woocommerce將車優惠券

Question

我目前正在開發用於woocommerce插件，並有以下的代碼還增加了一個優惠碼如果總的車是在兩個值之間：

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，如果其他語句添加像這裏面又增加了2個值：

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(); 
    } 
} 

出於某種原因，第二if語句只得到檢測，完全無視第一個。有什麼明顯錯誤與上面？

Answer 1

也許，如果你改變了兩個單獨的語句爲IF，ELSEIF，否則 - 它會工作。

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(); 
    } 


}
