woocommerce应用购物车优惠券

Question

我目前正在为woocommerce开发一个插件，如果购物车的总数介于两个值之间，请使用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();
    }
}

以上工作正常，但是我想添加另一个if语句，它增加了另外两个值：

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，只检测到第二个if语句，完全忽略第一个。上面有什么明显的错误吗？

Answer 1

也许如果你将两个单独的语句改为if，elseif，else - 它就可以了。

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();
    }


}
