extend Core functionality with my_changes

I have been searching all over for a good intro to extending cs-cart with the my_changes add-on, so please excuse me if this has been addressed or is not the place. I’d like to add some functions for querying custom tables in the db. All i can seem to find are explanations on how to change template files. I guess i’m just not sure how to reference the core functions files in the /core directory.

For instance:

i’d like to add functions to the /core/fn.catalog.php using my_changes

i’m using version 2.1.2. would someone be so kind as to give an example of the directory structure that the my_changes add-on requires to do this? It would be GREATLY appreciated.

Probably, some information here [url]http://docs.cs-cart.com/[/url] might be useful to you.

Also, here’s small example of using the “My changes” addon with PHP: [url]CS-Cart Documentation — CS-Cart 4.15.x documentation

Thanks. I definitely needed to review some of the documentation. I might have been going in the wrong direction with the my changes. i think i found what i needed in tbirnseth’s “php controllers” series.

You might want to review this thread which discusses the php side of the equation.
