WooCommerce - 如果数量超过1，则将购物车项目分开处理

我正在尝试执行以下操作：

客户将数量为“1”的产品添加到购物车（数量字段已在单个产品页面上删除，因此只能添加1个） .

如果再次添加具有相同变体的相同产品，而不是将数量增加到“2”，则将其添加为单独的产品 .

我设法使用下面的过滤器执行上述操作，我在WordPress论坛上找到了它 .

add_filter('woocommerce_add_cart_item_data', 'force_separate_item_add', 10, 2);
function force_separate_item_add($cart_item_data, $product_id) {

    $unique_cart_item_key = md5(microtime().rand()."Hi Mom!");
    $cart_item_data['unique_key'] = $unique_cart_item_key;

    return $cart_item_data;
}

这家伙的解释非常好，我明白了："When an item gets added to the cart, a 'key' for that individual item in the cart is created based on the item being added and its associated meta data. If the item and its meta data are identical to another item in the cart, then the generated key will be identical too, and the the quantity of the item already in the cart will simply be incremented by the quantity being added" .

上面的代码只是添加了一个新密钥，然后购物车将它们视为单独的条目 .

What I'm trying to do now is to find the appropriate filter for this when the quantity gets changed through the cart. So if the customer changes the quantity to "2" it will generate a new key for the "2nd" item and treat it individually.

我已经尝试了几乎所有可以找到的“购物车”相关过滤器，在WooCommerce文档上搜索，在“更新购物车”，“购物车”等的woocommerce插件文件夹上进行Sublime上的大量搜索，但我担心我我真的不确定要使用哪个 . 我最努力的是这一个：

add_action('woocommerce_before_calculate_totals', 'change_cart_item_price');
function change_cart_item_price($cart_object) {

    global $woocommerce;

    foreach ($woocommerce->cart->cart_contents as $cart_key => $cart_item_array) {        
        if($cart_item_array['quantity'] > 1 ) {
            $cart_item_key = md5(microtime().rand()."Hi Mom!");
            $cart_item_data['unique_key'] = $cart_item_key;

            $woocommerce->cart->set_quantity($cart_item_key, '1');
        }
   }

   return $cart_object;
}

在这里，我正在浏览购物车对象，检查数量是否大于1，如果是，我分配一个新密钥 . 我真的不知道我是做正确的事情，还是我完全偏离轨道所以任何指针都会非常感激 .

如果您需要更多信息，请告诉我，我会尽力提供一切 .

非常感谢 .

    你的 woocommerce_add_cart_item_data 过滤器对我来说是一个很好的开始 . 我最终离开了原样并转移到 woocommerce_add_to_cart 钩子来手动处理 .

    这是目前为我工作的一个苗条版本 .

    /**
 * This hook runs at the end of the default add to cart processes, when you try to add an item to cart.
 * If trying to add more than item to the cart, separate them into individual cart items
 *
 * @author  Mike Hemberger <mike@bizbudding.com>
 *
 * @return  void
 */
add_action( 'woocommerce_add_to_cart', 'mai_split_multiple_quantity_products_to_separate_cart_items', 10, 6 );
function mai_split_multiple_quantity_products_to_separate_cart_items( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ) {

    // If product has more than 1 quantity
    if ( $quantity > 1 ) {

        // Keep the product but set its quantity to 1
        WC()->cart->set_quantity( $cart_item_key, 1 );

        // Run a loop 1 less than the total quantity
        for ( $i = 1; $i <= $quantity -1; $i++ ) {
            /**
             * Set a unique key.
             * This is what actually forces the product into its own cart line item
             */
            $cart_item_data['unique_key'] = md5( microtime() . rand() . "Hi Mom!" );

            // Add the product as a new line item with the same variations that were passed
            WC()->cart->add_to_cart( $product_id, 1, $variation_id, $variation, $cart_item_data );
        }

    }

}
