Mysql_escape_string($row[USER_TABLE_FIRST]) . "', " . USER_TABLE_LAST . "='" . mysql_escape_string($row[USER_TABLE_LAST]) . "', " . USER_TABLE_SIGN . "='" . mysql_escape_string($row[USER_TABLE_SIGN]) . "'"; $result = $this->db->query($sql); if ($result->isError()) { return FALSE; } else { // Delete row from signup table $sql = "DELETE FROM " . SIGNUP_TABLE . " WHERE " . SIGNUP_TABLE_ID . "='" . $row[SIGNUP_TABLE_ID] . "'"; $this->db->query($sql); return TRUE; } } else { return FALSE; } } } If an account is successfully confirmed, the row is copied to the user table (note that I had to re-escape the values stored in the signup table in case they contained SQL injections that were escaped when originally inserted), and the old row in the signup table is deleted.

Be very careful that you don’t create a hole in your security, though. If you’re not checking for existing records in the user table, a user could sign up for a new account with details that matched an existing row in the user table. You’ll then end up changing the email address of an existing user to that of a new user, which will cause some embarrassing moments at the very least. How do I protect my site from auto sign ups? I hope you’ll never suffer the misfortune of having someone try to put your site out of action, but when you expose your application to what is, after all, a global network, you need to be prepared for trouble.
