[PHP-DB] UPDATE instead of INSERT INTO
I made an application which lets users rate web site content. At the heart of the application is this mySQL query: INSERT INTO `ratings` ( `reference` , `content_type` , `content_reference` , `language` , `ip_address` , `rating_timestamp` , `rating` ) VALUES ( NULL , '$content_type','$content_reference' , '$language', '$ip_address', NOW( ) , '$user_rating' ); I am wondering if there is a way to check if the user has already voted (IE If there is already a matching record with the same content_type, content_reference, language, ip_address values) so all that happens is an UPDATE to the rating field?

INSERT INTO ON DUPLICATE KEY UPDATE is what you're looking for. On 9/5/09, Ron Piggott ron@actsministries.org wrote: I made an application which lets users rate web site content.
