Symfony 1.4 form checkbox array to string conversation - php

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.

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.
