   Hi All

   Maybe somebody can help me here?
   I've been trying to do this for days now with no success.
   I'm trying to use the "in_mediatag()" function to add a class, but just not getting it right. There don't seem to be any examples on the site. I'd like to use it in a function that was shown at http://digwp.com/2009/08/awesome-image-attachment-recipes-for-wordpress/

   This is what I'm trying:
   

   if (in_mediatag('choice')){
   echo ' my-choice-item';
   }

   In context:
   

   function gallery_toolbox($size = thumbnail) {
   
   	if($images = get_children(array(
       'order' => 'ASC',
   		'orderby' => 'menu_order',
   		'post_parent'    => get_the_ID(),
   		'post_type'      => 'attachment',
   		'numberposts'    => -1, // display the amount to show per post
   		'post_status'    => null,
   		'post_mime_type' => 'image',
   	))) {
   		foreach($images as $image) {
   			$attimg   = wp_get_attachment_image($image->ID,$size);
   			$atturl   = wp_get_attachment_url($image->ID);
   			$attlink  = get_attachment_link($image->ID);
   			$atttitle = apply_filters('the_title',$image->post_title);
   			$postlink = get_permalink($image->post_parent);
   			$posttitle= get_the_title($image->post_parent);
   
   			echo '<dl class="gallery-item';
   			if (in_mediatag('choice')){
   			echo ' my-choice-item';
   			}
   			echo '"><dt class="gallery-icon"><a href='.$attlink.' >'.$attimg.'</a></dt><dd class="gallery-caption"><a href='.$attlink.'>'.$atttitle.'</a></dd></dl>';
   
   		}
   	}
   }

   I cannot figure out what the equivalent function to has_tag() would be.

   triggame,

   I was hoping WP core would come up with a generic function like has_tag which would work for other Taxonomies. Since Media-Tags uses the new Taxonomy system I've cloned the has_tag WP function to has_mediatag()

   So instead of calling in_mediatag('choice') use has-mediatag('choice', $image->ID);

   Note you do need to provided the second parameter since has_tag assumed you are working with the global $post object by default.

   function has_mediatag( $tag = '', $_post = null ) {

   if ( $_post ) {
   $_post = get_post( $_post );
   }
   else {
   $_post =& $GLOBALS['post'];
   }
   if ( !$_post )
   return false;

   $r = is_object_in_term( $_post->ID, MEDIA_TAGS_TAXONOMY, $tag );

   if ( is_wp_error( $r ) )
   return false;
   return $r;
   }

   THANK YOU, THANK YOU, THANK YOU!!!!!!!!!!!!!!!!!!!
   You have absolutely no idea how glad I am!

   No clue what you did with the second parameter bit, but I just pasted it inside my functions.php file and it worked perfectly!

   Thanks so much Paul! ...and thanks for getting back to me so quickly.

   John.

   You are very welcome. Thank you for using my Media-Tags plugin. One other note. I'm including the function has_mediatag into the upcoming 3.0 release of the plugin. So as not to conflict with your version in your theme's functions.php can you give your local function a different name.
