If you’re working on a WordPress project and facing trouble with the next_posts_link() and previous_posts_link() functions while using the Posts 2 Posts plugin, don’t worry; you’re not alone. Many WordPress developers encounter this issue, but the solution is within reach. In this step-by-step guide, we’ll walk you through fixing these problems in simple terms.

Understanding the Problem

The original poster is utilizing the Posts 2 Posts plugin to display posts from one post type to another. Everything seems to be working well, except for the navigation links (next_posts_link() and previous_posts_link()), which aren’t showing up as expected. The user has specified the paged variable in the code, but the issue persists.

Step 1: Check the Codex Page

In the discussion, another user suggests checking the Codex page for next_posts_link. This is a good starting point. The Codex provides valuable information on using next_posts_link() with WP_Query.

Step 2: Implementing the Solution

The key insight from the Codex is to add the $max_pages parameter to the next_posts_link() function when using WP_Query. Here’s how you can modify the code:

Replace the existing next_posts_link() code with the following:

next_posts_link( 'Next →', $connected->max_num_pages );

This modification ensures that the correct number of pages is used for navigation.

Step 3: Clarifying page and paged

A helpful comment in the discussion points out that page and paged are not the same. It also mentions that if you don’t pass max_num_pages, it might use the value from an entirely different query.

Double-check your code to ensure that the paged variable is correctly implemented and that you pass the max_num_pages parameter as shown in Step 2.

Step 4: Troubleshooting

If the problem persists, try the following:


By following these steps, you should be able to resolve the issue with next_posts_link() and previous_posts_link() not showing up in your WordPress project using the Posts 2 Posts plugin. Remember to carefully implement the modifications and double-check your code for any discrepancies. Happy coding!
