Session reset?


Recommended Posts

Is there a way to reset a session?


Here is my code...

if (!isset($_SESSION['logged_in'])) 
header("Location: login.php");

mysql_connect("localhost", "user", "password")or die("cannot connect"); 
mysql_select_db("database")or die("cannot select DB");

$bio = $_POST['Bio'];
$location = $_POST['Location'];
$username = $_SESSION["user_name"];

$sql = "UPDATE users SET bio = '$bio', location = '$location' WHERE username = '$username'";
$result = mysql_query($sql) or die ("Error in query: $sql. " . mysql_error());


Now I have a session called bio that I need to reset so that it will store the new bio information. How can I do this? I tried to unset the session and start it again but this didn't work.

it's tough to answer your question, since we have no idea how your session is currently structured or how/where you set the original $_SESSION values. could you not simply use:


$_SESSION['bio'] = $bio;


to rewrite with the new $bio information? you don't necessarily have to "reset" the session, you can simply overwrite the current variables with the new information.
