Can not extend Form Validator core library

[eluser]patwork[/eluser]
You don't need to use get_instance() when you're in extended class. This will work:

Code:

$this->set_message('valid_url', 'The %s field must contain a valid url.');

If you're not sure MY_Form_validation is properly loaded, the best place to check it is it's constructor. Try to add something like:

Code:

function __construct()
{
    echo "HELLO FROM MY_FORM_VALIDATION";
    parent::__construct();
}

Only for debug purposes, of course
