[Forminator] Filter profanities submitted through a form

One of my clients would like to add a profanity filter to Forminator form. His goal is to not allow the form to be submitted when the content contains banned words. Can that be achieved?

    Hi there, thanks for using Forminator,

    We created a fix for you, so you can validate form fields against and filter unwanted words.

    You can add the above snippet in a mu-plugin. If you are not familiar with mu-plugins, you can read more about them here:


    You can download you plugin here:


    By clicking Download ZIP on the upright part, then unzip and upload it to your mu-plugins directory.

    Before upload this snippet, make sure to update the following code to reflect your forms/fields.

    private $fields_to_check = array(
    // User defined - One form per line with selected fields (must exists in forms' settings)
    // Example: $form_id => array('field-1', 'field-2', ..., 'field-n')
    1097 => array( 'textarea-1' )
    private $profanity_filter = array(
    // User defined - One word pre row

    As we do comprehensive tests on our code, sometime we may miss something, if so, report it to assist you further.

    Hope this helps!

    Kind regards!
