How to use content_pagination filter in WordPress

In WordPress development, hooks are like magic spells that let you customize the core functionality of your site without touching the core files. One such handy hook is the content_pagination filter. Let’s dive into how you can use this hook in your WordPress theme or plugin.

Example 1: Modifying Content Pagination Defaults

Here’s how you can tweak the default behavior of the content_pagination filter. Just register it using add_filter in your theme’s functions.php or a custom plugin:

function weplugins_modify_content_pagination_defaults($pages, $post) { 
    // Update the $pages variable according to your website requirements and return this variable.
    return $pages; 
}
// Add the filter
add_filter("content_pagination", "weplugins_modify_content_pagination_defaults", 10, 2);

Example 2: Conditional Pagination Modification

Sometimes, you might want to modify pagination based on certain conditions, like post type or category. Here’s a quick example of how you can achieve this:

function weplugins_conditional_content_pagination($pages, $post) { 
    if ($post->post_type == 'custom_post_type') {
        // Modify $pages for specific post type
    }
    return $pages; 
}
// Add the filter
add_filter("content_pagination", "weplugins_conditional_content_pagination", 10, 2);

Example 3: Removing Content Pagination Filter

If you ever need to remove a previously registered filter, use remove_filter. Remember to provide the same callback function name, priority, and number of arguments:

remove_filter("content_pagination", "weplugins_modify_content_pagination_defaults", 10, 2);

Parameters

• $pages: (string[]) Array of “pages” from the post content split by <!-- nextpage --> tags.
• $post: (WP_Post) Current post object.
