Insert data from session

[Marcos01]

Hello,

 

I want to insert data into an existing row.  It already has the sessionid stored. When I insert now it creates a new row. How do I add data to the existing row?

 

$sessionid = session_id();
$location = $_POST['location'];

$query ="INSERT INTO formusers (sessionid, location) 	
values('{$sessionid}','{$locatie}')";

use the UPDATE function instead of INSERT.
