Automate WP_Query Tag Retrieval Based on Prefixes in WordPress

Are you looking to streamline your WordPress website by automatically retrieving tags based on specific prefixes? If you find yourself manually entering numerous tags into your WP_Query, this guide is for you! We'll explore how to create a more efficient workflow by building a dynamic list of tags that begin with defined letters and then seamlessly incorporate them into your WP_Query.

The Challenge: Manual Tag Management

Managing tags manually can be a cumbersome process, especially when you're dealing with a large number of them. Imagine having to type out 256 possible tags with the prefix "sim-" each time you create a new query. This can be tedious and prone to errors. Thus, automating this process not only saves time but also improves accuracy.

The Solution: Dynamic Tag Retrieval

In this guide, we will walk through how to dynamically build a list of tags that meet specific criteria and use that list to create an array for your WP_Query.

Step-by-Step Implementation

Retrieve Tags from the Current Post

Start by using the wp_get_post_tags() function to get all the tags for your current post. This will return an array of tag objects.

Initialize an Array for Your Tags

Create an empty array that will hold the tags that meet your criteria.

Filter Tags Based on the Prefix

Loop through each tag and check if its slug starts with "sim-". If it does, add it to your array.

Add Additional Tags as Necessary

If you want to include other tags, such as "blankcategory", simply append those to your tag array.
