Problems with sfValidatorChoice

Question

I have some problems with sfValidatorChoice. This is the array for the choice:

$branches = array(123 => 'Value 1', 456 => 'Value 2', 789 => 'Value 3')

where the numbers are given IDs. To have a default value I do this:

$choices_branches = array_merge(array('default' => 'Bitte wählen'), $branches);

In the form class I do this:

$this->setWidgets(array(
    'branches'    => new sfWidgetFormChoice(array(
                        'choices'  => $choices_branches,
                        'expanded' => false,
                        )),
...))

and this is the validator:

$this->setValidators(array(
  'branches'    => new sfValidatorChoice(array('choices' => array_keys($branches))),
  ...
))

But when I choose for example Value 1 and try to submit the form I get an Invalid Error.

Could anybody help?

From php.net

Don't forget that numeric keys will be renumbered!

You should do the following:

$choices =  array(123 => 'Value 1', 456 => 'Value 2', 789 => 'Value 3');
$this->setWidget('branches', new sfWidgetFormChoice(array(
    'choices'  => array('' => 'Bitte wählen') + $choices,
    'expanded' => false,
));
$this->setValidator('branches', new sfValidatorChoice(array(
    'choices' => array_keys($choices),
));
