note 95228 added to function.mysql-real-escape-string

You must have a connection via mysql_connect before you can successfully do mysql_real_escape_string. I spent a lot of time on a system that wasn't giving error messages because of the php configuration. If you haven't made a database connection with mysql_connect, mysql_real_escape_string will leave you with mysteriously empty POST variables. In the absence of any error messages being displayed, I was quite lost for a while. The POST vars would be there, but as soon as I ran mysql_real_escape_string on it, they would go empty. Once I put in my connection, everything went smoothly. ---- Server IP: 192.41.40.227 Probable Submitter: 98.191.116.203 ---- Manual Page -- http://www.php.net/manual/en/function.mysql-real-escape-string.php Edit -- https://master.php.net/note/edit/95228 Del: integrated -- https://master.php.net/note/delete/95228/integrated Del: useless -- https://master.php.net/note/delete/95228/useless Del: bad code -- https://master.php.net/note/delete/95228/bad+code Del: spam -- https://master.php.net/note/delete/95228/spam Del: non-english -- https://master.php.net/note/delete/95228/non-english Del: in docs -- https://master.php.net/note/delete/95228/in+docs Del: other reasons-- https://master.php.net/note/delete/95228 Reject -- https://master.php.net/note/reject/95228 Search -- https://master.php.net/manage/user-notes.php
