WordPress Widget Boilerplate

Here is a WordPress snippet to create your own WordPress Widgets.

A Widget is a piece of PHP Code which will run when it is placed inside a Sidebar. A good example of a widget is data displayed in the sidebar of a blog. Like this blog I use widgets to display the Google badge, Twitter Feed and Facebook like box.

Having these as Widgets mean I can place them in multiple places of the WordPress theme directly in the WordPress dashboard. You can create a WordPress widget to do anything you want, the easiest way to create a WordPress widget is to inherit the WP_Widget class. This way you can use the inbuilt functions to update the widget, display the widget and create an admin page for the widget.

Below is the boilerplate of a WordPress widget, when you create a new widget just copy and paste the below code as a starting point for your Widget.

/** * Adds Foo_Widget widget. */ class Foo_Widget extends WP_Widget {

/** * Register widget with WordPress. */ public function __construct() { parent::__construct( 'foo_widget', // Base ID 'Foo_Widget', // Name array( 'description' => __( 'A Foo Widget', 'text_domain' ), ) // Args ); }

/** * Front-end display of widget. * * @see WP_Widget::widget() * * @param array $args Widget arguments. * @param array $instance Saved values from database. */ public function widget( $args, $instance ) { extract( $args ); $title = apply_filters( 'widget_title', $instance['title'] );

echo $before_widget; if ( ! empty( $title ) ) echo $before_title . $title . $after_title; ?>Hello, World!
