   Hi - I am using the following to generate a list of posts that have certain tags:

   $query = array('cat' => '4', 'orderby' => 'rand', 'tag__in' => array(7,9))

   This works great.

   The problem is that I can't seem to generate the array for tag__in dynamically. If I use an array of values ( 'tag__in' => $array )it always outputs thus:

   [tag__and] => Array ( [0] => 7,9 )

   But the query wants only values separated by commas. Because of this it only recognizes the first tag.

   So how do I make an array only output comma separated values without keys? (PS I tried implode() and got the same result).

   Thanks!

   Here's how I got it working:

   $tags = '1,2,3';
   $tags = explode(',',$tags);
   $post_query = array('cat' => '4', 'orderby' => 'rand', 'tag__in' => $tags );
   query_posts($post_query);

   Here's what $post_query looks like:

   Array ( [cat] => 4 [orderby] => rand [tag__in] => Array ( [0] => 7 [1] => 9 ) )

   Maybe it will help someone.
