af/form/restriction

Restrict a form based on custom conditions. Return false to display form normally or return a message which should be displayed instead of the form fields.

The first conditional in the example should always be included in order to not override other restrictions

<?php

function restrict_form( $restriction, $form, $args ) {
  // Added in case another restriction already applies
  if ( $restriction ) {
      return $restriction;
  }

  if ( condition_to_hide_form ) {
      return 'This message will be displayed instead of the form';
  }

  return false;
}
add_filter( 'af/form/restriction/key=FORM_KEY', 'restrict_form', 10, 3 );
