I'm using CodeIgniter and when I do a POST of a <textarea> using an AJAX call through jQuery, I get a Disallowed Key Characters error and I don't know why. Is there a solution to this?

I ran into this problem with CodeIgniter and found a solution here: http://codeigniter.com/forums/viewthread/140333/. It involves either making changes to system/libraries/Input.php in CodeIgniter or removing characters forbidden by the regular expression.

These lines are where the error message originates:

if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))
{
    exit('Disallowed Key Characters.');
}
