The “Custom” form action type allows you to hook a WordPress action into form processing.
The “Hook Tag” setting specifies what WordPress action hook to call during the submission process.
During submission the specified “Hook Tag” is passed a $form_data array variable. This array contains the form id, form fields, and form settings data as top level keys in the array.
Notice: The $ninja_forms_processing super global has been removed. All form data is available via the passed $form_data parameter.
| <?php | |
| /** | |
| * @tag my_ninja_forms_processing | |
| * @callback my_ninja_forms_processing_callback | |
| */ | |
| add_action( 'my_ninja_forms_processing', 'my_ninja_forms_processing_callback' ); | |
| /** | |
| * @param $form_data array | |
| * @return void | |
| */ | |
| function my_ninja_forms_processing_callback( $form_data ){ | |
| $form_id = $form_data[ 'form_id' ]; | |
| $form_fields = $form_data[ 'fields' ]; | |
| foreach( $form_fields as $field ){ | |
| $field_id = $field[ 'id' ]; | |
| $field_key = $field[ 'key' ]; | |
| $field_value = $field[ 'value' ]; | |
| // Example Field Key comparison | |
| if( 'my_field' == $field[ 'key' ] ){ | |
| // This is the field that you are looking for. | |
| } | |
| } | |
| $form_settings = $form_data[ 'settings' ]; | |
| $form_title = $form_data[ 'settings' ][ 'title' ]; | |
| } |
Note that the callback cannot update the submitted form data as this is a WordPress action and not a filter. The callback method should be a void return method.
