customize_post_value_set WordPress Action Hook

The customize_post_value_set hook is triggered when a WordPress Customizer setting is saved. This hook allows you to modify the value of a Customizer setting before it is saved to the database. This can be useful if you need to perform some validation on the value, or if you need to modify the value before it is stored. The first parameter of the hook is the WP_Customize_Setting object for the setting being saved. The second parameter is the new value of the setting. This hook is similar to the customize_value_set hook, but it is specific to Customizer settings.
