I am working on a classifieds script which I have brought and adapting to my needs, from which I have done alot of! One thing that I can not fix on it is to run a check to see if a advert has allready recieved a feedback rating Here is what infomation is passed from the form to the php : // Get Values $comment $detailed $type $rating $ratedid $ratedusername $adid $raterid $dateline $ratedusername Now each advert has a id ($adid) and at most it should have 2 feedbacks linked to it, for both the buyer and seller. Since the buyer and seller will have different ratedid (or raterid)'s I need to constuct a mysql querie that will check the database to see if there is allready feedback listed for the adid and if so if its for either the buyer or seller, if it is then i can then spit out a error message (database is trading.ratings colums are the same as the entries the form spits out) My problem is I have zero mysql knowledge and ive tried messing around with some other quieries in the script but to no joy Any help is very welcome, or a point in the right direction, most of the google searchs I did came up wiht 1 to 5 style rating systems etc
