Solution:

How has no one seen this:

{-code-1}
Copy code

Make it{-code-2}

You also need another 2} to close yourif() andfor() statements so it's like this:

function removeitem ($item){
    $arrayCart = $_SESSION['cart'] ;
    for ($i=0; $i<$arrayCart.length; $++ ){
        if ($item.id == $arrayCart[i].id){
            $arrayCart.splice (i,0); 
        }
    }
}

Have you tried using this?

if(!isset($_SESSION['cart'])){
  $_SESSION['cart'] = [];
}
$_SESSION['cart'][] = $item;
Copy code

You don't need to serialize the item-variable - a Session can store pure Objects, as long as the max. session-size doesn't exceed.

If you want to remove Items from the cart, you should use index-Names - this allows you to find your items faster.

I would probably use something like this:

if(!isset($_SESSION['cart'])){
  $_SESSION['cart'] = [];
}

function addItem($itemName){
    if(!isset($_SESSION['cart'][$itemName])) {
        $_SESSION['cart'][$itemName] = 1;
    }else
        $_SESSION['cart'][$itemName] ++;
    }
}
function removeItem($itemName){
    if(isset($_SESSION['cart'][$itemName])) {
        if($_SESSION['cart'][$itemName] > 0) {
            $_SESSION['cart'][$itemName] --;
        }
    }
}

function clearCart(){
   unset($_SESSION['cart']);
}
Copy code

In this case, the cart stores each item and its amount. Instead of$itemName, you could also use the item-ID from your database.

To get an item from the cart, you will need this function:

function getItemCount($itemName){
    if(isset($_SESSION['cart'][$itemName])) {
        return $_SESSION['cart'][$itemName];
    }
    return 0;
}

Solution:

Try not pushing to array, because its probably not set yet, but to store to session, create new session var by:

$_SESSION['cart']=serialize($item);
Copy code

to remove it:

unset($_SESSION['cart']);
Copy code

EDIT:

Thanks to comments I realized that above code wouldn't store array in session. So, another short solution is to store to session var some JSON. Try this for a short test:

$tmp = array(1,2,3);
$_SESSION['cart']=json_encode($tmp);
print_r(json_decode($_SESSION['cart']));
Copy code

If that array is associative, you shoud use for decode:

json_decode($_SESSION['cart'], true);
Copy code
