Ever wonder how to add counter/numbered classes to your posts? Is this the fourth post or the seventh? Well, if you have wished upon a star (or even if you didn’t, but it was more like cursing out your computer, that’s fine too), then your wish is about to come true with this tutorial.

In this tutorial’s example, we want our blog posts to have classes like “article-number”, and we can achieve this using the post_class(); function and a counter that we’ll set as a global variable.

It’s not as hard as you think. Also, keep in mind that this is a technique that can be applied to other scenarios too, and it’s not limited to just adding classes to our blog posts. Well, let’s get started, shall we?

Before we begin:

  1. Some familiarity with loops and general PHP will help.
  2. Might want to review what variables are. I also go over variables with better analogies in an old article of mine on the Pixafy Blog: Understanding WordPress’ $args Variable
  3. Make sure you have a theme that you can edit files in – for my example, I’m using TwentyThirteen. The files I’ll be working in are: functions.php, index.php, and content.php.

What we’re going to achieve:

In a nutshell, you can apply a custom template to a specific category just by naming the template file with a convention that gets automatically picked up by WordPress. It’s a really awesome feature to take advantage of, but there’s one problem.

Category.php will not apply to the category’s children/sub-categories.  So then, how do we apply a template to sub-categories? After lurking around online to find forum threads like this, and brainstorming with a co-worker of mine, I found some solutions to the problem and wanted to share them.

Before we begin:

  • You should have some knowledge as to how category.php works in a theme
  • You should have some basic understanding of PHP or at the very least, have taken a look at WordPress’ Conditional Tags
  • You should have access to your theme’s files for editing purposes
