[wp-hackers] Identify the sidebar from within a widget?

[Dagan Henderson]

Building on Otto's reply, here is an example of $args: 

$args	Array [9]	
	name	(string:15) Primary Sidebar	
	id	(string:9) sidebar-1	
	description	(string:66) A widget area displayed on the right side of most pages/templates.	
	before_widget	(string:61) <li id="recent-posts-3" class="widget widget_recent_entries">	
	after_widget	(string:6) </li>\n	
	before_title	(string:25) <h1 class="widget-title">	
	after_title	(string:5) </h1>	
	widget_id	(string:14) recent-posts-3	
	widget_name	(string:12) Recent Posts

If you're using a standard widget class inheriting from WP_Widget, then the widget($args, $instance) function which displays the widget receives $args as its first parameter.

$args contains info about what sidebar you're in. Specifically, $args['name'] and $args['id'] refer to the sidebar's name and id.


Demo:

class New_Widget extends WP_Widget {
	function New_Widget() {
		$widget_ops = array('classname' => 'widget_new-widget', 'description' => 'New Widget');
		$this->WP_Widget('new-widget', 'New Widget', $widget_ops);
	}

	function widget($args, $instance) {
		var_dump($args);
	}

	function update($new_instance, $old_instance) {
		return $new_instance;
	}

	function form($instance) {
	}
}
add_action('widgets_init', create_function('', 'return register_widget("New_Widget");'));


Look at what the widget dumps for output.
