php - woocommerce 应用购物车优惠券

Question

我目前正在为 woocommerce 开发一个插件，并且如果购物车的总数介于 2 个值之间，则具有以下代码添加折扣代码：

add_action('woocommerce_before_cart', 'woobd_add_discount_if_enabled');

function woobd_add_discount_if_enabled()
{
    global $woocommerce;
    if ($woocommerce->cart->cart_contents_total >= 10
        && $woocommerce->cart->cart_contents_total <= 100
    ) {
        $woocommerce->cart->add_discount('layer1_discount');
    } else {        
        $woocommerce->cart->remove_coupons('layer1_discount');
        $woocommerce->cart->calculate_totals();
    }
}

上面的工作正常，但是我想添加另一个像这样的 if 语句，它增加了另外 2 个值：

add_action('woocommerce_before_cart', 'woobd_add_discount_if_enabled');

function woobd_add_discount_if_enabled()
{
    global $woocommerce;
    if ($woocommerce->cart->cart_contents_total >= 10
        && $woocommerce->cart->cart_contents_total <= 100
    ) {
        $woocommerce->cart->add_discount('layer1_discount');
    } else {        
        $woocommerce->cart->remove_coupons('layer1_discount');
        $woocommerce->cart->calculate_totals();
    }

    if ($woocommerce->cart->cart_contents_total >= 100
        && $woocommerce->cart->cart_contents_total <= 200
    ) {
        $woocommerce->cart->add_discount('layer2_discount');
    } else {        
        $woocommerce->cart->remove_coupons('layer2_discount');
        $woocommerce->cart->calculate_totals();
    }
}

由于某种原因，仅检测到第二个 if 语句，而完全忽略了第一个。以上有什么明显的错误吗？

Answer 1

也许如果您将两个单独的语句更改为 if、elseif、else - 它会起作用。

add_action('woocommerce_before_cart', 'woobd_add_discount_if_enabled');

function woobd_add_discount_if_enabled()
{
    global $woocommerce;
    if ($woocommerce->cart->cart_contents_total >= 10
        && $woocommerce->cart->cart_contents_total <= 100
    ) {
        $woocommerce->cart->add_discount('layer1_discount');
    } elseif ($woocommerce->cart->cart_contents_total >= 100
        && $woocommerce->cart->cart_contents_total <= 200
    ) {        
        $woocommerce->cart->add_discount('layer2_discount');
    } else {        
        $woocommerce->cart->remove_coupons('layer1_discount');
        $woocommerce->cart->remove_coupons('layer2_discount');
        $woocommerce->cart->calculate_totals();
    }


}
