Overriding functions/html_output.php

Zen Cart 1.3.8a
Database Patch Level: 1.3.8
Server OS: Linux 2.4.20PIII
PHP Version: 4.4.2 (Zend: 1.3.0)
Database: MySQL 4.1.19-standard

I would like to override the functions in the html_output.php file that output HTML tags.

Where do I put these functions, and what replacement structure do I need to use to remove / disregard the previously defined versions of these functions so I dont end up with PHP errors saying I duplicated something.

There is no in-built override system for files in the includes/functions folder, but I recentyly figured out a method to do it by utilizing the override capabilities within the autoload/init_includes system.

First, make a copy of includes/init_includes/init_general_functions.php and save it in the includes/init_includes/overrides/ folder. Then edit that file to modify the loading of the html_output.php file so that it calls the file from an overrides folder like:

Code:

---

require(DIR_WS_FUNCTIONS . 'overrides/html_output.php');

---

Then you can create your new folder includes/functions/overrides/, and put an edited copy of html_output in there. This way you can edit or add functions within html_output.php and not have to worry about duplicate functions warnings, or about your changes getting overwritten during an upgrade.

You can use a similar method for overriding anything in the functions or classes folders, which don't have an inherent override capability.

Awesome! Thank you! This is the perfect solution!

wow, it really helped me as well bunyip. I was looking into fixing the size of the header 2 banner regardless the size of the original image.
So I overrided banner.php and added two parameters to function zen_display_banner, width and height, both to be passed at the same time to zen_image, so that the image will be resized if needed.
