Overriding module's functions to add custom rules events?

Posted by Strae on November 12, 2012 at 12:02pm

Hello guys, few days ago i made this edit to commerc_cart module: http://drupal.org/node/1782590

Now, my obvious problem is that if I update that module, all my custom events get lost.

Im wondering if there is a way to override the function where the module invoke my custom events (commerce_cart_view() in this case).

What can be a good practice to place (and mantain) custom rules events?

Any module can provide events to rules. Instead of altering the commerce module, simply create your own module (i always create a 'custom' module for these type of site customizations) and put your custom event there.

This is exactly what i meant to, but if you look the link I posted, to implement my own new event i should somehow override commerce_cart_view() function (as example, here i added the commerce_cart_cart_view_before and after events).

So how to do that?
