Valid url check in form validation

[eluser]Quaze[/eluser]
Just as Aidehua i made a MY_ library.
Only i used the php built in function filter_var

so it gets more clean, and you dont need to prep_url.

Code:

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

class MY_form_validation extends CI_form_validation {

    function valid_url($str){
            if(filter_var($str, FILTER_VALIDATE_URL)){
                return TRUE;
            }
            else{
                return FALSE;
            }
        }
}

EDIT:

Also could be:

Code:

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

class MY_form_validation extends CI_form_validation {

    function valid_url($str){
            return filter_var($str, FILTER_VALIDATE_URL)
            }
}
