# [Plugin: Widget Logic] Use $widget_ID ?

 * I am trying to target a specific widget to append a “all news” link below it’s
   list of recent news posts, titles only.
 * $widget_id is mentioned in the Other Notes for Widget Logic and it seems to be
   the perfect solution. However, there is no example regarding what to DO with 
   the $widget_id variable within a function.
 * so far I have:
 *     ```
       function all_news_link($content='', $widget_id'){
       ?><div>TEST</div><?php
       return $content;
       }
       add_filter('widget_content','all_news_link');
       ```
   
 * I simply want to modify this so that the div with “TEST” in it will only show
   up on this specific widget with the ID=”query-posts-3″

 * it’s a filter function – air gets the HTML to output ($content) and (in this 
   case) the widget ID. all you have to do is modify the $content and return it.
   a bit like the code at the end of [http://wordpress.org/extend/plugins/widget-logic/other_notes/](http://wordpress.org/extend/plugins/widget-logic/other_notes/)
 * something like
 * return $content.”<div>TEST</div>”;
 * will give you the right idea

 * alanft –
 * My “Test” content shows up just fine. BUT it shows in ALL widgets. So, what I
   don’t understand is how the function knows what the $widget_id variable is.
 * Hows does $widget_id get a value (presumably the widget ID “query-posts-3”) assigned
   to it?
 * I’ve played with this for days now with only the ability to append text to every
   widget I’m using. That is why I’m here asking for assistance. I do not know how
   to get the plugin/function to ONLY apply the text “TEST” to the one widget I’m
   targeting.

 * The $widget_id is a string value that represents the CSS style ID for the LI 
   that contains the widget (i.e., `<li id="text-3">widget stuff</li>`
    … in this
   case, $widget_id = “text-3”). It’s not a value to change, but a value that changes
   based on the particular widget being dealt with by WP at a given moment. A good
   example to see it in action is to set up 2-3 widgets in a test site, and place
   the following in your functions.php file:
 *     ```
       add_filter('widget_content', 'my_widget_function', 90, 2);
       function my_widget_function( $content='', $widget_id='') {
           return $content . '<p>This widget\'s style ID = ' . $widget_id . '</p>';
       }
       ```
   
 * So, as you will see, each widget will contain whatever content is already in 
   it AND at the end of each widget’s content will be “This widget’s style ID = 
   <current widget ID>”.
 * HTH.

 * [@squidz](https://wordpress.org/support/users/squidz/), you have to change your
   function. first off get rid of the text that outputs the TEST text every time
   it’s called
 * `?><div>TEST</div><?php`
 * and instead get it to RETURN the text you want, e.g.
 * `return $content."ID=".$widget_id;`
 * which will instead put the widget_id at the end of the widget content. Then you
   can alter it to have conditional changes to what it returns.

 * We worked it out and have it under control now Alan. But it took a bunch of trial
   and error.
 * Widget Logic is**one of the most useful** plugins around and this particular 
   feature can quite powerful too. To allow people that aren’t full-on developers
   to exploit it, including a clear and straightforward example of how to use the
   feature on Widget Logic’s “Other Notes” page would be a wonderful thing.

 * i’ve added a tiny bit extra text in the documentation (not yet updated on wordpress.
   org) that should give people the nudge needed.
