So far I’ve got a form that registers users and stamps the time(); they registered via a $time_added variable into mySQL. They also get an access_type_id assigned to them of 7. I’d like this access_type_id to be 7 for a total of 7 days (1 weeks time), then upon 7 days from registering, the user is then assigned an access_type_id of 1, and is sent to a page stating “your trial period is over.”
Is this possible, can someone help out, I’ve been struggling with this for some time. 
$query = "SELECT max(access_priv_id) from registered_mem";
$rs = mysql_query($query, $db_conn);
$row = mysql_fetch_array($rs, MYSQL_NUM);
$access_priv_id = $row[0] + 1;
$query = "INSERT INTO registered_mem (username, password, email, fname, lname, access_type_id, access_priv_id, date_added) VALUES
('".$required_vars['username']."','".$required_vars['pass1']."','".$required_vars['email']."','".$required_vars['firstname']."','".$required_vars['lastname']."',7, $access_priv_id, '$time_added')";
if(!mysql_query($query, $db_conn)){
$error = true;
$error_msg .= "<li>Database Error, Please come back and try to register at another time (1)</li><br>
";
