    global $woocommerce;
$amount =  $woocommerce->cart->get_cart_item_quantities();
if($amount==5)
{
    $excost = 7;
    }
    else if($amount==7){
    $excost = 8;
    }
    $woocommerce->cart->add_fee('Charges delivery', $excost, $taxable = false, $tax_class = '');
}

推荐答案

请试试这个

function woocommerce_custom_surcharge(){ 
global $woocommerce;
//Getting Cart Contents. 
$cart = $woocommerce->cart->get_cart();
//Calculating Quantity
foreach($cart as $cart_val => $cid){
        $qty += $cid['quantity']; 
    }
//Your Condition
if($qty==5)
{
    $excost = 7;
    }
    else if($qty==7){
    $excost = 8;
    }

    $woocommerce->cart->add_fee('Charges delivery', $excost, $taxable = false, $tax_class = '');


}

从这里我发现我们需要通过总结购物车的价值来获得购物车的数量.希望这能解决您的问题.

From Here I found that We need to get the quantity of the cart by summing up the values of the cart.Hope this will Solve your problem.
