Form Validation Error

[eluser]CroNiX[/eluser]
callbacks need to be public or the validation class can't access them.

If you want to make it "private" so it's not accessible via the URL, CI lets you prefix the method name with an underscore, and do the same when you are setting the rules.

Code:

public function _username_exists($str)

...

Code:

//2 underscores
callback__username_exists
