The functions below can be used to get a list of all Gravity Forms whose fields have a specific CSS class:
| <?php | |
| /** | |
| * Get a list of Gravity Forms whose fields have a CSS class. | |
| * | |
| * @param string $css_class The CSS class to search for. | |
| * | |
| * @return array The list of forms in this format: [<form ID> - <form title>] => <array of fields that have CSS class> | |
| */ | |
| function get_gravity_forms_with_css_class( $css_class ) { | |
| return array_reduce( GFAPI::get_forms(), function( $forms_with_css_class, $form ) use ( $css_class ) { | |
| $fields_with_class = get_gravity_form_fields_with_css_class( $form, $css_class ); | |
| if ( $fields_with_class ) { | |
| $forms_with_css_class[ "{$form['id']} - {$form['title']}" ] = $fields_with_class; | |
| } | |
| return $forms_with_css_class; | |
| }, [] ); | |
| } | |
| /** | |
| * Get all fields in a Gravity Form that have a CSS class. | |
| * | |
| * @param array $form The Gravity Form data. | |
| * @param string $css_class The CSS class to search for. | |
| * | |
| * @return array Fields that have the CSS class or empty array if none. | |
| */ | |
| function get_gravity_form_fields_with_css_class( $form, $css_class ) { | |
| return array_filter( $form['fields'], function( $field ) use ( $css_class ) { | |
| return in_array( $css_class, explode( ' ', $field->cssClass ), true ); | |
| } ); | |
| } |
Calling the first function looks like get_gravity_forms_with_css_class( 'list-users2' ) and the results it returns look like this:
The keys of the array include the form ID and title. Each value is an array of all the fields within that form that have the CSS class.
