Multi level embed form in symfony 1.4

Question

I want to create multi-level embed form in symfony 1.4.

I have three forms:

1 - Question form, 2 - Option form and 3 - answer form.

In that, one question have many options fields and one option have many answers fields.

When I tried to add one more field in option criteria by rendering the HTML for answer fields using ajax and try to save form that time I am getting error Unexpected extra form field named "1"

And I have embedded Option form in Question form and Answer form in Option form respectively.

The below error is produce after submit form :

pick_type_option [0 [pick_type_answers [Unexpected extra form field named "1".]]]

Can any one please help me to find out the solution for this problem.

In advanced thanks

As it's unknown how many Option forms will be there during construction of the form (inside configure(), you have to override bind() method and add as many as needed:

class QuestionForm extends sfForm {

  public function configure() {
    $this->embedFormArray('question', new OptionForm);
  }

  private $formArray = array();

  public function embedFormArray($name, \sfForm $form, $decorator = null, $innerDecorator = null, $options = array(), $attributes = array(), $labels = array()) {
    $this->formArray[] = array($name, $form, $decorator, $innerDecorator, $options, $attributes, $labels);
  }

  public function bind(array $taintedValues = null, array $taintedFiles = null) {
    foreach($this->formArray as $fa) {
      $c = (isset($taintedValues[$fa[0]]) ? count($taintedValues[$fa[0]]) : 0);
      array_splice($fa, 2, 0, [$c]);
      call_user_func_array(array($this, 'embedFormForEach'), $fa);
    }

    return parent::bind($taintedValues, $taintedFiles);
  }
}
