Using Gravity Forms ‘gform_form_pre_results’ PHP filter

The gform_form_pre_results filter allows you to modify the Form object before the results are calculated in the admin results page. This is primarily used by add-ons implementing the Add-On Framework.


add_filter('gform_form_pre_results', 'your_function_name');

To target a specific form, add the form ID after the hook name:

add_filter('gform_form_pre_results_10', 'your_function_name');


  • $form (array): The form object.
