从形式选择Symfony 1.4中获取价值

Question

how I can get value from form choice widget of submitted form?

Now it returns only integer index of selected option, but I need a value.

Below is my code:

$this->setWidget('emails',new sfWidgetFormChoice([
      'label'    => __('Emails'),
      'expanded' => true,
      'multiple' => true,
      'choices'  => ['[e-mail]', '[e-mail]'],
    ]));

$this->setValidators([
      'emails' => new sfValidatorChoice(
          ['choices' => array_keys($this->getDefault('emails')), 'multiple' => true],
          ['required' => __('Required')]),

Answer 1

The choice widget can take a choices parameter with an associative array to define both the value and the displayed text of each option.

'choices'   => array('[e-mail]' => '[e-mail]', '[e-mail]' => '[e-mail]'),

This will submit the email as the value, however now you have potential security issues. Make sure you are enabling CSRF protection and properly validating the input at a minimum.
