当购物车中的金额达到阈值时，Woocommerce交易价格带有自定义字段值

Question

当购物车中的数量达到阈值时，我正在尝试更改产品变化的价格。

我的工作来自：WooCommerce: Get custom field from product variations and display it on the “additional information area”和WooCommerce: Bulk Dynamic Pricing Without a Plugin

这是我所拥有的：

   add_action( 'woocommerce_before_calculate_totals', 'bbloomer_quantity_based_pricing', 9999 );

function bbloomer_quantity_based_pricing( $cart, $variation_data ) {

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

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 ) return;
 //get
 $bulk_price = get_post_meta( $variation_data[ 'variation_id' ], 'bulk_price', true);

    if ( $bulk_price ) {

           $threshold1 = 6; // Change price if items > 6
    foreach ( $cart->get_cart() as $cart_item_key => $cart_item ) {
      if ( $cart_item['quantity'] >= $threshold1 ) {
         $price = $bulk_price;
         $cart_item['data']->set_price( $price );

      }

    }   }
}

在您的代码中$variation_data['variation_id']未定义为$variation_data钩子不存在woocommerce_before_calculate_totals…请尝试以下操作：

add_action( 'woocommerce_before_calculate_totals', 'quantity_based_bulk_pricing', 9999, 1 );
function quantity_based_bulk_pricing( $cart ) {

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

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 ) 
        return;

    // Define the quantity threshold
    $qty_threshold = 6;

    // Loop through cart items
    foreach( $cart->get_cart() as $cart_item_key => $cart_item ) {
        // Get the bulk price from product (variation) custom field
        $bulk_price = (float) $cart_item['data']->get_meta('bulk_price');

        // Check if  item quatity has reached the defined threasold
        if( $cart_item['quantity'] >= $threshold && $bulk_price > 0 ) {
            // Set the bulk price
            $cart_item['data']->set_price( $bulk_price );
        }
    }
}

代码进入您的活动子主题（或活动主题）的functions.php文件中。应该可以。
