How to use debug_information filter in WordPress

Introduction to debug_information Filter

When you’re working with WordPress, sometimes you might want to add your own debug information to your site without having to create extra admin pages. The debug_information filter is perfect for this! It’s a handy tool that allows plugins or themes to introduce their own sections or enhance existing ones. To use it, you’ll first need to register it using add_filter. You can do this in your theme’s functions.php file or in a custom WordPress plugin. At WePlugins, we always recommend creating a custom plugin for hooks. This way, if you update your WordPress theme, nothing breaks. Also, if you ever need to remove a registered hook, you can use remove_filter.

Example 1: Basic Usage

Here’s a straightforward example of using the debug_information filter. This code snippet shows how to modify debug information.

    function weplugins_modify_debug_information_defaults($args) { 
        // Update the $args variable according to your website requirements and return this variable.
        return $args; 
    }
    // Register the filter
    add_filter("debug_information", "weplugins_modify_debug_information_defaults", 10, 1);
    

Example 2: Removing a Hook

If you need to remove a previously registered hook callback, here’s how you can do it. Make sure to provide the same callback function name, priority, and number of arguments.

    remove_filter("debug_information", "weplugins_modify_debug_information_defaults", 10, 1);
    

Example 3: Conditional Modifications

You can also modify the $args variable conditionally. This example shows how you can change the debug information based on certain conditions.

    function weplugins_modify_debug_information_conditionally($args) { 
        if (is_user_logged_in()) {
            // Modify $args for logged-in users
        } else {
            // Modify $args for guest users
        }
        return $args;
    }
    add_filter("debug_information", "weplugins_modify_debug_information_conditionally", 10, 1);
