How to use customize_previewable_devices filter in WordPress

Alright, let’s dive into the world of WordPress hooks, specifically the customize_previewable_devices filter. As a fellow developer, I can tell you this: hooks are like the secret sauce that makes WordPress so customizable. This filter lets you tweak the devices previewed in the customizer, which is pretty neat if you’re looking to tailor the experience for different screen sizes.

To use the customize_previewable_devices filter, you’ll first need to register it using add_filter. This can be done in the functions.php file of your active theme or, even better, in a custom WordPress plugin. At WePlugins, we always recommend creating a custom plugin for this to prevent any issues during theme updates.

Here’s how you can leverage this hook with a few practical examples:

Example 1: Modify Previewable Devices Defaults

In this example, we’re defining a function weplugins_modify_customize_previewable_devices_defaults that adjusts the default devices previewed in the customizer.

    function weplugins_modify_customize_previewable_devices_defaults($devices) { 
        // Update the $devices variable according to your website requirements.
        return $devices; 
    }
    // Add the filter
    add_filter("customize_previewable_devices", "weplugins_modify_customize_previewable_devices_defaults", 10, 1);
    

Example 2: Removing a Hook Callback

If there’s ever a need to remove a previously registered hook, you can do so using remove_filter. Just ensure you provide the same callback function, priority, and number of arguments.

    remove_filter("customize_previewable_devices", "weplugins_modify_customize_previewable_devices_defaults", 10, 1);
    

Example 3: Conditional Device Customization

You can also modify the devices array conditionally, allowing for a more dynamic approach depending on specific criteria or conditions within your site.

    function weplugins_conditional_customize_previewable_devices($devices) { 
        if (/* some condition */) {
            // Modify $devices accordingly
        }
        return $devices; 
    }
    // Add the filter
    add_filter("customize_previewable_devices", "weplugins_conditional_customize_previewable_devices", 10, 1);
