如果所有已定义类别的产品总数为 1，我想为某些类别添加费用，如果数量为 2-9，我想单独收费。（即，如果他们只订购 1 个，则向产品收取 10 美元，+如果他们订购 2-9 件商品，每件商品 5 美元）。

我从这个基础开始：基于产品尺寸和类别的自定义费用

我有一些改变，但我无法让它工作，我被卡住了。

这是我的代码：

add_action( 'woocommerce_cart_calculate_fees','custom_applied_fee');
function custom_applied_fee() {

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

    // Set HERE your categories (can be an ID, a slug or the name… or an array of this)
    $category1 = 'plain';
    $category2 = 'plywood';

    // variables initialisation
    $fee = 0;

    // Iterating through each cart item
    foreach(WC()->cart->get_cart() as $cart_item){
        // Get the product object
        $product = new WC_Product( $cart_item['product_id'] );
        $quantiy = $value['quantity']; //get quantity from cart

        // Initialising variables (in the loop)
        $cat1 = false; $cat2 = false;

        // ## CALCULATIONS ## (Make here your conditional calculations)
        $quantity = GET TOTAL QUANTITY
        if($quantity <= 1){
            $fee += 10 * $quanity;
        } elseif($quantity > 1 && $dimention <= 9){
            $fee += 5 * $quanity;
        } elseif($dimention > 10){
            $fee += 1 * $quanity;
        }
    }

    // Adding the fee
    if ( $fee != 0 )
        WC()->cart->add_fee( $fee_text, $fee, true );
}

我做错了什么？我怎样才能得到这个工作？

你的需求不是很清楚，所以我已经尽力做到最好。我了解到您要添加：

  • 当定义的产品类别中有 1 个购物车商品时，收取固定的初始费用。
  • 当定义的产品类别中有（2 到 9 个）购物车商品时，根据购物车商品总数计算的费用。

这是相应的代码：

add_action( 'woocommerce_cart_calculate_fees','conditional_custom_multiple_fees', 10, 1 );
function conditional_custom_multiple_fees( $cart_object ) {

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

    // Set HERE your categories (can be an ID, a slug or the name… or an array of this)
    $product_categories = array('clothing', 'disc');
    $cat_qty = 0;
    $cart_total_qty = $cart_object->get_cart_contents_count();

    // Iterating through each cart item
    foreach( $cart_object->get_cart() as $cart_item ){
        $product = $cart_item['data']; // The product object
        $item_qty = $cart_item['quantity']; // Item quantity

        // Counting quanties for the product categories
        if( has_term( $product_categories, 'product_cat', $cart_item['data']->get_id() ) )
            $cat_qty += $cart_item['quantity'];
    }

    ##  --  --  --  --  CALCULATIONS AND CONDITIONAL FEES  --  --  --  --  ##

    // 1. A fee for the product defined categories for 1 cart item only
    if($cat_qty == 1) // updated HERE
    {
        $fee_amount = 10;
        $cart_object->add_fee( __( "Fee (1)" ), $fee_amount, true );
    }

    // 2. Or a calculated fee for the defined product categories (qty from 2 to 9)
    if( $cat_qty >= 2 && $cat_qty <= 9 )
    {
        $amount_by_item = 5; // amount by item (updated)
        $calculated_fee = $amount_by_item * $cat_qty;  // calculation (updated)
        $cart_object->add_fee( __( "Fee (2 to 9)" ), $calculated_fee, true );
    }
}

代码在您的活动子主题（或主题）的 function.php 文件中或任何插件文件中。

此代码经过测试并且可以工作。

感谢LoicTheAztec，我认为只需进行一些小的编辑，您的代码就可以工作......

add_action( 'woocommerce_cart_calculate_fees','conditional_custom_multiple_fees', 10, 1 );
function conditional_custom_multiple_fees( $cart_object ) {

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

// Set HERE your categories (can be an ID, a slug or the name… or an array of this)
$product_categories = array('clothing', 'disc');
$cat_qty = 0;
$cart_total_qty = $cart_object->get_cart_contents_count();

// Iterating through each cart item
foreach( $cart_object->get_cart() as $cart_item ){
    $product = $cart_item['data']; // The product object
    $item_qty = $cart_item['quantity']; // Item quantity

    // Counting quanties for the product categories
    if( has_term( $product_categories, 'product_cat', $cart_item['data']->get_id() ) )
        $cat_qty += $cart_item['quantity'];
}

##  --  --  --  --  CALCULATIONS AND CONDITIONAL FEES  --  --  --  --  ##

// 1. The 1st fee for the product defined categories (qty = 1)
if($cat_qty = 1)
{
    $fee_amount = 10;
    $cart_object->add_fee( __( "Fee (1)" ), $fee_amount, true );
}

// 2. The Separate  additional fee for the defined product categories (qty from 2 to 9)
if( $cat_qty >= 2 && $cat_qty <= 9 )
{
    $amount_by_item = 5; // amount by item
    $calculated_fee = $cat_qty * $amount_by_item;  // calculation
    $cart_object->add_fee( __( "Fee (2 to 9)" ), $calculated_fee, true );
}

}
