Plugin Documentation

How it works?

From the dashboard/configuration area the process is as follows:

1. Insert data fields into the form
2. Insert a calculated field and define the calculation rule on it to store the calculated value
3. Configure the general form processing, email and PayPal settings if needed
4. Publish the form from a post or page (go to edit posts or pages).

From the end user (visitor) point of view, the process is as follows:

1. The user fills the data fields
2. The calculated fields (if any) will automatically show the calculated value
3. If the form Processing is enabled:
   • If PayPal integration isn't enabled:
     1. The user clicks "submit" and you (the website owner or administrator) receive a notification email with the data posted by the user.
     2. The user receives an automatic "confirmation/thank you" email.
     3. The user is redirected to a "confirmation/thank you" page into your WordPress website
   • If PayPal integration is enabled:
     1. The user clicks "submit" and is automatically sent to PayPal for the payment
     2. In background (transparent to the user): The request is saved into the local database and mark as "un-paid"
     3. The user completes the payment at PayPal
     4. In background (transparent to the user): Upon completed the payment, you (the website owner or administrator) receive a notification email with the data posted by the user.
     5. In background (transparent to the user): The request is marked as "paid".
     6. The user receives an automatic "confirmation/thank you" email.
     7. The user returns to a "confirmation/thank you" page into your WordPress website

Managing Forms

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:

• ID: Identification number of the form, useful when publishing an specific contact form.
• Form Name: Name to identify the form. Visible only from the admin area.

The Form Builder

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...).

SELECT column1 AS value, column2 AS text FROM tablename WHERE column3 > 5 ORDER BY column2 ASC LIMIT 5

Settings area of the forms

For each form you will be able to edit the following settings:

Form Builder: Already explained in the previous sections (see above).

Displaying Form Summary in the Thanks Page

• Go to the thanks page
• Press the icon indicated in the next image, to insert a shortcode with format [CP_CALCULATED_FIELDS_RESULT]

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 .

Associate a same thank you page with multiple forms

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]

Special tags in the notification emails and the thank you pages

There are special tags that can be used in the notification emails to display the forms information:

<%INFO%>, the tag <%INFO%> is replaced by the labels and values of fields that are submitted from the form.

To insert only specific fields, use the format <%fieldname#%>, for example, if you want include the fieldname1 and fieldname3 in the notification email, use the tags <%fieldname1%>, and <%fieldname3%>, the tag will be replace by the pair: label-value of field.

To insert only the field's label, use the format <%fieldname#_label%>, for example <%fieldname1_label%>

To insert only the shortlabel (that is used too in the CSV files), use the format <%fieldname#_shortlabel%>, for example <%fieldname1_shortlabel%>

To insert only the field's value, use the format <%fieldname#_value%>, for example <%fieldname3_value%>

To display all previous tags only if the fields have been filled by the users, you should use the attribute if_not_empty in the tags:

<%INFO if_not_empty%>
<%fieldname# if_not_empty%>
<%fieldname#_label if_not_empty%>
<%fieldname#_value if_not_empty%>

There are other special attributes to use in the tags. The values of the attributes are closed between the symbols {{...}}:

before: The attribute allows to define a symbol, or a HTML tag, to display before the field in the notification email <%fieldname# before={{<strong>}} after={{</strong>}}%>

after: The attribute allows to define a symbol, or a HTML tag, to display after the field in the notification email <%fieldname# after={{<br />}}%>

These attributes give a big control over the information included in the notification emails. For example, inserting a tag like:

<p><%fieldname1 if_not_empty%></p>

Inserts in the notification email, the pair of tags: <p></p>, if the value of the "fieldname1" field is empty. But if you inserts the previous tag with the attributes: before and after, like follow:

<%fieldname1 if_not_empty before={{<p>}} after={{</p>}} %>

The pair of tags <p></p> won't be inserted in the notification email, if the value of the fieldname1 field is empty.

separator: Allows to define a separator symbol to insert between the field's label, and its value. For example, if you insert the tag like: <%fieldname1 separator={{:}}%>, it would be replaced by field label : field value

There are some special tags to define dependencies in the notification emails: <%fieldname#_block%><%fieldname#_endblock%>

For example, to insert the fields: fieldname2 and fieldname3 in the email, only if the fieldname1 field was submitted, should be inserted the following tags in the email:

<%fieldname1_block%>
<%fieldname2%>
<%fieldname3%>
<%fieldname1_endblock%>

To include the URL to the uploaded file, if the file field is the fieldname1, the tag to insert in the email and thank you page would be: <%fieldname1_url%>, but if the fieldname1 supports multiple files, the corresponding tag would be: <%fieldname1_urls%>

To display the final price, after apply the discount if was defined, use the tag <%final_price%>

To display the coupon/discount applied, if was applied a discount, uses the tag <%coupon%>

To display only the coupon code, the discount text, use the tag <%couponcode%>

To display the payment option selected, in case that PayPal has been set as optional, use the tag <%payment_option%>

In the recurrent payments to display the id of the subscription, use the tag <%subscription_id%>

To include an unique number that identifies the submitted data into the system, uses the tag <%itemnumber%>. This number allows to identify easier the PayPal transference, and could be used as an order reference.

To include the form's id, uses the tag <%formid%>. Allows to identify the form that was submitted.

To include the ip address of the user, <%ipaddress%>

To include the date in the format: mm/dd/yyyy, <%currentdate_mmddyyyy%>

To include the date in the format: dd/mm/yyyy, <%currentdate_ddmmyyyy%>

Create JavaScript variables to be used in the equations

- From GET, or POST parameters, SESSION variables, or COOKIES

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:

Definig default values

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".

Create direct variables

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

Create a direct variable through the Forms Shortcode

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.

Equations Format for Calculated Fields

The equations allowed by the plugin "Calculated Fields Form" are really powerful tools.

Need more controls or operations?
Install the CP BLOCKS plugin:
- with buttons
- testimonial blocks
- additional features
...and more

It is possible create simple equations like follow:

With simple mathematical operations:

fieldname1+fieldname2

fieldname1*fieldname2

fieldname1/fieldname2

fieldname1-fieldname2

or mathematical equations with multiple fields and fields grouping included.

fieldname1*(fieldname2+fieldname3)

The equations may include a group of more specific operations

some of them available as buttons in the plugin's interface, the other operations should be typed manually in the equation's editor:

Pay special attention to the next two operations. The first of them, very extended its use in equations for calculations the cost of products and services, and the other one to obtain a date.

Sample valid equations:

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.

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

Logical Module

The logical module include the following functions:

Financial Module

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)
			},
			...
		]

• principle: how much remains to pay.
• interest: is the accumulated of interest paid until this date.
• payment: is the monthly payment (payment of interests and payment of principle).
• paymentToPrinciple: is the part of payment that is considered as payment of principle.
• paymentToInterest: is the part of payment that is considered as payment of interest.
• date: is the date of payment.

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 );
})()
