Using Action Hooks in WordPress Child Themes

In this post we’ll review how to write a PHP function and go over the basic idea of how you can use Action Hooks in your WordPress Theme. We’ll take a look at a practical example of injecting a Welcome Blurb into your Theme without touching the existing code and we’ll also look at how to remove existing content being injected into Theme Hooks.

Packing Up A Function

Action hooks are in a lot of WordPress Themes nowadays. There’s a good reason for that but you’re probably wondering what the big deal is right? They’re such a big deal because firstly, they’re incredibly easy to use and secondly, because they’re extremely powerful.

If you want to get started with them we’re going to have to take a look at how to write a PHP function again. Don’t worry, we’ll keep it pretty simple.

How I used a WordPress Child Theme To Redesign My Blog

Problem: You want to take advantage of WordPress Parent-Child Themes but you want more control than is usually afforded through CSS alone. What about adding a Favicon? Or a link to a custom stylesheet for IE fixes.? Or editing the menu? How do you do that without messing around with the original Parent Theme?

Solution: You do what I did. I had this exact same problem redesigning ThemeShaper to take advantage of my WordPress Theme Framework, Thematic. I’ll tell you how I solved it and give you a better idea of the power of the functions.php file in WordPress Child Themes.

When you’re done reading this post you should be well on your way to taking full advantage of the power of WordPress Child Themes and redesigning your blog the smart way—leaving the original parent theme files untouched.

And if you haven’t heard about WordPress Child Themes before, make sure you take a look at my post on How To Protect Your WordPress Theme Against Upgrades. I go through a quick primer on them and how to get started using them (along with some useful tips on using Plugins).

First, Make a Functions.php File

Currently, only two overriding files are recognized in WordPress Child Themes, style.css and functions.php (unless my proposal for 2.7 makes it in). You can do a lot with CSS alone but with functions.php your theme can interact with WordPress just like a plugin.

First things first: make a file in your Child Theme folder called functions.php and add the PHP opening and closing tags to the first and second line (<?php and ?>) using your favorite text editor (I use Smultron). Make sure you don’t have any extra lines before or after these tags. We’re going to be inserting the following snippets of code on the lines in-between these tags. Now you’re ready to make your WordPress Child Theme sing.

… not literally, of course. That would be annoying. Continue reading “How I used a WordPress Child Theme To Redesign My Blog”

Problem: You’ve finally found a theme you like but you want to modify it. The modifications are pretty simple but what happens when you want to upgrade the theme? Do you really want to go through all those files again hunting down the changes? Don’t you wish you could just upgrade and be done with it?

I’ve been there. I’ve done everything the wrong way at least twice. Learn from my mistakes. Here’s the right way to modify your theme and protect it against any future upgrades. And don’t worry, it’s really simple. As it usually turns out, WordPress is ready for us and has done most of the heavy lifting.
