Woocommerce基于数量的每件商品折扣百分比

问题描述

基于WooCommerce Cart Quantity Base Discount的回答代码，我对购物车中的xx种产品进行了以下折扣：

  add_action( 'woocommerce_cart_calculate_fees','wc_cart_quantity_discount',10,1 );
function wc_cart_quantity_discount( $cart_object ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    ## -------------- DEFINIG VARIABLES ------------- ##
    $discount = 0;
    $cart_item_count = $cart_object->get_cart_contents_count();
    $cart_total_excl_tax = $cart_object->subtotal_ex_tax;

    ## ----------- CONDITIONAL PERCENTAGE ----------- ##
    if( $cart_item_count <= 17 )
        $percent = 0;
    elseif( $cart_item_count >= 18 && $cart_item_count <= 120 )
        $percent = 10;



    ## ------------------ CALculaTION ---------------- ##
    $discount -= ($cart_total_excl_tax / 100) * $percent;

    ## ----  APPLYING CALculaTED disCOUNT TAXABLE ---- ##
    if( $percent > 0 )
        $cart_object->add_fee( __( 'Remise sur la quantité 10%','woocommerce' ),$discount,true);
}

但是我想从每种产品的数量中管理折扣。

您有什么建议吗？

解决方法

以下内容将根据商品数量提供一定百分比的折扣：

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

    $discount = 0; // Initializing
    $percent  = 10;  // Percentage
    
    // Loop through cat items
    foreach ( $cart->get_cart() as $cart_item ) {
        $subtotal = $cart_item['line_total'];
        
        // Calculation by Item based on quantity
        if( $cart_item['quantity'] > 17 ) {
            $discount += $cart_item['line_total'] * $percent / 100;
        }
    }
    
    if( $discount > 0 ) {
        $cart->add_fee( __( "Item quantity discount","woocommerce" ),-$discount,true );
    }   
}

代码在活动子主题（或活动主题）的functions.php文件中。应该可以。
