# Bug in tag clouds?

 * I’m trying to hack around with WP 2.3 to add support for its tags to my theme(
   I previously used UTW). I want a dropdown menu of all tags, sorted alphabetically.
 * It seems that I should be able to use wp_tag_cloud(‘format=array’) to build on,
   but this **echos** the array, it does not **return** it, making it impossible
   to manipulate, or even display properly.
 * I’ve been doing some messing around with a tweaked version of this function, 
   but have not succeeded in returning a usable array.
 * thanks in advance for any advice.

 * I’ve tried also format=array trying to help you out with the problem …it is correct:
   It just returns “array” text not the tags.

 * This seems to be still relevant, so here is the solution:
 * in wp-includes/category-template.php the function wp_tag_cloud echos the return
   value, which makes sense if it’s a HTML string but not if it’s an array.
 * So if you replace
 *     ```
       if ( is_wp_error( $return ) )
       		return false;
       	else
       		echo apply_filters( 'wp_tag_cloud', $return, $args );
       ```
   
 * with
 *     ```
       if ( is_wp_error( $return ) )
       		return false;
       	else if (is_array($return)) {
       	 return $return;
       	} else {
       		echo apply_filters( 'wp_tag_cloud', $return, $args );
       	}
       }
       ```
   
 * (line 234ff) to check if the return value is an array then the array-option works.

 * Known issue:
    [http://trac.wordpress.org/ticket/5155](http://trac.wordpress.org/ticket/5155)
 * A patch is in that ticket to fix the problem. Hopefully it’ll make it into 2.5.
