[solved]Custom Validation?

[eluser]brucebat[/eluser]
Okay good news!

The function must not be getting called as I tried this in it

Code:

public function valid_time($str)
            {
                echo "hello world";
                return;  }

So it must be a problem with the function call.

The example says

The validation system supports callbacks to your own validation functions. This permits you to extend the validation class to meet your needs. For example, if you need to run a database query to see if the user is choosing a unique username, you can create a callback function that does that. Let's create a example of this.

In your controller, change the "username" rule to this:

$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
