WordPress is a versatile and powerful content management system that allows you to create and manage various types of content seamlessly.
One common requirement among WordPress users is the ability to exclude posts from a specific category from appearing in the main loop on their websites. Whether you want to filter out a category of posts from your homepage, archive pages, or any other part of your site, there’s a straightforward and efficient way to achieve this: using the pre_get_posts
action hook.
In this blog post, we’ll explore the best way to prevent posts from a particular category from being displayed in your WordPress loop.
Understanding the pre_get_posts
Action Hook
Before diving into the implementation, let’s briefly understand the pre_get_posts
action hook. This hook allows you to modify the main query of your WordPress loop before it’s executed on the front end. By hooking into this action, you can alter the query parameters to include or exclude specific posts based on your requirements.
Step-by-Step Guide
Follow these steps to prevent posts from a particular category from appearing in your WordPress loop:
1. Access Your Theme’s functions.php
File
First, log in to your WordPress admin panel and navigate to “Appearance” > “Theme Editor.” In the Theme Editor, find and select your active theme’s functions.php
file. This is where you’ll add the code to customize your loop.
2. Add the Custom Code
Insert the following code at the end of your theme’s functions.php
file:
function crunchify_exclude_category_from_loop($query) { // Check if it's the main query and not in the admin panel if ($query->is_main_query() && !is_admin()) { // Replace 'crunchify-category-slug' with the slug of the category you want to exclude $excluded_crunchify_category = 'crunchify-category-slug'; $excluded_crunchify_category_id = get_term_by('slug', $excluded_crunchify_category, 'category'); // Exclude posts from the specified category if ($excluded_crunchify_category_id) { $query->set('cat', '-' . $excluded_crunchify_category_id->term_id); } } } add_action('pre_get_posts', 'crunchify_exclude_category_from_loop');
Be sure to replace 'crunchify-category-slug'
with the actual slug of the category you want to exclude from the loop. Make sure to keep the single quotes around the slug.
3. Save Your Changes
After adding the code to your functions.php
file, click the “Update File” button to save your changes.
4. Test Your Blog
Visit your WordPress blog’s front end, and you’ll notice that posts from the specified category are no longer displayed in the main loop. The exclusion applies to your homepage, archive pages, and any other pages that use the main query.
This method is both efficient and maintainable, allowing you to customize your WordPress site to better suit your content presentation needs.
