Please keep the plugin updated. Updates contain bug fixes as well as new features. The WordPress directory distributes the updates for the free version of the plugin. But for commercial versions, it would be necessary to register your copy of the plugin. The following link describes the registration process: CLICK HEREThis section mainly contains notes on features of the form builder that are too detailed to include in the main description.

Conditional rules

It is possible to show or hide form fields (dependent fields) based on the options selected in checkbox fields, radio buttons, the options selected in dropdown menus, or the result of calculated fields.

The value of a dependent field is zero when it is hidden/disabled. The plugin excludes the disabled form fields from the submission.

Additional details about the use of dependencies

Predefined values

The predefined values in the fields have two possible uses:

1- To fill the field by default. This makes it easier for the end-user to enter values.

2- Hint of the values to be entered in the field (like “Enter your name”). To use the predefined value as a placeholder, you must tick the “Hide predefined value on click” checkbox. The value will disappear once the user starts filling in the field. The calculated fields’ equations ignore placeholders.

The “User Instructions” attribute

The “User instructions” attribute in the field settings allows you to instruct the user on how to fill in the field. By default, the instructions appear as smaller text on the public website. But they can be configured as tooltips.

Adding CSS layout keywords

The “Add CSS layout keywords” attribute in the fields settings allows you to apply CSS styles to fields. You must only enter the name of the CSS class names, and not their definitions.

You can define the CSS classes via the “Customize Form Design” attribute in the “Form Settings” tab. This attribute contains a CSS editor with syntax highlighting and error checking.

If you want to assign several class names to the field, separate them by space characters.

The plugin includes multiple predefined classes that you can assign to the form fields.

More information about the form’s design can be found by reading the following post in the plugin’s blog:

Customizing the form’s design

The classes listed below allow you to align two, three, or four fields on the same line:


For example, if you want to put two fields on the same line, give both fields the class name “column2”.

There are other variants for displaying several fields on the same line, such as container fields (Div or Fieldset). Container fields allow you to select the number of columns in your configuration. The following post describes all the alternatives for positioning the fields in the form:

Formatting the form (distributing the fields in columns)

Multi-page form

To create multi-page forms, you must insert “Page break” controls between fields belonging to different pages.

When the user presses the “Next Page” button, the plugin validates the fields in the current form. If there is any validation error (such as an unfilled required field), the plugin stops the “Next page” action.

Hidden calculated fields

Calculated fields include a checkbox in the configuration that allows them to be hidden from the public website. This feature is essential in those fields that are used to calculate intermediate values or when we want to show the results only in emails or thank you pages.

Equation / Formula format for calculated fields

Below, some possible formulas are included as examples, but the possibilities are endless.

  • With simple mathematical operations:

    fieldname1 + fieldname2
    fieldname1 * fieldname2
    fieldname1 / fieldname2
    fieldname1 - fieldname2
    fieldname1 - fieldname2
  • With mathematical operations involving multiple fields and grouped fields:

    fieldname1 * (fieldname2 + fieldname3)
  • With rounding operations. Round the result to two decimal places:

    PREC(fieldname2 / fieldname3, 2)
  • There are infinite number of formulas that can be created using complex structures. For example, the following formula includes conditional statements:

    (function () {
    if (100 < fieldname3) return fieldname1 + fieldname2;
    if (fieldname3 <= 100) return fieldname1 * fieldname2;
  • For complex formulas/equations you must use the function format with return statement to return the result to the calculated field:

     (function () {
        var result = 0;
        /* Your code here */
        return result;
    }) ();

Operations and operators to use in equations/formulas

One of the “Calculated Fields Form” strengths is the ability to use any valid JavaScript code to implement the equations/formulas.

However, the plugin includes a wide variety of operations and …

I picked up this plugin years ago and have used it consistently ever since. I just love it and it does what we need it to do.

WARNING: The simple fact that we were informed by our website that an error had occurred wit the plugin calculated-fields-form made us upgrade the plugin to the latest level. But we were NOT informed about the simple fact that this "update" resulted in a cripled functionality of the plugin calculated-fields-form! Basic functionality like sending the form content by email was disabled and caused by this update. So to get our forms working we were forced to pay for the upgrade. And if we decided not to do so, all effort put into all the forms could be flushed down the drain! The fact that you one is ambushed and forced to pay for existing functionality in an initially free version of the software that has been deliberately downgraded to an unusable level is just a scam!
