The widgets_init Hook in WPFTS

The widgets_init hook is a standard WordPress hook that is called when widgets are initialized. WPFTS uses this hook to register its search widget – WPFTS :: Live Search.

What WPFTS Does When widgets_init is Called:

1. Widget Registration: The plugin registers the WPFTS_Custom_Widget class, which is responsible for the functionality of the search widget. This allows users to add the WPFTS search widget to their site via the “Widgets” section in the admin panel.

Important Functions Involved in Handling widgets_init:

• register_widget('WPFTS_Custom_Widget')

How to Use This in Addon Development:

Addon developers usually don’t need to interact with this hook directly unless they are creating their own widgets integrated with WPFTS. If you are creating your own widget, you can use this hook to register it, similar to how WPFTS does it.

Additional Notes:

• The WPFTS :: Live Search widget provides users with the ability to perform searches using WPFTS on the site’s frontend.
• Widget settings, such as the title, placeholder, and others, can be modified through the admin panel.
• The widget’s HTML code can be modified using the wpfts_widget_html filter.

This hook demonstrates how WPFTS registers its search widget, which can be a useful example for addon developers.
