Welcome to the series finale of "The Tuts+ Guide to Template Tags"! It's been a long but great journey, as I said it would be in the first part. And in this last post, we're going to review what we've learned and conclude the series.

First Part

In the first part of the series, we introduced the concept of "template tags" in WordPress: We saw:

1. What template tags are
2. Where they are
3. How are the functions made
4. How to use the functions

As I stated a couple of times, template tags are one of the most important and one of the easiest WordPress concepts to learn about. It's only a matter of memorizing the functions and their parameters, just as we need to memorize many PHP functions while learning PHP.

Middle Parts

In the middle parts of the series, we reviewed almost 200 template tags, which are documented in the Codex. Of course, there are many more (maybe twice as more) template tags out there in the core of WordPress, and it would be another journey to review them.

I split the template tags into categorized "batches" to make it easier to learn the template tags in each part. In the first batch, we reviewed template tags about "post data":
