Question

I have the following table in the database:

id, username, email, old_ip, current_ip

Everytime the user logs in, I want their current ip to be stored in current_ip. But before that I want to save their old_ip (from last login) so I thought I could move what is in current_ip to old_ip before copying the new data to current_ip.

I wrote this script when logging in:

........
$sql = mysql_query("SELECT * FROM members WHERE email='$email' AND password='$password'"); 
$login_check = mysql_num_rows($sql);
if($login_check > 0){ 
   while($row = mysql_fetch_array($sql)){ 
    // Get member ID into a session variable
    $id = $row["id"];   
    session_register('id'); 
    $_SESSION['id'] = $id;
    // Get member username into a session variable
    $username = $row["username"];   
    session_register('username'); 
    $_SESSION['username'] = $username;


    // IP getting
    $old_ip = mysql_query("SELECT current_ip FROM members WHERE id='$id'");
    $result_old_ip = $old_ip;
    $sql_setoldip = mysql_query("UPDATE members SET old_ip='".$result_old_ip."' WHERE id='$id'");


    $getip = getenv("REMOTE_ADDR");
    $current_ip = $getip;
    // Update ip in database
    mysql_query("UPDATE members SET current_ip='".$current_ip."' WHERE id='$id'");

}

The result I get in the old_ip feild is “Resource id #7” Any help please ?

Answer 1

mysql_query() statement returns a resource pointer to the result set, not the data itself. You’ll need to use mysql_fetch_array() in order to retrieve the actual data in the table.

like this:

$old_ip = mysql_query("SELECT current_ip FROM members WHERE id='$id'");
$row = mysql_fetch_array($old_ip);
$result_old_ip = $row['current_ip'];

this will solve your problem.

Hope this helps.
