How to use posts_where_paged filter in WordPress

Example 1: Basic Usage of posts_where_paged

This example demonstrates how to use the posts_where_paged filter to modify the WHERE clause of a query.

    function weplugins_modify_posts_where_paged_defaults($where, $query) { 
        // Update the $where variable according to your website requirements 
        return $where; 
    }
    // add the filter
    add_filter( "posts_where_paged", "weplugins_modify_posts_where_paged_defaults", 10, 2 );
    

Example 2: Conditional Modification

In this example, we conditionally modify the $where clause based on custom logic.

    function weplugins_conditional_posts_where_paged($where, $query) {
        if ($query->is_main_query() && !is_admin()) {
            // Modify the $where variable conditionally
        }
        return $where;
    }
    add_filter( "posts_where_paged", "weplugins_conditional_posts_where_paged", 10, 2 );
    

Example 3: Removing the Hook

Sometimes, you may need to remove a previously registered hook. Here’s how you can do it.

    remove_filter( "posts_where_paged", "weplugins_modify_posts_where_paged_defaults", 10, 2 );
    

Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.
