revraz Posted January 6, 2009 Share Posted January 6, 2009 The URL is not setting $id because you are not using $_GET to retrieve it. $id=$_GET["id"]; Link to comment https://forums.phpfreaks.com/topic/139643-update-mysql-database-script/#findComment-730979 Share on other sites More sharing options...
