如果在 Woocommerce 中没有应用优惠券,则自动将折扣应用于用户角色

Automatically apply discount to user role if no coupon is applied in Woocommerce

我在下面有这段代码,但我希望它仅在用户未使用其他代码时才有效,并且如果用户使用其他优惠券,则禁用此优惠券。

根据""答案码,一直在想怎么查有没有coupon,一直想不通。

// Applying conditionally a discount for a specific user role
add_action( 'woocommerce_cart_calculate_fees', 'discount_based_on_user_role', 20, 1 );
function discount_based_on_user_role( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return; // Exit

    // Only for 'company' user role
    if ( ! current_user_can('affiliate') )
        return; // Exit

    // Only for 'company' user role
    if ( ! current_user_can('affiliate') )
        return; // Exit

    // HERE define the percentage discount
    $percentage = 15;

    $discount = $cart->get_subtotal() * $percentage / 100;
    // Applying discount
    $cart->add_fee( sprintf( __("Affiliate Discount (%s)", "woocommerce"), $percentage . '%'), -$discount, true );
}

感谢任何帮助。

如果购物车中没有已应用的优惠券,请尝试以下将根据特定用户角色设置自定义折扣的方法:

// Applying conditionally a discount for a specific user role and no applied coupons
add_action( 'woocommerce_cart_calculate_fees', 'discount_based_on_user_role', 20, 1 );
function discount_based_on_user_role( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return; // Exit

    // Only for 'affiliate' user role
    if ( ! current_user_can('affiliate') )
        return; // Exit

    // Only if there is no applied coupons in cart
    if ( ! empty( $cart->get_applied_coupons() ) )
        return; // Exit

    // HERE define the percentage discount
    $percentage = 15;

    $discount = $cart->get_subtotal() * $percentage / 100; // Calculation

    // Applying discount
    $cart->add_fee( sprintf( __("Affiliate Discount (%s)", "woocommerce"), $percentage . '%'), -$discount, true );
}

代码继续在您的活动子主题(或活动主题)的 functions.php 文件中。已测试并有效。
