How to use customize_partial_render filter in WordPress

So, you’re diving into WordPress hooks, huh? Let’s talk about the customize_partial_render filter. This hook is quite handy when you want to filter partial rendering in WordPress. To get started, you need to register it using add_filter. You can do this in your theme’s functions.php file or better yet, create a custom WordPress plugin. Trust me, creating a plugin is a good practice because when you update your theme, nothing breaks!

Example 1: Modify Rendered Output

In this example, we’ll see how to modify the rendered output using the customize_partial_render filter.

    function weplugins_modify_customize_partial_render_defaults($rendered, $partial, $container_context) { 
        // Update the $rendered variable according to your website requirements and return this variable.
        return $rendered; 
    }
    // Add the filter
    add_filter("customize_partial_render", "weplugins_modify_customize_partial_render_defaults", 10, 3);
    

Example 2: Remove a Hook Callback

Sometimes, you might need to remove a registered hook. Here’s how you can use remove_filter to do that for the customize_partial_render filter.

    remove_filter("customize_partial_render", "weplugins_modify_customize_partial_render_defaults", 10, 3);
    

Remember, you must provide the same callback function name, priority, and number of arguments when removing the hook callback.

Example 3: Customizing Based on Conditions

You can also customize the rendered output conditionally. This allows more flexibility in how you display content.

    function weplugins_conditional_customize_partial_render($rendered, $partial, $container_context) { 
        if ($partial->id == 'special_case') {
            // Customize for the special case
            $rendered = 'Special Case Rendered Content';
        }
        return $rendered; 
    }
    // Add the filter
    add_filter("customize_partial_render", "weplugins_conditional_customize_partial_render", 10, 3);
