Hi John,
Unfortunately, most code snippets are meant to be implemented by programmers with knowledge of PHP – that’s why I give them as hints for other developers to use on their websites. Most snippets are for use in functions.php
and some of them can be copied over ‘as is’, but some others need extending to fit a specific situation.
The snippet above is very schematic, and will need extra tweaking by a programmer. Your setup and requirements are quite specific, so WP Tiles itself doesn’t accommodate for it out of the box. What the above snippet does, is show how you can query custom posts and use them inside tiles in WP Tiles. It is meant to be used in a page template (or as a custom shortcode, maybe).
There are quite a few resources out there that can help you get an understanding of both PHP and programming with WordPress. I don’t know which site would be the best to start at, but Google around! There’s heaps of beginner guides. It’s easier than it looks to get started with programming for WordPress!
Cheers,
Mike
