如果低于最低金额的小计，不会申请优惠券。

Question

我有问题。我有优惠券给我15%的折扣。此外，我有至少200美元的运输方法。我注意到，如果我申请的优惠券金额为200美元，小计低于200美元，优惠券运输方法有效。我想知道一个办法，以限制智能优惠券不适用，如果小计低于200美元。

我正在尝试的代码是：

add_action( 'woocommerce_before_cart' , 'home_test_coupon_fix' );
add_action( 'woocommerce_before_checkout_form' , 'home_test_coupon_fix' );
function home_test_coupon_fix() {
    $cart_total = WC()->cart->get_subtotal();
    $coupon_id = 'hometest';
    $minimum_amount = 200 + WC()->cart->get_coupon_discount_amount( 'hometest' );
    $currency_code = get_woocommerce_currency();
    wc_clear_notices();
    
    echo $minimum_amount;

    if ( $cart_total < $minimum_amount && $woocommerce->cart->applied_coupons === $coupon_id ) {
         WC()->cart->remove_coupon( 'hometest' );
         wc_print_notice( "Get 50% off if you spend more than $minimum_amount $currency_code!", 'notice' );
    } 
    wc_clear_notices();
}

Answer 1

您的代码中有一些bug。首先，您没有将global $woocommerce;声明为函数的启动。$woocommerce->cart->applied_coupons，这将是数组，所以您必须传递键来检查hometest

add_action( 'woocommerce_before_cart' , 'home_test_coupon_fix' );
add_action( 'woocommerce_before_checkout_form' , 'home_test_coupon_fix' );

function home_test_coupon_fix() {
    global $woocommerce;
    $cart_total     = WC()->cart->get_subtotal();
    $coupon_id      = 'hometest';
    $minimum_amount = 500 + WC()->cart->get_coupon_discount_amount( $coupon_id );
    $currency_code  = get_woocommerce_currency();
    wc_clear_notices();
    if ( $cart_total < $minimum_amount && $woocommerce->cart->applied_coupons[0] === $coupon_id ) {
        WC()->cart->remove_coupon( 'hometest' );
        wc_print_notice( "Get 50% off if you spend more than $minimum_amount $currency_code!", 'notice' );
    } 
    wc_clear_notices();
}

按OP请求更新

您可以使用woocommerce_coupon_message过滤器钩子删除优惠券消息。

function remove_coupon_message( $msg, $msg_code, $this ){
    global $woocommerce;
    $cart_total     = WC()->cart->get_subtotal();
    $coupon_id      = 'hometest';
    $minimum_amount = 500 + WC()->cart->get_coupon_discount_amount( $coupon_id );
    $currency_code  = get_woocommerce_currency();
    wc_clear_notices();
    if ( $cart_total <= $minimum_amount && $woocommerce->cart->applied_coupons[0] === $coupon_id ) {
        return "";  
    }
    return $msg;
}
add_filter('woocommerce_coupon_message','remove_coupon_message', 10,3 );

测试和工作.
