Sessions error speedy question

[djumaka]

Hi!
😕
I recently used some sessions for a cart for an e-shop. So I stored the data into arays (one for item id, quantity and prise). So I the tried to access these "session" arrays directly on the page to show the shopping cart.

BUTT!

When I check if it exists (by session_is_registered, 'cause isset did not catch the arrays) it showed me no problems. But when I tried to access any of the arrays it said "Undefined variable". So what can I do. Is there a session function to call these variables instedad the direct way.

TIA.

P.S.: If you got any example code please send it to me.

i dont know what problem about it

but i suggest you use session like this,
assuming there are 2 page named a.php and b.php

a.php

session_start();
$cart = array();

$_SESSION['cart'] = $cart; //register the $cart array as a variable

b.php
if (isset($SESSION['cart']) //check if the variable is register
//the same as session_is_registered()
$cart = $SESSION['cart']; //get the array back

$_SESSION = array() //the same as session_unregister()

//then destroy the session
session_destroy();
