Date validation?

[quote author="eSSeneX" date="1348673104"]After a bit of research I came out with this:

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Form_validation extends CI_Form_validation
{
    
    function __construct($config = array())
     {
          parent::__construct($config);
     }
    
    /**
     * Validates a date (dd/mm/yyyy)
     *
     * @param type $date
     * @return boolean
     */
    public function date($date) {
        if (!empty($date))
        {
            if (preg_match("/^(\d{1,2})[- \/.](\d{1,2})[- \/.](\d{4})$/", $date, $values))     // Is a date format (dd mm yyyy)
            {
                if (checkdate($values[2], $values[1], $values[3]))    // Date really exists
                {
                    return TRUE;
                }
            }
        }
        return FALSE;
    }
}

/* End of file: MY_Form_validation.php */
/* Location: application/core/MY_Form_validation.php */

By now it seems to work pretty well. I hope CI includes something for this stuff in future...[/quote]
Not all countries, or even applications, use date in that format. It would have to be a lot more robust, like pass the expected format in as the 2nd parameter as well as an optional delimiter for the date separator to use.
