plugin-ninja-forms

Finally I have found a way to accomplish this , The solution to problem is to call update the field setting function function ninja_forms_change_required_field(){ add_action( ‘ninja_forms_before_pre_process’, ‘ninja_forms_code’ ); } add_action( ‘init’, ‘ninja_forms_change_required_field’ ); function ninja_forms_code(){ global $ninja_forms_processing; if(!is_user_logged_in()){ $data[‘req’] = ‘0’; $ninja_forms_processing->update_field_settings(135, $data); } } If a field is required then then $data[‘req’] = ‘1’

Please use Ninja Forms support. They recently made a large update and are continuously making improvements.
