WordPress Complete - Sixth Edition

Initiating and hooking up the widget

That's it for widget functionality! Now, you just need to add a little piece of code that will hook the widget up to the rest of WordPress:

function KK_Widget_Tag_Cloud_Reg() { 
  register_widget('KK_Widget_Tag_Cloud'); 
} 
add_action('widgets_init', 'KK_Widget_Tag_Cloud_Reg');

This tells WordPress that when it initiates widgets, it should be sure to register our new widget.

This version of the widget is available in the code bundle for this chapter--inside a subfolder labeled phase 1. We'll still be adding one more feature before we can call it the final version.
