关于购物车中的数组项目的Woocommerce问题

Question

This is my code in cart:

<?php 
$totaleiva_1 = 0;
$items = $woocommerce->cart->get_cart();
foreach($items as $item ) {
    echo $totaleforsebene;
    $totaleiva_1 = $totaleiva_1 + $totaleforsebene;
}
echo $totaleiva_1;
?>

The result is: the $totaleforsebene value of the last product in cart is added n times for product I have (for example I have two products, the last value $totaleforsebene is added two times).

Instead, I would want to have the $totaleforsebene for different products and then They are been added.

Thanks for help

You can create array with ID for each product and then add the correct value:

When you calculate the $totaleforsebene do this:

foreach($items as $item => $values) {
    $product = wc_get_product( $values['data']->get_id());
    ...
    $totaleforsebene = ($scontato * $percent)/100; 
    $totalForSebeneArray[$values['data']->get_id()] = $totaleforsebene; // add the value by the item ID
    $totaleforsebene = number_format($totaleforsebene, 2, '.', '')." €"; 
}

Now, when you loop on the item and sum you can do:

$totaleiva_1 = 0;
$items = $woocommerce->cart->get_cart();
foreach($items as $item ) {
    $totaleiva_1 += $totalForSebeneArray[$item ['data']->get_id()];
}
echo $totaleiva_1;

You also need to format your question better as now it is very hard to understand your issue and I am not even sure if my explanation answer your problem...
