This action hook can be used to inject Javascript into the SetDefaultValues() function on the form editor page. Use this hook to define default field properties when creating new field types.


add_action( 'gform_editor_js_set_default_values', 'set_defaults' );


This example changes the default label for a new field type

add_filter( 'gform_add_field_buttons', 'add_new_field' );
function add_new_field( $field_groups ) {
    //Adds a new field to the end of the standard fields list
    $field_groups[0]['fields'][] = array( "class"=>"button", "value" => 'My Field', "onclick" => "StartAddField('my_field_type');" );
    return $field_groups;

add_action( 'gform_editor_js_set_default_values', 'set_defaults' );
function set_defaults(){
    //this hook is fired in the middle of a switch statement,
    //so we need to add a case for our new field type
    case "my_field_type" :
        field.label = "My Default Field Label"; //setting the default field label
