# shortcode attribute default value post->ID

 * I have a shortcode `[user-profile]` where the author ID is the attribute. I’d
   like to make it so that if no ID is specified `[user-profile]` defaults to post
   author, and when an ID _is_ specified, like `[user-profile id="47"]`, it uses
   that ID. The shortcode function right now is like this:
 *     ```
       function user_profile( $atts, $content = null ) {
       	extract(shortcode_atts(array('id' => ''), $atts));
       	include ('user-profile.php');
       	return $user_hcard;
       	}
       ```
   
 * …which works only when an ID is specified.
    ([user-profile.php code is here](http://dev.airve.com/code/user-profile_20110606.txt))
   How can I set the default to be the $post->ID ?

 * Of course 🙂
    I already tried
 *     ```
       extract(shortcode_atts(array('id' => $post->ID), $atts));
       ```
   
 * but no dice.

 * as this is in functions.php, you may need to use `global $post` right at the 
   beginning of the function.

       	include ('user-profile.php');
       	return $user_hcard;
