Ben: First, using a $_POST value directly into a MySQL query is EXTREMELY unsafe. Always filter data from any source to make sure it's what you expect. SQL injection is one of the easiest ways to cause real damage to a website. http://en.wikipedia.org/wiki/SQL_injection Check out this fuction for making the string safe: http://us2.php.net/manual/en/function.mysql-real-escape-string.php Also, try and strip out any characters that don't belong in the string anyway, just as added security. Good luck learning PHP. --Another person who happens to be named Ben I've also put a few edits in the code.
