在购物车上添加费用以及属性和数量

Posted 2021-04-12

我想向Woocommerce添加额外的费用。如果在购物车中我们只有很少的商品具有属性“ consigne”，则仅返回一个product_ID的费用。如何解决问题？ （对不起，我的英语不完善：-D）

function woo_add_cart_fee(){
global $woocommerce;

if(is_admin() && !defined('DOING_AJAX'))
    return;

//Initialisation of costs
$consigne = 0.5;

//cart
$cart = $woocommerce->cart->get_cart();
foreach($cart as $product)
{
    $the_product = get_product($product['product_id']);

    //fee - products
    $nb_products = $product['quantity'];
    $activation_cost += ((float) $the_product->get_attribute('Consigne')) * $nb_products;
}

//intergration fees

if( $activation_cost >= 0 )
{
    $woocommerce->cart->add_fee("Consigne", $consigne*$nb_products, true, '');
}

}
add_action('woocommerce_cart_calculate_fees', 'woo_add_cart_fee');

答案

我找到了解决方案：

'函数woo_add_cart_fee（）{全球$ woocommerce;

if(is_admin() && !defined('DOING_AJAX'))
    return;

//Initialisation des coûts
$consigne = 0.5;

//Parcours du panier
$cart = $woocommerce->cart->get_cart();
foreach($cart as $product)
{
    $the_product = get_product($product['product_id']);

    //Frais d'activation, un coût par produit
    $nb_products1 = $product['quantity'];
    $activation_cost += ((float) $the_product->get_attribute('Consigne')) * $nb_products1;
    if(  $activation_cost >= 0  )
    {
        $nb_products = $nb_products + $nb_products1 ;
    }
}

//Application des coûts calculés

if( $nb_products >= 0 )
{
    $woocommerce->cart->add_fee("Consigne", $consigne*$nb_products, true, '');
}

}add_action（'woocommerce_cart_calculate_fees'，'woo_add_cart_fee'）; '
