How to use customize_sanitize_this-id filter in WordPress

Welcome to the world of WordPress hooks, my friend! If you’re diving into the world of WordPress customization, then the customize_sanitize_this-id filter is something you should definitely know about. This filter is a powerful tool for filtering a Customize setting value in un-slashed form. Now, let’s get into how you can use it effectively.

Understanding customize_sanitize_this-id Filter

First things first, to use the customize_sanitize_this-id filter, you need to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin. It’s always a good practice to create a custom WordPress Plugin while using hooks, so nothing breaks when you update your WordPress Theme in the future.

Parameters

Below are the 2 parameters required to use this hook:

• $value: (mixed) Value of the setting.
• $setting: (WP_Customize_Setting) WP_Customize_Setting instance.

Example 1: Applying the Filter

Here’s a live example of how you can use this hook:

    function weplugins_modify_customize_sanitize_this-id_defaults($value, $setting) { 
        // Update the $value variable according to your website requirements and return it.
        return $value; 
    }
    // add the filter
    add_filter( "customize_sanitize_this-id", "weplugins_modify_customize_sanitize_this-id_defaults", 10, 2 );
    

Example 2: Removing the Filter

Sometimes, you have to remove a registered hook. Use the example below to remove the customize_sanitize_this-id filter:

    remove_filter( "customize_sanitize_this-id", "weplugins_modify_customize_sanitize_this-id_defaults", 10, 2 );
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Conditional Modifications

You can modify the $value variable conditionally too, if you want to handle different scenarios:

    function weplugins_modify_customize_sanitize_this-id_conditionally($value, $setting) {
        if ($setting->id === 'specific_setting_id') {
            $value = 'modified_value';
        }
        return $value;
    }
    add_filter( "customize_sanitize_this-id", "weplugins_modify_customize_sanitize_this-id_conditionally", 10, 2 );
