Hi, I'm quite stuck since this afternnon. I tried many ways to get a result (using {count} and many other things I saw on documenttaion and internet) but none of them worked. Here is my infos :

$session

Code:
Value
Array (4)
msg => "You must log in first"
email => "jeff@gmail.com"
success => "You are now logged in"
shopping_cart => Array (2)
  0 => Array (7)
    id => "179"
    title => "ruyrytur"
    image => "Luxury-Sofa-for-Main-Room-at-Home-Design-Luxury-with-Stunning-Outdoor.jpg"
    variants => Array (0)
    quantity => 3
    unit_price => "123.00"
    price => 123
  1 => Array (7)
    id => "2"
    title => "Vewlix 1080p (red and white)"
    image => "amazing-modern-villa-Freshome-02.jpg"
    variants => Array (1)
      0 => Array (3)
        option_id => "1"
        option_name => "Panel 1 player"
        option_price => "0.00"
    quantity => 1
    unit_price => "1950.00"
    price => 1950


I'm trying with a foreach to get the sum of the value 'quantity' (that should be 4).

Code:
{foreach $session.shopping_cart as $cart}
   {$cart.quantity|@count}
{/foreach}


with no luck.

I also tried

Code:
{foreach $session.shopping_cart as $cart}
   {$cart.quantity}
{/foreach}


that works with one product, but if I add another one it doesn't count, simple displays me 3 and 1.

Any help?

I would try:
Code:
{$cart_item_count = 0}
{foreach $session.shopping_cart as $cartItem}
{$cart_item_count += $cartItem.quantity}
{/foreach}
Total item count: {$cart_item_count}

Code:
{$cart_item_count += $cartItem.quantity}" - Unexpected "= "
Interesting. It then appears that Smarty (at least the version you are using) does not know about the operator shortcuts.

So, try:
Code:
{$cart_item_count = $cart_item_count + $cartItem.quantity}
