More Information

The action is applied to an array for Rich Text form field. This function can be used for all form fields do_action( wpforms_process_validate_{$field_type}, $field_id, $field_submit, $form_data ).

For example, to use this for an Email field, you would use do_action( wpforms_process_validate_email, $field_id, $field_submit, $form_data ).

It’s important to note that field values are not sanitized until later on in the processing, at wpforms_process_format_{$field_type}.the


You can use this action to scan the Rich Text for a list of words that you’d like block the form from sending, such as profanity or you could use this action to look for certain words that would trigger another action like setting a value in a hidden field on your form that you can filter from entries.

This example, we’re going to search for any profanity in this field. If there is any profanity, the form will display an error and not send.

 * Check the paragraph text field for profanity.
 * @link
 * @param int     $field_id        Field ID.
 * @param array   $field_submit    Unsanitized field value submitted for the field.
 * @param array   $form_data       Form data and settings.

    // Optional, you can limit to specific forms. Below, we restrict output to form #3382.
    if ( absint( $form_data[ 'id' ] ) !== 3382 ) {
        return $field_id;

function wpf_dev_profanity_filter_rich_text( $field_id, $field_submit, $form_data ) {
    //Create your list of profanity words separated by commas
    $blocked_words = array( 
    foreach( $blocked_words as $word ) {
        if(strpos($field_submit, $word) !== FALSE ) {
            wpforms()->process->errors[ $form_data[ 'id' ] ][ $field_id ] = esc_html__( 'No profanity allowed.', 'wpforms' );
add_action( 'wpforms_process_validate_richtext', 'wpf_dev_profanity_filter_rich_text', 10, 3 );
