Symfony 1.4 form checkbox array to string conversation

Question

I have following error during creating checboxes in Symfony 1.4 app. Checkboxes are rendered but with "Array to string conversation" error.

Below is my code.

Form

$this->setWidget('emails', new sfWidgetFormChoice([
      'label'    => 'Emails',
      'expanded' => true,
      'multiple' => true,
      'choices'  => array('test', 'test2'),
    ]));

Render

<div class="container emails">
    <fieldset>
      <legend>
        <?php echo $form['emails']->renderLabel(); ?>
      </legend>
        <?php echo $form['emails']->render(); ?>
        <?php echo $form['emails']->renderError(); ?>
    </fieldset>
  </div>

Error

Notice: Array to string conversion in /var/www/html/symfony/1_4_1/lib/widget/sfWidgetFormSelectCheckbox.class.php on line 103

Notice: Array to string conversion in /var/www/html/symfony/1_4_1/lib/widget/sfWidgetFormSelectCheckbox.class.php on line 10

My Php version is 5.5.8 Symfony version 1.4.19

I know that the best way would be move app to newest symfony version, but this application is too large to rewrite.

Anyone have idea how to solve it?

//Edit

I noticed that if I change code to

$arr = [];
    array_push($arr, 'test');
    array_push($arr, 'test2');


    $this->setWidget('emails', new sfWidgetFormSelectCheckbox([
      'label'    => __('Adresy email'),
      'choices'  =>$arr,
    ]));

it returns any errors, but if I add one more value to array, errors shows again.

Whole class code

class EmailFooterGeneratorForm extends BaseForm

Answer 1

It is a bit late, but since I was having this issue and someone else may need it, I found that the issue was that I was using a sfWidgetFormChoice set to be multiple, but I didn't tell it to the validator.

The solution is just to pass the option to it as well.

End up having something like

$this->validatorSchema['choices_name'] = new sfValidatorChoice([
    'required' => false,
    'multiple' => true,
    'choices'  => $choices
]);

I'm using it in a Form class, that's why you see $this->validatorSchema, if you are using it anywhere else, like in the OP case, just add that 'multiple' => true as option in the options array.
