Date validation?

[eluser]tison[/eluser]
I updated wdm*'s solution for version 1.7.2, and to take in my particular date format (mm/dd/yyyy). I need to clean up the repeated else, but it works well:

In <b>/libraries/MY_Form_validation.php</b>:

Code:

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

class MY_Form_validation extends CI_Form_validation {

    function __construct()
    {
        parent::CI_Form_validation();
    }

    // --------------------------------------------------------------------

    /**
     * Valid Date (human format mm/dd/yyyy)
     *
     * @access    public
     * @param    string
     * @return    bool
     */
    function valid_date($str)
    {
        if ( ereg("([0-9]{1,2})/([0-9]{1,2})/([0-9]{4})", $str) )
        {
            $arr = split("/", $str);    // splitting the array
            $yyyy = $arr[2];            // year
            $mm = $arr[0];              // month
            $dd = $arr[1];              // day
            if(is_numeric($yyyy) && is_numeric($mm) && is_numeric($dd)){
                return ( checkdate($mm, $dd, $yyyy) );
            } else {
                $mythis =& get_instance();
                $mythis->form_validation->set_message('valid_date', 'The %s field must be in format: mm/dd/yyyy.');
                    return FALSE;
            }
        }
        else
        {
            $mythis =& get_instance();
            $mythis->form_validation->set_message('valid_date', 'The %s field must be in format: mm/dd/yyyy.');
            return FALSE;
        }
    }
    
}

Then to call our validation rule from our controller:

Code:

$this->form_validation->set_rules('dob', 'Date of Birth', 'required|valid_date');

Pachow.
