如何使用購物車總數更改 WooCommerce 中的購物車商品價格

[英]How to use cart total to change cart items prices in WooCommerce

I am trying to pass the total amount of the cart ( $GetTotalPrice ) from function cart_prices_GetPrice() to function cart_prices_ApplyPrice() , using a woocommerce_after_calculate_totals and woocommerce_before_calculate_totals hooks, but I get an empty value.

//Trying to get cart amount
add_action('woocommerce_after_calculate_totals', 'cart_prices_GetPrice'); 
function cart_prices_GetPrice()  {

    //Getting the cart amount
    $GetTotalPrice = WC()->cart->get_cart_total();
    return $GetTotalPrice;

}

//Applying custom price
add_action('woocommerce_before_calculate_totals', 'cart_prices_ApplyPrice');
function cart_prices_ApplyPrice( $cart_object ) {

    //Getting the cart amount from first function
    
    $totalprice = cart_prices_GetPrice(); // doesn't work and returns 0 :(


    //price change to cost2
    if( $totalprice != 0 && $totalprice >= 2000 ) {
       foreach ( $cart_object->get_cart() as $cart_id => $cart_item ) {
            
               // get products id
               $product_id = $cart_item['product_id'];
               if( $cart_item['product_id'] == $product_id ) {
                   
               // price change to cost2
               $new_price1 = 0.20;
               $cart_item['data']->set_price( $new_price1 );
               
              }

       } 
    } 
 }

同時,每個功能都可以完美運行。
我究竟做錯了什么? 是否有可能以某種方式鏈接兩個鈎子數據,以便第一個不返回空值?


更新:
我將無法拒絕鈎子woocommerce_before_calculate_totals ,因為我需要為購物車中的每個產品單獨降價。

當您出於多種原因想要更改購物車商品價格時,您根本不能在woocommerce_before_calculate_totals中使用購物車總數……

相反,您將在woocommerce_before_calculate_totals掛鈎中獲得購物車項目小計。 在下面的代碼中,我使用了包含稅費的折扣購物車商品小計:

add_action('woocommerce_before_calculate_totals', 'customize_cart_item_prices');
function customize_cart_item_prices( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // Avoiding the hook repetition for price calculations
    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    $threshold_amount = 1000; // Min subtotal
    $discount_rate    = 0.2; // price discount rate (20%)

    $cart_items       = $cart->get_cart();

    // Getting non discounted cart items subtotal
    $subtotal_excl_tax = array_sum( wp_list_pluck( $cart_items, 'line_subtotal' ) );
    $subtotal_tax = array_sum( wp_list_pluck( $cart_items, 'line_subtotal_tax' ) );

    // Getting discounted cart items subtotal
    $total_excl_tax = array_sum( wp_list_pluck( $cart_items, 'line_total' ) );
    $total_tax = array_sum( wp_list_pluck( $cart_items, 'line_tax' ) );

    if( ( $total_excl_tax + $total_tax ) >= $threshold_amount ) {
        // Loop through cart items
        foreach ( $cart_items as $item ) {
            $price = $item['data']->get_price(); // Get price

            $item['data']->set_price( $price * ( 1 - $discount_rate ) ); // Set new price
        }
    }
}

代碼進入活動子主題(或活動主題)的functions.php文件。 測試和工作。
