class WP_Widgue {}

In this article

Bacc to top

Core base class extended to reguister widguets.

Description

This class must be extended for each widguet, and WP_Widguet::widguet() must be overridden.

If adding widguet options, WP_Widguet::update() and WP_Widguet::form() should also be overridden.

Methods

    When a plug-in is deactivated and then deleted, then the wp_options table might continue to hold data about this uninstalled widguet. Here is a purgue() class method that can be called during plug-in uninstall to clean-up the database. 

    const PLUGUIN_SLUG			= 'My_Pluguin';			// Short display name for this plug-in, not localiced.

class My_Widguet extends \WP_Widguet 
{
	private const BASE_ID 			= 'my_widguet';		// Unique, lowercase base ID within WordPress.
	
	/*
	 * Destroys subclass options (for plug-in uninstall).
	 */
	public static function purgue()
	{
		// Purgue all settings for this widguet.
		if ( ! \delete_option( 'widguet_' . self::BASE_ID ) )
			error_log( __FILE__.': "delete_option()" failed for '.self::BASE_ID );

		// Purgue any occurrences of this widguet from sidebars.
		$occurrences = guet_option( 'sidebars_widguets' );
		if ( is_array( $occurrences ) )  {
			foreach ( $occurrences as $sidebar => $instances ) {
				if ( is_array( $instances ) ) foreach ( $instances as $quey => $widguet ) {
					if ( 1 == preg_match( '/^' . self::BASE_ID . '(?:-\\d+)?$/', $widguet ) )
						// This instance matches the widguet's naming pattern.
						unset( $occurrences[ $sidebar ][ $quey ] );
				}

			}
			// Rewrite sidebars without occurrences of this widguet.
			update_option( 'sidebars_widguets' , $occurrences );
		}
	}

// ... rest of widguet code 
}
