please, be careful with the properties names.
In the conditions can be used the following comparison operators:
equal to: ==
non equal to: !=
less than: <
less than or equal to: <=
bigger than: >=
bigger than or equal to: >=
And the logical operators:
and: &&
or: ||
Some fields, like radio groups, checkboxes and drop-down menu, allow dependencies in function to the option selected.
For example, suppose your form includes a radio-group control with multiple choices: - House, - Car, - Electrodomestics, and each of them, uses different attributes. The house requires fields for address, number of rooms, etc; the car requires a field for trademark, model, etc. and finally the electrodomestics, will need type of electrodomestic,and more. So, if you want display the fields, depending of choice selected:
The calculated fields allow dependencies too, but in function to its value. For example, if you are designing a form for selling electrodomestics, and you want display additional fields for finance the purchase, if the amount is bigger than or equal to $1000usd. In this case:
Create dependencies with other fields. It is possible create dependencies with Dropdown fields, checkboxes, radio buttons, and calculated fields. To define dependencies with other fields, would be necessary to use Calculated Fields as auxiliary fields. Simply, should to use the field as part of the equation associated with the calculated field, and create dependencies rules in function to the equation's result. The auxiliary fields are not relevant in the form's interface, to hide them, tick the checkbox: "Hide Field From Public Page"
For each form you will be able to edit the following settings:
Form Builder: Already explained in the previous sections (see above).

It is strongly recommended the use of an email address in the website's domain. The main emails services (as Gmail, Hotmail, Yahoo, MSN, etc.) check the correspondence between the email address in the "Sender" header on emails, and the domains that send the emails. If the correspondence fails, the emails can be managed as Spam or as a "Phishing" email, in whose case would be deleted for security reasons.

The shortcode to insert in the thanks page allows a total control over the content to display with it.
In case to display all fields submitted with the form, is as simple as insert the shortcode: [CP_CALCULATED_FIELDS_RESULT]. But what to do if you want include in the thanks page only some of submitted fields, and not all?
The shortcode allows define the "fields" attribute, to select the fields names to include in the thanks page, separated by the comma symbol. For example, suppose the form has three fields: fieldname1, fieldname2, and fieldname3, but we want include only the fieldname1, and fieldname3, and exclude the fieldname2, in this case the shortcode would be:
[CP_CALCULATED_FIELDS_RESULT fields="fieldname1,fieldname3"]
But in some cases, we need more control over the content to display. By default, the shortcode is replaced by pairs of label-value for each field included in the thanks page. But what happen if you want display the label of fieldname1 in bold, or use a different label for the fieldname2, that the label used in the form?. In this case you should use the shortcode like a tag: [CP_CALCULATED_FIELDS_RESULT]...[/CP_CALCULATED_FIELDS_RESULT], and its content would be common HTML tags, with the field names using the same format that in the notification emails: <%fieldname#%>, to display only the label <%fieldname#_label%>, and to display only the value <%fieldname#_value%>. So, in this case the shortcode would be:
[CP_CALCULATED_FIELDS_RESULT]
<p><%fieldname1_label%>:<%fieldname1_value%></p>
<p>New Label: <%fieldname2_value%></p>
<p><%fieldname3%></p>
[/CP_CALCULATED_FIELDS_RESULT]To get the complete list of tags to include in the thank you page, read the "SPECIAL TAGS IN THE NOTIFICATION EMAILS" section .
The shortcode accepts too the if_latest attribute, whose accepted values are: 0 or 1 (0 by default) to replace the shortcode, only if it corresponds to the latest submitted form. This attribute should be used in combination with the formid attribute described in the next section.
[CP_CALCULATED_FIELDS_RESULT formid="3" if_latest="1"]
The forms' structures can be very different, and an unique shortcode wouldn't be sufficient to represent all forms. An option would be insert a different summary shortcode for each form, defining the attribute: "formid" indicating the form's id, in each of shortcodes, in whose case the plugin will replace only the shortcode corresponding to the form that has been submitted:
[CP_CALCULATED_FIELDS_RESULT fields="fieldname1,fieldname3" formid="1"]
[CP_CALCULATED_FIELDS_RESULT fields="fieldname8,fieldname9,fieldname14" formid="2"]
[CP_CALCULATED_FIELDS_RESULT formid="4"]
[CP_CALCULATED_FIELDS_RESULT formid="5"] <p><%fieldname1_label%>:<%fieldname1_value%></p> <p>New Label: <%fieldname2_value%></p> <p><%fieldname3%></p> [/CP_CALCULATED_FIELDS_RESULT]
Professional Version Developer Version Platinum Version
This shortcode is similar to [CP_CALCULATED_FIELDS_RESULT]. With this shortcode it is possible to display all submitted fields or controlling the fields and format of the summary.
However the [CP_CALCULATED_FIELDS_RESULT_LIST] requires the formid attribute with the form's id. For example: [CP_CALCULATED_FIELDS_RESULT_LIST formid="1"]
Or at least a submission's id: [CP_CALCULATED_FIELDS_RESULT_LIST submission="123"]
There are other attributes supported by the [CP_CALCULATED_FIELDS_RESULT_LIST] shortcode, but these are optional:
For controlling the format of submissions' summaries it is possible to insert the shortcodes with a content, similar to:
[CP_CALCULATED_FIELDS_RESULT_LIST formid="1"]
<p><%fieldname1_label%>:<%fieldname1_value%></p>
<p>New Label: <%fieldname2_value%></p>
<p><%fieldname3%></p>
[/CP_CALCULATED_FIELDS_RESULT_LIST]The complete list of tags to include in the shortcode is avalialbe in the "SPECIAL TAGS IN THE NOTIFICATION EMAILS" section .
All Versions of the Plugin
The icon with the "X" symbol, that appears when editing the contents of pages or posts, inserts a shortcode in the content with the structure:
[CP_CALCULATED_FIELDS_VAR name="..."]
The ... symbol should be replaced by the parameter or variable name, and will be the same name of the javascript variable. For example: [CP_CALCULATED_FIELDS_VAR name="varname"]
To restrict the source of variable, define the attribute "from" in the shortcode with any of following values: get, post, session, or cookie. For example, to create the javascript variable: varname, only if exist a session variable with the same name, insert the shortcode: [CP_CALCULATED_FIELDS_VAR name="varname" from="session"]
The shortcode: [CP_CALCULATED_FIELDS_VAR] accepts two other attributes:
The "default_value" attribute allows to define the value used by default if there is not a parameter with the specified name, or session variable or cookie:
[CP_CALCULATED_FIELDS_VAR name="varname" default_value="mydefault"]
If there is not a parameter, or session variable, or cookie, with the name "varname", the plugin will create a global javascript variable with the name: "varname", and value: "mydefault".
The attribute: "value", allows to create a javascript variable with the name defined as attribute, and the value in the attribute: "value".
[CP_CALCULATED_FIELDS_VAR name="varname" value="myvalue"]
After insert the shortcode to create the javascript variable, a valid equation would be: fieldname1*varname
There is another way to create global variables to be used in the equations, directly from the form's shortcode. All attributes in the shortcode, except the "id" that identifies the form, are converted in javascript variables with global scope, whose names correspond to the variable name, and their values, the attributes' values:
[CP_CALCULATED_FIELDS id="1" varname="varvalue"]
It is possible create multiple variables, defining multiple attributes.
The variables created through the form's shortcode have a particularity, for each global variable will be created another one with the structure: <variable name>_arr, for example: if the shortcode is:
[CP_CALCULATED_FIELDS id="1" varname="varvalue"]
The plugin will create two varaibles, the global variable: varname whose value would be varvalue, and the varname_arr variable, whose value is a hash with the varvalue as one of their items.
How to access to the value of the varname_arr?
Simply should be called the varname_arr variable, using as the index, the form_identifier constant: fieldname1*varname_arr[ form_identifier]
Pay attention to this way to access to the variables generated through the form shortcode. If there are multiple shortcodes inserted in the same page, and all of them define a same variable, accessing to the variable name through the scheme: <variable name>_arr[ form_identifier], each form will have its own value for the variable, because the global variable <variable name> will have only the latest value defined.
The list of add-ons available in the plugin, appear in the "Add-ons area" of settings page of the plugin. For enabling the add-ons, simply should tick the corresponding checkboxes, and press the "Activate/Deactivate Addons" button.
Developer Version Platinum Version
The Server Side Equations add-on allows to define equations in the server side to protect the business logic, and call them with AJAX from the public form.
The server side equations are defined from the settings page of the plugin, through the "Server Side Equations section".
The server side equations are shared by all forms in the website, reducing the development time.
The server side equations are implemented with PHP programming language. The equations should be entered below the line of comment: INCLUDE YOUR CODE FROM HERE.
The equations should be defined into the GLOBAL array: "SERVER_SIDE_EQUATIONS", where the items' indexes are the names of the equations, and the items values are functions definitions with the code of the equations.
For example, assuming you want to implement an equation that calculate the square root of a number, a possible equation would be:
$GLOBALS['SERVER_SIDE_EQUATIONS']['square_root_equation'] = function($number){return sqrt($number);};
The add-on includes a new operations module with the operation: SERVER_SIDE for calling the server side equations using AJAX.
The "SERVER_SIDE" operation requires at least one parameter, the name of the server side equation (following with the previous example, the first parameter would be: 'square_root_equation') and the other parameters would be the parameters required by the server side equation.
SERVER_SIDE('square_root_equations',4)
the result would be 2
To get the square root of a field in the form, for example, the fieldname1, the equation would be:
SERVER_SIDE('square_root_equations',fieldname1)
The Server Side Equations add-on includes a new section in the form's settings to allow calculate the final price through a server side equation, after the form be submitted.
To calculated the final price with a server side equation:
Tick the checkbox: "Evaluate the final cost with a server side equation, once the form be submitted"
Enter the server side equation call with the format: equation_name(fieldname1, fieldname2, fieldname3)
Developer Version Platinum Version
The new add-on: "Users Permissions", allows restrict the access to the forms, and associate the submitted information to the submitter.
The options to restrict the access to the form are: Only for registered users, for registered users with specific roles, or allow the access to the form only to specific users.
With the "Users Permissions" add-on it is possible restrict the number of submissions to only one by user.
The add-on includes a new shortcode: [CP_CALCULATED_FIELDS_USER_SUBMISSIONS_LIST], to display the list of submissions belonging to an user. If the shortcode is inserted without attributes, the list of submissions will include those entries associated to the logged user. This shortcode accepts the attributes: id, for the user's id, and login, for the username (the id attribute has precedence over the login), in whose case the addon will list the submissions of the user selected, furthermore it is possible restrict the list to a specific form using the attribute: formid="#", where # should be replaced by the form's id. Additionally, it is possible to decide the number of items per page (10 by default), defining the "events_per_page" attribute through the shortcode, ex: [CP_CALCULATED_FIELDS_USER_SUBMISSIONS_LIST events_per_page="20"]
The add-on allows to define the summary of the submitted data that will displayed in the list of submissions. Enter the summary's structure in the "Summary" attribute. In the summary can be use all the special tags, available for the notification emails, and the thank you pages.
Note, that it is possible to define the structure of data directly through the shortcode, and this takes precedence over the "Summary" attribute. Ex:
[CP_CALCULATED_FIELDS_USER_SUBMISSIONS_LIST]
<p><b><%fieldname1_label%></b>: <i><%fieldname1_value%></i></p>
[/CP_CALCULATED_FIELDS_USER_SUBMISSIONS_LIST]
The add-on allows to assign permissions for "edit" or "delete" the entries. Actually, the submissions are not deleted, or its data modified from these actions, the real control over the data is only for the website's administrator. In the first case, the submission will be disabled, and will be hidden from the list of user's submissions, but the submission is always accessed by the website administrator through the messages section, and if the data are edited, the original entry will be disabled, and a new entry is generated and associated to the user.
There are other features included by this add-on, the "Messages" section is modified to include in the list of submissions the name of the submitter, furthermore, includes a new input field for filtering the events by users.

To calculate the monthly payment in a lease calculator:
The fields implied are:
Load amount: fieldname1
Residual value: fieldname2
Interest rate %: fieldname3
Number of months: fieldname4
The corresponding equation for monthly payment is:
prec((fieldname1*fieldname3/1200*pow(1+fieldname3/1200,fieldname4)-fieldname2*fieldname3/1200)/(pow(1+fieldname3/1200,fieldname8)-1),2)
There is a huge number of equations that can't be recreated with simple mathematical operators, or the operations listed above.
| Operation | Description | Demo |
|---|---|---|
Pay attention to the following sample:
In your form there are four fields: fieldname1, fieldname2, fieldname3 and the calculated field: fieldname4, but the value of fieldname4 is dependent of fieldname3 value, that is:
The value of fieldname4 will be: fieldname1+fieldname2, if the value of fieldname3 is greater than 100, or will be: fieldname1*fieldname2, if the value of fieldname3 is less than or equal to 100. Neither of previous operations, by itself, can calculate the value of fieldname4.
To solve complex cases like this, the "Calculated Fields Form" plugin allows entering javascript code directly in the equation editor, like the following sample:
(function(){
if(fieldname3 > 100) return fieldname1+fieldname2;
if(fieldname3 <= 100) return fieldname1*fieldname2;
})();
For complex equations where is required to define blocks of javascript code, you must use the following format:
(function(){
//Your code here
})();
and the return the value of that function will be the value assigned to the calculated field:
return fieldname1+fieldname2;
Pay attention, the plugin removes the changes of lines from the equations at runtime. So, if the equation is defined with the "function" format:
(function(){
//Your code here
})();
It is really important to include the semicolon symbols (;) at the end of the code lines, furthermore, if the equation is really complex, and you want to include comments for future references, should be used the format for multiple lines comments: /* comment here */, but never the format for single line of comments: // comment here
All Versions of the Plugin
The logical module include the following functions:
| Function | Description | Demo |
|---|---|---|
| IF(condition, value if true, value if false) | Checks whether a condition is met, and returns one value if true, and another if false.IF(logical_test, value_if_true, value_if_false) | If the value of fieldname1 is 10 and the value of fieldname2 is 20, the result of: IF(fieldname1 < fieldname2, fieldname1, fieldname2) |
| AND(x,y,z,....) | Checks whether all arguments are true, and return true if all values are true, and false in another way. AND(logical1,logical2,...) | Suppose there are three fields, fieldname1, fieldname2 and fieldname3, with values: 10, 20 and 30 respectively, so: AND( fieldname1<100, fieldname2<100, fieldname3<100) but AND( fieldname1<100, fieldname2<100, fieldname3<25) |
| OR(x,y,z,....) | Checks whether any of arguments is true, and return true if any of values is true, and false if all values are false. OR(logical1,logical2,...) | Suppose there are three fields, fieldname1, fieldname2 and fieldname3, with values: 10, 20 and 30 respectively, so: OR( fieldname1<100, fieldname2<100, fieldname3<25) but OR( fieldname1<5, fieldname2<5, fieldname3<25) |
| NOT(x) | Changes false to true, or true to false.NOT(logical) | NOT(true) NOT(false) |
| IN(x,[x,y,z,....]) | Checks whether the term is included in the second argument, the second argument may be a string or strings array. IN(term, string/array) | IN(10,[10,20,30,40]) IN('world', 'hello world') |
Developer Version Platinum Version
The module includes a pack of functions to improve the implementation of financial equations. Distributed with the Developer or Platinum versions of the plugin.
The CALCULATEAMORTIZATION is the operation with most complexity in the "Calculated Fields Form" and requires its own section.
The CALCULATEAMORTIZATION operation returns a list of objects. For example:
CALCULATEAMORTIZATION(25000, 60, 5.25, new Date(2011,11,20) )
Result: [ { principle: 24634.725 interest: 109.375 payment: 474.65 paymentToPrinciple: 365.275 paymentToInterest: 109.375 date: Tue Dec 20 2011 00:00:00 GMT+0100 (Romance Daylight Time) }, { principle: 24267.851921874997 interest: 217.151921875 payment: 474.65 paymentToPrinciple: 366.873078125 paymentToInterest: 107.776921875 date: Fri Jan 20 2012 00:00:00 GMT+0100 (Romance Daylight Time) }, ... ]
In the following example, we explain the use of the CALCULATEAMORTIZATION operation: the fieldname1 represents the principle amount, fieldname3 the number of months, and the fieldname2 the interest rate.
So, the value returned by CALCULATEAMORTIZATION(fieldname1,fieldname3,fieldname2) cannot by assigned directly to the calculated field, or will be displayed a text like: [object],[object],...... Therefore, we'll need to create a formatted string, with HTML tags, to display the CALCULATEAMORTIZATION results in an understandable format.
(function(){
var r = CALCULATEAMORTIZATION(fieldname1,fieldname3,fieldname2),
str = '';
if(r.length)
{
str = '<table cellpadding=" 10" >';
str += '<tr>';
str += '<td>Date</td>';
str += '<td>Interest</td>';
str += '<td>Payment</td>';
str += '<td>Payment to Interest</td>';
str += '<td>Payment to Principle</td>';
str += '<td>Principle</td>';
str += '</tr>';
for(var i = 0, h = r.length; i < h; i++)
{
str += '<tr>';
str += '<td>'+GETDATETIMESTRING( new Date(r[i]['date']), 'yyyy-mm-dd')+'</td>';
str += '<td>'+PREC(r[i]['interest'],2)+'</td>';
str += '<td>'+PREC(r[i]['payment'],2)+'</td>';
str += '<td>'+PREC(r[i]['paymentToInterest'],2)+'</td>';
str += '<td>'+PREC(r[i]['paymentToPrinciple'],2)+'</td>';
str += '<td>'+PREC(r[i]['principle'],2)+'</td>';
str += '</tr>';
}
str += '</table>';
}
jQuery('.comment_area .uh').html( str );
})()
The first step will be store the list of objects returned by the CALCULATEAMORTIZATION operation, in a local variable, and create another variable to store the amortization data, but with an HTML format:
var r = CALCULATEAMORTIZATION(fieldname1,fieldname3,fieldname2), str = '';
The equation validates if the previous operation returns a value, because if the CALCULATEAMORTIZATION was called with wrong values can return an empty array:
if(r.length)
{
...
}
I've decided display the results of CALCULATEAMORTIZATION operation in a tabular format because is easier to understand. The first element in the result is the tag to open the table: <table>, and the row with the column names:
str = '<table cellpadding=" 10" >'; str += '<tr>'; str += '<td>Date</td>'; str += '<td>Interest</td>'; str += '<td>Payment</td>'; str += '<td>Payment to Interest</td>'; str += '<td>Payment to Principle</td>'; str += '<td>Principle</td>'; str += '</tr>';
Now, it is the moment to create each row of the table with the values of monthly amortization.
for(var i = 0, h = r.length; i < h; i++)
{
str += '<tr>';
str += '<td>'+GETDATETIMESTRING( new Date(r[i]['date']), 'yyyy-mm-dd')+'</td>';
str += '<td>'+PREC(r[i]['interest'],2)+'</td>';
str += '<td>'+PREC(r[i]['payment'],2)+'</td>';
str += '<td>'+PREC(r[i]['paymentToInterest'],2)+'</td>';
str += '<td>'+PREC(r[i]['paymentToPrinciple'],2)+'</td>';
str += '<td>'+PREC(r[i]['principle'],2)+'</td>';
str += '</tr>';
}
The previous code has its particularities. By default the dates returned by the CALCULATEAMORTIZATION operation have the complete format including hours and seconds, In this form the information about hours and seconds is not relevant, so, it is preferred to use a short date format: yyyy-mm-dd. The date string will be formatted with the GETDATETIMESTRING operation, included in the Date module of developers version of the plugin (the second parameter is the format to use):
str += '<td>'+GETDATETIMESTRING( new Date(r[i]['date']), 'yyyy-mm-dd')+'</td>';
Another particularity is the use of the PREC operation. By default the CALCULATEAMORTIZATION returns the numeric values with all its decimals digits, for example: 366.873078125, but for humans it is common to identify the money representation with two decimal digits. So, I've used the PREC operation with the number 2 as the second parameter.
str += '<td>'+PREC(r[i]['interest'],2)+'</td>';
After creating all table rows, it is time to close the table, and print the results:
str += '</table>';
If you display the result directly in the calculated field, you will see a weird text (or very hard to understand) because the input fields in HTML are not able to display tables, in this case I've preferred to show the result in an "Instruct Text" field. I've inserted an "Instruct Text" field in the form, this type of field uses the class name "comment_are", and includes an <span> tag with the class "uh". Then, using jQuery to select the correct field, I've inserted the formatted result of the CALCULATEAMORTIZATION in the <span> tag included in the "Instruct Text" field:
jQuery('.comment_area .uh').html( str );
The complete equation is:
(function(){
var r = CALCULATEAMORTIZATION(fieldname1,fieldname3,fieldname2),
str = '';
if(r.length)
{
str = '<table cellpadding=" 10" >';
str += '<tr>';
str += '<td>Date</td>';
str += '<td>Interest</td>';
str += '<td>Payment</td>';
str += '<td>Payment to Interest</td>';
str += '<td>Payment to Principle</td>';
str += '<td>Principle</td>';
str += '</tr>';
for(var i = 0, h = r.length; i < h; i++)
{
str += '<tr>';
str += '<td>'+GETDATETIMESTRING( new Date(r[i]['date']), 'yyyy-mm-dd')+'</td>';
str += '<td>'+PREC(r[i]['interest'],2)+'</td>';
str += '<td>'+PREC(r[i]['payment'],2)+'</td>';
str += '<td>'+PREC(r[i]['paymentToInterest'],2)+'</td>';
str += '<td>'+PREC(r[i]['paymentToPrinciple'],2)+'</td>';
str += '<td>'+PREC(r[i]['principle'],2)+'</td>';
str += '</tr>';
}
str += '</table>';
}
jQuery('.comment_area .uh').html( str );
})()

The Chart.js module allwos to includes charts generated with the Chart.js API in the forms (Distributed with the Developer or Platinum versions of the plugin):
| Operation | Description | Demo |
|---|---|---|
| CFFCHART(canvas tag id, object with the data and options) | It is a proxy for the Chart method in the Chart.js API. The functions accepts the same parameters in the Chart function. The first parameter is the id of the canvas tag where the chart would be generated. The second parameter is a plain object with the labes, datasets, and options, required by Chart.js. Click here for the API Documentation. |
CFFCHART('canvas_id', {type:'bar', data:{labels:['Label A', 'Label B'], datasets:[{data:[fieldname1, fieldname2]}]}}) |
The process would be as follows:
* Insert a "HTML Content" field in the form with the canvas tag as its content:
<canvas id="canvas_id"></canvas>
* Uses the CFFCHART operation as part of the equation:
('canvas_id', {type:'bar', labels:['Label A', 'Label B'], datasets:[{data:[fieldname1, fieldname2]}]})
More information with a detailed description of parameters and practical demos in the post of the plugin's blog: Chart Generation
The "Troubleshoot Area & General Settings" section, allows correct some possible issues, or conflicts with third party plugins, and define the general settings.
The plugin calls the following list of filters and actions:
<SCRIPT>
function setSliderValue( clss, value )
{
var id = fbuilderjQuery('.'+clss+' input').attr( 'id' );
var fId = id.match(/_\d+$/);
fbuilderjQuery.fbuilder.forms[fId].getItem(id).setVal(value);
}
</SCRIPT>
(function(){
var v = fieldname1+fieldname2;
setSliderValue('my-field', v);
return v;
})()
(*) With the "Managing Fields" operations module the process is very simple, assuming the slider field is the fieldname1 and you want assign it the value: 50, include as part of the equation the piece of code:
getField(1).setVal(50);
Assuming there are two date fields: fieldname1, and fieldname2
To define as the "min" attribute of of the fieldname2 field the date selected in the fieldname1 field:
Insert a "HTML Content" field in the form with the following piece of code as its content:
<script>
fbuilderjQuery(document).on(
'change',
'[id*="fieldname1_"].hasDatepicker',
function (){ fbuilderjQuery('[id*="fieldname2_"].hasDatepicker').datepicker('option','minDate',this.value); });
</script>
To define as the "max" attribute of of the fieldname2 field the date selected in the fieldname1 field:
Insert a "HTML Content" field in the form with the following piece of code as its content:
<script>
fbuilderjQuery(document).on(
'change',
'[id*="fieldname1_"].hasDatepicker',
function (){ fbuilderjQuery('[id*="fieldname2_"].hasDatepicker').datepicker('option','maxDate',this.value); });
</script>
For selecting in the fieldname2 field, the date selected in the fieldname1 field plus a number of days (in the code below, 3 days after):
Insert a "HTML Content" field in the form with the following piece of code as its content:
<script>
fbuilderjQuery(document).on(
'change',
'[id*="fieldname1_"].hasDatepicker',
function (){
var d = fbuilderjQuery(this).datepicker('getDate');
d.setDate(d.getDate()+3);
fbuilderjQuery('[id*="fieldname2_"].hasDatepicker').datepicker('setDate',d); });
</script>
In some situations is required that the fields values have a specif format, or maybe allow to enter only a list of values. In these cases the current validation rules (digits, numbers, max value, min value, text length, required) are not sufficient, and would be needed new rules. This section describes how to create a new validation rule, and assing it to a field.
Assuming you need restricts the values of the fieldname1 field as US Zipcode, with the formats: #####-#### or #########, the regular expression used to validate the field's value is: /^\d{5}([\-]?\d{4})?$/
Insert a "HTML Content" field in the form, with the piece of code below as its content:
<SCRIPT>
fbuilderjQuery(document).one('showHideDepEvent', function(){
fbuilderjQuery
.validator
.addMethod(
"zipcode",
function(v,e)
{
return this.optional(e) || /^\d{5}([\-]?\d{4})?$/.test(v);
}
);
fbuilderjQuery.validator.messages['zipcode'] = 'The zipcode is invalid';
fbuilderjQuery('[id*="fieldname1_"]').addClass('zipcode');
});
</SCRIPT>
The previous code adds a new method to the "validator" object, applied to all input fields with the class name "zipcode", the method returns true if the input field is optional, or its value satisfies the format of an US zipcode. With the instruction: fbuilderjQuery.validator.messages['zipcode'] = 'The zipcode is invalid'; is defined the error message to display when the validation rule fails. The last instruction assign the class name: zipcode to the fieldname1 field, to apply on it the new validation rule.
The Developers version of the "Calculated Fields Form" plugin, allows storing the data submitted in a database different to the own plugin database.
To use this feature are required some basic skills, because should be edited the "cp_calculatedfieldsf_insert_in_database.php" file included in the code of plugin.
This file is a mockup to integrate the plugin with other MySQL database. The file should be modified manually because each database has its own structure, and gives to the users a total control on the process.
The file's edition:
Open the file with the text editor your choice. There are some text editors, widely recommended for code editing, like: Notepad++, Sublime Text, Vim, Atom, UEditor.
The first section of file allows defining the constants needed for connecting with the database, and its authentication:
define( 'DATABASE_HOST', '' ); define( 'DATABASE_USER', '' ); define( 'DATABASE_PASS', '' ); define( 'DATABASE_NAME', '' ); define( 'DATABASE_TABLE', '' );
The name of constants are auto-descriptives:
The plugin checks if the constants have been defined, before for running the insertion queries.
The second section to be edited by the developers, is the creation of the variables to use in the queries. The file includes some variables as a guide of section:
$field1 = mysqli_escape_string( $db_link, $params[ 'fieldname%' ] ); $field2 = mysqli_escape_string( $db_link, $params[ 'fieldname%' ] ); $field3 = mysqli_escape_string( $db_link, $params[ 'fieldname%' ] );
I'll explain this section with an example. Suppose you want store in the "my_users" table, the firstname, lastname, and email of the user, submitted through the form, and the corresponding fields in the form for these information are: fieldname1, fieldname2, and fieldname3, respectively. So, the variables are created like follow:
$field1 = mysqli_escape_string( $db_link, $params[ 'fieldname1' ] ); $field2 = mysqli_escape_string( $db_link, $params[ 'fieldname2' ] ); $field3 = mysqli_escape_string( $db_link, $params[ 'fieldname3' ] );
In the previous code has been created a varaible for each field in the form. All fields are included in the $params array.
After create the variables, is time to generate the insertion queries. The plugin includes a mockup for a hypotetical insertion query, that must be replaced with the structure of your database and the fields created previously.
mysqli_query( $db_link, "INSERT INTO `".DATABASE_TABLE."` (field1, field2, field3) VALUES ('$field1', '$field2', '$field3');" );
Returning to the previous example. If the columns of the table are: firstname, lastname, and email, respectively, the query should be modified like follow:
mysqli_query( $db_link, "INSERT INTO `".DATABASE_TABLE."` (firstname, lastname, email) VALUES ('$field1', '$field2', '$field3');" );
Pay attention, if the type of data in a column of table is a numeric value, should be removed the quotes around the variable name. For example, suppose the form includes a DropDown field for the year of birth, that evidently is a numeric value, I will assume this is the fieldname4. So, you should create a new variable for the new field:
$field4 = mysqli_escape_string( $db_link, $params[ 'fieldname4' ] );
and modify the insertion query too:
mysqli_query( $db_link, "INSERT INTO `".DATABASE_TABLE."` (firstname, lastname, email, year) VALUES ('$field1', '$field2', '$field3',$field4);" );
The $field4 variable is not closed between quotes.
A last tip: It is possible create as many insertion queries as needed, even can use the table name directly without use the constant defined in the first section.
The plugin adds a consecutive number to each form inserted in a webpage to prevent conflicts between different copies of a same form, starting in "1". The process will be explained in an example. I will suppose your form includes only one form created with the "Caculated Fields Form", and the form includes three fields: - a numeric field (fieldname1), a DropDown field (fieldname2), a checkbox field (fieldname3), and a single text field (fieldname4). Furthermore, the form fields should be prefilled with the values: 3 for the fieldname1, the choice with the value 4 in the fieldname2, tick the choices with the values: 1, and 2 for the fieldname3, and the "qwerty" text in the fieldname4, follows the steps below:
<SCRIPT>
cpcff_default = { 1 : {} };
cpcff_default[1][ 'fieldname1' ] = 3;
cpcff_default[1][ 'fieldname2' ] = 4;
cpcff_default[1][ 'fieldname3' ] = [1,2];
cpcff_default[1][ 'fieldname4' ] = "qwerty";
</SCRIPT>
Pay attention to the values of the fieldname3 and fieldname4. The fieldname3 is a checkbox, as it is possible select multiple choices, should be assigned an array of values. For the fieldname4, whose value is a text, it should be closed with quotes or double quotes.
The process will be explained with an example. Assuming will be populated the fields: fieldname3, and fieldname7 in the form B with the values of the fields: fieldname1, and fieldname2 submitted by the form A:
Note: I'm assuming here the form B is the unique form inserted in the thank you page, or at least the first one. For this reason in the next code the index or attribute in the cpcff_default variable is 1 (cpcff_default = { 1 : {} };)
[CP_CALCULATED_FIELDS_RESULT]
<SCRIPT>
cpcff_default = { 1 : {} };
cpcff_default[1][ 'fieldname3' ] = '<%fieldname1_value%>';
cpcff_default[1][ 'fieldname7' ] = '<%fieldname2_value%>';
</SCRIPT>
[/CP_CALCULATED_FIELDS_RESULT]
A particular case: If there are two forms in the thank you page, and you want populate the fields: fieldname3, and fieldname7 of the first form in the page, and the fields: fieldname2, and fieldname3 in the second form, the piece of code to use would be:
[CP_CALCULATED_FIELDS_RESULT]
<SCRIPT>
cpcff_default = { 1 : {},2 : {} };
cpcff_default[1][ 'fieldname3' ] = '<%fieldname1_value%>';
cpcff_default[1][ 'fieldname7' ] = '<%fieldname2_value%>';
cpcff_default[2][ 'fieldname2' ] = '<%fieldname1_value%>';
cpcff_default[2][ 'fieldname3' ] = '<%fieldname2_value%>';
</SCRIPT>
[/CP_CALCULATED_FIELDS_RESULT]
As you can see in the previous examples, the indices (or attributes) in the cpcff_default variable don't have relationship with the forms' ids. These indices (or attributes) indicate the possition of the form in the page, the first form, index 1, second form, index 2, and so on.
The "Caculated Fields Form" plugin includes multiple predefined templates to be used in the forms. The template is selected from the "Form Settings" tab, in the toolbar of the form builder, but can occur that the predefined templates are not sufficient to create a form with the look and feel you want.
The template's module in our plugin, can be extended easily to create new designs, to be used in the forms of website.
Into the "/wp-content/plugins/calculated-fields-form/templates" directory there are multiple folders, a folder for each template. The folders names have not restrictions, you simply should create a new folder for the custom template, with the name you want.
The only one required file in a template is the "config.ini" file, whose structure is:
prefix="cp_cff_custom" file="style.css" title="Custom Template" thumbnail="thumbnail.jpg" description="This is my custom template"
The description of attributes:
To implement a specific design to your forms, creates a CSS file, in the template directory (uses the file's name you prefers, but assings the file name to the file attribute in the config.ini file)
The stylepublic.css file defines the default appearance to all forms on website. The classes definitions start with #fbuilder, the ID value assigned to the form, to prevent conflicts with styles defined by other plugins or themes in the website. For extending and modify the styles from the custom template, should redefine the styles in your own CSS file, but prefixing the styles definitions, with the value entered in the prefix attribute of config.ini file.
I'll explain the process with an example. Suppose you want apply to the forms titles, the style rule font-size:1.5em, and you have defined the text: cp_cff_custom as the value of the prefix attribute, in this case the style's definition in the CSS file would be:
.cp_cff_custom #fbuilder .fform h1{font-size:1.5em;}
Apply this logic for the rest of classes in the CSS file.
After complete the template, you simply should select it from the settings page of the forms.
For printing only the form, but not the rest of page, please, follows the steps below:
<SCRIPT>
function printForm(){
var w = window.open(null, 'Print_Page', 'scrollbars=yes');
jQuery('#fbuilder input').each(function () {
var e = jQuery(this);
e.text(e.val()).attr('value', e.val());
if (e.hasClass('large'))
e.css('width', '100%');
if (typeof e.prop('checked') != 'undefined' && e.prop('checked'))
e.attr('CHECKED', e.prop('checked'));
});
var html = jQuery('#fbuilder').html();
jQuery('#fbuilder TEXTAREA').each(function () {
var e = jQuery(this).parent().html();
html = html.replace(e, jQuery(this).val());
});
jQuery('#fbuilder SELECT').each(function () {
var e = jQuery(this).parent().html();
html = html.replace(e, jQuery(this).find('option:selected')[0].text);
});
w.document.write(html);
w.document.close();
w.print();
}
</SCRIPT>
printForm();
