Let Theme Override Our Archive Template

In the last episode, you wrote the code to serve the archive template for the FAQ custom post type from the plugin. Now we need to allow the theme to override. If a developer wants to change the archive, s/he could add an archive-faq.php file to their theme. In that case, you’d want to load their template instead of yours. Give the power to the theme over the plugin for templates.

There are a couple of approaches to accomplishing this feature. You’ll first build a solution with Technique 1 that locates the template, and if not available, it then returns the plugin’s template.

Then in our preferred approach, you’ll use the PHP construct strpos to check if the archive-faq.php is in the parameter that WordPress found.

There are several PHP lessons in this episode as well including:

• What is a falsey state and how does it work?
• How does the strict operator work and why do we use it?
• PHP type juggling (here’s the lab on type juggling too)
• PHP type casting
• How strpos works

I also mention a couple of PHP labs, which you can find here:
