How to validate a date without day with sfForm? - validation

Question

I'm creating a payment form with symfony 1.4 , and my form has a date widget defined like this, so that the user can select the expiration date of his credit card:
new sfWidgetFormDate(array(
'format' => '%month%/%year%',
'years' => array_combine(range(date('Y'), date('Y') + 5), range(date('Y'), date('Y') + 5))
Notice the absence of %day% in the format like in most payment forms.
Now my problem is that sfValidatorDate requires the 'day' field not to be empty. To work around this, I created a custom validator using a callback, which works well:
public function validateExpirationDate($validator, $value)
{
$value['day'] = '15';
$dateValidator = new sfValidatorDate(array(
'date_format' => '#(?P<day>\d{2})(?P<month>\d{2})(?P<year>\d{2})#',
'required' => false,
'min' => strtotime('first day of this month')));
$dateValidator->clean($value);
return $value;
}
I feel there might be a simpler way to achieve this. What do you think? Have you already solved this problem in a cleaner way?

Answer 1

How do you store the date? If you just store month and year as integers or strings, then you can just make 2 choice widgets. But if you store it as datetime (timestamp), then you need a valid date anyway. This means that you need to automatically assign values to 'day' (usually first or last day of the month).
class YourForm extends BaseYourForm
{
public function configure()
{
$this->widgetSchema['date'] = new sfWidgetFormDate(array(
'format' => '%month%/%year%'
));
$this->validatorSchema['date'] = new myValidatorDate(array(
'day_default' => 1
));
}
}
class myValidatorDate extends sfValidatorDate
{
protected function configure($options = array(), $messages = array())
{
$this->addOption('day_default', 1);
parent::configure($options, $messages);
}
protected function doClean($value)
{
if (!isset($value['day']))
{
$value['day'] = $this->getOption('day_default');
}
return parent::doClean($value);
}
}

There's no need to use a custom validation class: you can simply override the tainted values passed to your bind() method:
<?php
// in your form class
public function bind(array $taintedValues = null, array $taintedFiles = null)
{
$taintedValues['date']['day'] = 1;
return parent::bind($taintedValues, $taintedFiles);
}

I used simplest way, for validate credit card expiration day:
$post_data = $request->getParameter('my_form');
$post_data['card_exp']['day'] = 1; //sets the first day of the month
$this->form->bind($post_data);
Hope this helps somebody.

I solve this first in the form class
$year = range(date('Y'), date('Y') - 50);
$this->widgetSchema['date'] = new sfWidgetFormDate(array(
'format' => '%year%',
'years' => array_combine($year, $year),
'can_be_empty' => false
));
Next...
public function bind(array $taintedValues = null){
$taintedValues['date']['day'] = '01';
$taintedValues['date']['month'] = '01';
parent::bind($taintedValues);
}
The field in the database is date type DATE.
