It’s hard to tell the order in which these functions are called, because they’re used in different contexts. WP_Widget class has 4 methods: __construct – it constructs the widget, so it’s always run first widget – it should output the content of given widget, so it’s used on front-end in sidebar, when the widget is … Read more
