Cart library: how to extend library class regex validation without messing with the core?

It's a public variable - so you can change it to anything you want.

Code:

$this->load->library('cart');
$this->cart->product_name_rules = 'ponies';

Or you could [url=http://ellislab.com/codeigniter/user-guide/general/core_classes.html]extend the library[/code] and just set it in there, which will then be in effect globally.
