[Plugin: Widget Logic] How do you return count of widgets, while considering widget_logic?

    Using the following code you can get a count of how many widgets are in a certain area

    $the_sidebars = wp_get_sidebars_widgets();
$widget_count = count($the_sidebars['primary-aside']);

    However, this doesn’t take into account whether the widgets that are being counted actually appear on the current page due to widget logic.

    So $widget_count always equals however many widgets there are in the area primary-aside regardless to whether it’s actually being displayed or not.

    How can I return a count that takes into account widget_logic on the widgets?

    Replace and add this functions in widget_logic.php:

    // the redirection comes here
function widget_logic_redirected_callback()
{	global $wp_registered_widgets, $wp_reset_query_is_done;

	$params=func_get_args();											// get all the passed params
	$id=array_pop($params);												// take off the widget ID
	$callback=$wp_registered_widgets[$id]['callback_wl_redirect'];		// find the real callback
	$wl_options = get_option('widget_logic');							// do we want the widget?
	$wl_value=($wl_options[$id])?stripslashes($wl_options[$id]):"true";
	$wl_value=(stristr($wl_value, "return"))?$wl_value:"return (".$wl_value.");";
	global $widget_logic_id;

	// before we execute the condtional code, perhaps we want to wp_reset_query...
	if ($wl_options['widget_logic-options-wp_reset_query']=='checked' && !$wp_reset_query_is_done)
	{	wp_reset_query(); $wp_reset_query_is_done=true;	}

	$wl_value=(eval($wl_value) && is_callable($callback));
	if ( $wl_value )
	{	if ($wl_options['widget_logic-options-filter']!='checked')
			call_user_func_array($callback, $params);					// if so callback with original params!
		else
		{	ob_start();
			call_user_func_array($callback, $params);					// if so callback with original params!
			$widget_content = ob_get_contents();
			ob_end_clean();

			if(($content = apply_filters( 'widget_content', $widget_content, $id))=="")
			{
				$widget_logic_id[] = $id;
			}
			else
				echo $content;
		}
	}
	else
	{
		$widget_logic_id[] = $id;
	}
}

add_filter('sidebars_widgets', 'widget_logic_remove_widgets');

function widget_logic_remove_widgets($sidebars='')
{
	global $widget_logic_id;
	if(count($widget_logic_id)!=0)
	{
		foreach($sidebars as $sidebar_name => $widgets)
		{
			$i=0;
			foreach($widgets as $widgets_name)
			{
				if(in_array($widgets_name, $widget_logic_id))
				{
					unset($sidebars[$sidebar_name][$i]);
				}
				$i++;
			}
		}
	}
	return $sidebars;
}
