Form Validation callback rules in controllers are viewable URLs - El Forum - 02-14-2009

I just discovered that if I create a function in my Controller to use as a callback rule in my Form Validation rules, the callback function can be requested as a viewable page. Might I suggest that callback functions in Controllers be defined as a private function and then just prefix "callback" instead of "callback_" to it in the rules for Form Validation to use it.
Thoughts?

Just underscore your callbacks and then use callback__function in your rules. (That's two underscores, since "callback_" is the prefix and "_function" is the function to call, which is private)

I get an error:
PHP Fatal error: Call to private method Users::_email_check() from context 'CI_Form_validation' in /system/libraries/Form_validation.php on line 589
and I use callback__email_check
and private function _email_check($email)
any suggestion?

Easy. Make your function public.

This really is an issue for me too. Callback functions should not be URL-accessible. Any suggestions?
EDIT: Ah, sorry, my mistake. Two underscores indeed work. Forgot to use an underscore for the first parameter of the set_message() function.

because I just came across the same issue again, here's an example:
if your private callback function is something like this:
[code]function _my_private_callback_function($variable) {}[code]
make sure that within this you set your custom error message as follows
[code]$this->form_validation->set_message('_my_private_callback_function', 'Error message text');[code]
(notice the underscore here also)

Cool. I just had the same question and this seems to work well!
