How to retrieve form_id from an element template?

Hi Min,

jsut take a look here. There is the to_json method explained:

public function to_json( $element ) {
    // This method can be used to add additional data that can be used
    // by the frontend template. All keys in the $data array will be available
    // as individual variables in the template.
    //
    // Checkout the Torro_Element_Type base class to see what is available
    // by default. Make sure to always call the parent method (see below).

    $data = parent::to_json( $element );

    $data['my_custom_value'] = 'some-value';

    return $data;
  }

Also you have the function

torro()->forms()->get_current_form_id();

If you combine it, you will get this:

public function to_json( $element ) {
    $data = parent::to_json( $element );
    $data['form_id'] = torro()->forms()->get_current_form_id();
    return $data;
  }

After you have added this to the element, the element template should have the variable $form_id.

Does it work?

Great! 🙂
