birbal 168 Report post Posted July 14, 2012 (edited) You dont need to send a query(reduce overhead) if you have any PK or unique constraint in your database table. if your database schema wants any unique column you should constraint it from the database. you can directly execute the INSERT, if there is no any duplication it will get inserted. otherwise when it fails it sends error, you check the specific error number using mysql_errno() and you can show any specific custom error on that. you can check list of mysql error number here ==> http://dev.mysql.com...ges-server.htmlhttp://php.net/mysql_errno Edited July 14, 2012 by birbal Quote Share this post Link to post Share on other sites
