Question

How can I filter out online users, if I have a column “lastaccess” that have a unix time() stamp. Then I usually have this function:

function showStatus($userid) {
    $timeoutIdle = 80;
    $timeoutOffline = 150;
    $row = mysql_query("select last_access from users where id='$userid'");
    $read = mysql_fetch_array($row);
    $last_access = $read["last_access"];
    $thetime = time();
    if ($thetime - $last_access > $timeoutOffline) {
        echo "";
    }
    else if ($thetime - $last_access > $timeoutIdle) {
        echo "<span class='statusIdle'>Idle</span>";
    } else {
        echo "<span class='statusOnline'>Online</span>";
    }
}

How do I make a query, where it displays if you’re online?

Answer 1

$sql = "SELECT
          CASE
            WHEN last_access < UNIX_TIMESTAMP()-150 THEN 'offline'
            WHEN last_access < UNIX_TIMESTAMP()-80 THEN 'idle'
            ELSE 'online'
          END AS online_status
        FROM users
        WHERE id = $userid";
