Hi I'm new to PHP/MySQL and wondered if anyone on this list would be kind enough to help me solve this problem. I'm trying to automatically set up a users privileges on a MySQL table using the username and password selected by them in an html form. I get the error message: "Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource" for the code below: <?php $username=$_POST['username']; $password=$_POST['password']; @ $db = new mysqli('localhost', 'root', 'password', 'database_table'); if (mysqli_connect_errno()) { echo 'Error: Could not connect to database. Please try again later.'; exit; } $grant_privilege = "grant select, insert, delete, update on name_of_table to $username identified by '$password'"; mysql_query($grant_privilege, $db); $db->close(); ?> Can anyone help?
