This is what we have in the Tag model for Cheesecake
function findRelatedTags($tags=array()){
$prefix = $this->tablePrefix;
$tagsCount = count($tags);
if($tagsCount > 0){
$tagsString = "'".implode("','",$tags)."'";
$query = "SELECT Tags.*, COUNT(pt.photo_id) AS count
FROM {$prefix}photos_tags pt, {$prefix}tags
Tags
WHERE pt.photo_id IN (
SELECT pt.photo_id FROM
{$prefix}photos_tags pt, {$prefix}tags Tags
WHERE pt.tag_id = Tags.id
AND Tags.tag IN
({$tagsString})
GROUP BY pt.photo_id
HAVING COUNT(pt.photo_id
)={$tagsCount})
AND Tags.tag NOT IN ({$tagsString})
AND Tags.id = pt.tag_id
GROUP BY pt.tag_id
ORDER BY count DESC";
$relatedTags = $this->query($query);
return $relatedTags;
}
You can of course make it more generic but that was not needed in our case
