WP_Widget_Form_Customize_Control::active_callback() WordPress Method

The active_callback() method is used to determine whether a widget is active or not. This is useful for widgets that are only meant to be displayed on certain pages or posts. For example, a widget that displays a contact form might only be active on the contact page. The active_callback() method takes two parameters: the $instance and $current_instance. The $instance parameter is an array of all the widget's settings. The $current_instance parameter is an array of the current widget's settings. The active_callback() method returns a boolean value. If the widget is active, the method returns true. If the widget is not active, the method returns false.
