Try Zend Framework vol.4 "Validate Date"

As you know, Zend Framework has a lot of fancy validators like Zend_Validte_Ccnum.
But, it comes to "Zend_Validate_Date", I have to be quiet, because it only allows "YYYY-mm-dd" format.
Date sometimes look like "YYYY/mm/dd" but the validator returns "false". :<

It's Okay. But it should be more flexible, isn't it?

Zend Framework has Date class which is pretty powerful to create date object, but it's also powerful as Date validator.
So I wrote a Date validator.

library/Hoge/Validate/Date.php

<php
require_once 'Zend/Validate/Abstract.php';
require_once 'Zend/Date.php';

class Hoge_Validate_Date extends Zend_Validate_Abstract
{

  /**
   * Invalid date error message.
   */
  const INVALID = 'dateInvalid';

  /**
   * Validation failure message template.
   *
   * @var array
   */
  protected $_messageTemplates = array(
      self::INVALID => "'%value%' does not appear to be a valid date"
  );

  /**
   * Defined by Zend_Validate_Interface
   *
   * Return if the date is correct.
   *
   * @param  string $value
   * @return boolean
   */
  public function isValid($value)
  { 

      $valueString = (string) $value;

      $this->_setValue($valueString);

      if (!Zend_Date::isDate($value)) {
          $this->_error(self::INVALID);
          return false;
      } 

      return true;
  } 

}

To use it
application/controller/HogeController.php

<php
function dateValidateAction()
{
  $date = '2004/02/29';

  require 'Hoge/Validate/Date.php';
  $validator = new Hoge_Validate_Date();
  echo $validator->isValid($date);
  exit;
}

Return "true".
It distinguish "/" and validate the Date correctly!! :p
