Creating a simple widget in WordPress

We have a standard format in WP for creating a simple WordPress widget .

1. You need to create a Class Which Extends Wp_Widget .

   class YOURPLUGINNAME extends WP_Widget {
   .....
   ...
   }
   

2. There are some predefined methods to be used in php .
   1. widget method : The code or content written in it is displayed in front-end , this method looks like ..

      function widget($args, $instance) {
      }
      

3. The Simple widget Class looks like this .

   
   class YOURPLUGINNAME extends WP_Widget {
   	/** constructor */
   	function YOURPLUGINNAME() {
                    $widget_ops = array (
   			'description' => __('Description of the widget goes here')
   		);
   		parent :: WP_Widget(false, $name = 'Name of the widget', $widget_ops);
   	}
   
   	/** @see WP_Widget::widget */
   	function widget($args, $instance) {
   
   	}
   
   	/** @see WP_Widget::update */
   	function update($new_instance, $old_instance) {
   		$instance = $old_instance;
   		$instance['title'] = strip_tags($new_instance['title']);
   		$instance['email'] = strip_tags($new_instance['email']);
   		$instance['from'] = strip_tags($new_instance['from']);
   		return $instance;
   	}
   
   	/** @see WP_Widget::form */
   	function form($instance) {
   
   	}
   }
   

4. Finally you need to register the Class for widget creation .

   
   add_action('widgets_init', create_function('', 'return register_widget("YOURPLUGINNAME");'));
