Change something in db when session unsets


Change something in db when session unsets



I build a basic logout script which unsets all sessions, and changes the 1 under the column "loggedin" to 0 in the database. I need to do that so I can check of a user is loggedin, and post this on the users page. When you close of the browser, all sessions etc. are deleted, but the sql query to update the loggedin column will not be executed. How can I fix this?



if there are any questions, please let me know!



Can you help me?



Code:



Logout script:


require "includes/db.php";

ini_set('session.cookie_domain', '.ictsupport.ga' );
session_start();

$username = $_SESSION['auth'];

//SQL to set loggedin to 1
$sqlStat = "UPDATE account_users SET loggedin = 0 WHERE username='$username';";
/*It changes the 1 in the database to a 0 to let the users page know that the user is offline*/

mysqli_query($con, $sqlStat);

session_unset();
session_destroy();





Add a column "LastSeen" to the user table. Whenever a user loads a page, update their "LastSeen" column. When trying to determine which users are active, ignore those who have "LastSeen" more than X Minutes in the past.

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
