Can't store multidimensional data with Session Library

[desttools]

I was trying to store a multidimensional array using Session Library, and it is failing when I try to call set(). Not sure if this is a bug or just an unimplemented feature.

My shopping cart array $cart is set up like this:

Array ( [0] => Array ( [item] => Adult [qty] => 2 [price] => 38.02 ) [1] => Array ( [item] => Child (Ages 4-12) [qty] => 2 [price] => 17.68 ) [2] => Array ( [item] => Lap Child (Ages 0-3) [qty] => 2 [price] => 0 ) [3] => Array ( [item] => Family Pass (Max 3 kids) [qty] => 1 [price] => 87.53 ) [total] => 198.93 )

And I'm trying to store it like this:

$session->set($cart);

It fails and I get this error from the debugger:

**ErrorException
Illegal offset type

SYSTEMPATH/Session\Session.php at line 469**

if (is_int($key)) { $_SESSION[$value] = null; }

I was able to work around this by doing json_encode() on the data and storing it as a name-value pair. I was also able to store it with pure PHP like $_SESSION['cart'] = $cart;

CodeIgniter 4 version
CodeIgniter 4.0.0-r2.1

$session->set($data) expects $data to be an array of key/value pairs. The key is used as the associative index to $_SESSION I believe what you want to do is something like this

$_SESSION['cart'] = $cart;

@dafriend is correct here. That's not a bug, you're just not providing anything to index it by, which means there's no way to retrieve it.

That makes sense. Thanks guys!
