Description
Modify update (and other non-error) messages displayed by Gravity Forms in the WordPress admin.
Usage
add_action( 'gform_admin_messages', 'my_custom_function' );

Examples
This example demonstrates how we can append a ‘Preview Form’ link to any update message where a form ID is available in the query string.
add_action( 'gform_admin_messages', 'my_append_preview_form_link' );
function my_append_preview_form_link( $messages ) {
// get the form ID from the query string
$form_id = rgget( 'id' );
// if no form ID is available, let's not add the 'Preview Form' link
if ( ! $form_id ) {
return;
}
// loop through our error messages and append the 'Preview Form' link
foreach ( $messages as &$message ) {
$message .= ' <a href="' . site_url() . '/?gf_page=preview&id=' . $form_id . '">Preview Form</a>';
}
return $messages;
}
