Php购物车问题

我试图修复wordpress的awm商店插件中的一个php问题，这可能很简单，但我的php技能不是最好的，我试图解决的问题没有成功

我已设置购物车，以便：

澳大利亚居民始终免费送货 对于非居民，运费为15美元，但如果他们订购超过500美元，则免费

使用以下代码：

foreach( $cart_items as $items ) {
        if( $items['type'] == "purchase" ) {
            $amount = $amount + ( $items['price'] * $items['quantity'] );
        }else{
            $amount = $amount + ( $items['price'] * $items['quantity'] );
        }
    }

    $country = "";

    if( $order_details['billing_not_shipping'] ){
        $country = $order_details['shipping_country'];
    }else{
        $country = $order_details['billing_country'];
    }

    if( strtolower($country) == "australia" )
    {
        $this_quote = $simple_shipping_options[1]['order_fee'];
        foreach($cart_items as $cart_item){
            $this_quote += $cart_item['quantity'] * $simple_shipping_option['product_fee'];
        }
        $return_quotes[] = array(
            'name' => $simple_shipping_options[1]['name'],
            'total' => $this_quote,
        );
    }
    else
    {
        if( $amount > 500 ) {
            $this_quote = $simple_shipping_options[0]['order_fee'];
            foreach($cart_items as $cart_item){
                $this_quote += $cart_item['quantity'] * $simple_shipping_option['product_fee'];
            }
            $return_quotes[] = array(
                'name' => "Free Shipping for any order over $500",
                'total' => $this_quote,
            );
        }else{
            $this_quote = $simple_shipping_options[1]['order_fee'];
            foreach($cart_items as $cart_item){
                $this_quote += $cart_item['quantity'] * $simple_shipping_option['product_fee'];
            }
            $return_quotes[] = array(
                'name' => $simple_shipping_options[1]['name'],
                'total' => $this_quote,
            );
        }
    }

    return $return_quotes;
}

及

澳大利亚境内免费送货
嗯，我想你只需要把澳大利亚国际单项体育联合会的声明拿出来

改变

if（strtolower（$country）=“澳大利亚”）

到

if（strtolower（$country）=“australiaX”）

忽略这句话。。或

/*    if( strtolower($country) == "australia" )
    {
        $this_quote = $simple_shipping_options[1]['order_fee'];
        foreach($cart_items as $cart_item){
            $this_quote += $cart_item['quantity'] * $simple_shipping_option['product_fee'];
        }
        $return_quotes[] = array(
            'name' => $simple_shipping_options[1]['name'],
            'total' => $this_quote,
        );
    }
    else
    {
*/ 
       if( $amount > 500 ) {
            $this_quote = $simple_shipping_options[0]['order_fee'];
            foreach($cart_items as $cart_item){
                $this_quote += $cart_item['quantity'] * $simple_shipping_option['product_fee'];
            }
            $return_quotes[] = array(
                'name' => "Free Shipping for any order over $500",
                'total' => $this_quote,
            );
        }else{
            $this_quote = $simple_shipping_options[1]['order_fee'];
            foreach($cart_items as $cart_item){
                $this_quote += $cart_item['quantity'] * $simple_shipping_option['product_fee'];
            }
            $return_quotes[] = array(
                'name' => $simple_shipping_options[1]['name'],
                'total' => $this_quote,
            );
        }
/*    }*/

    return $return_quotes;

你的逻辑看起来是正确的。你遇到的问题是什么？它适用于除澳大利亚以外的所有国家。对于澳大利亚来说，它总是免费的，即0美元，我需要适用于其他所有国家的相同规则来适用于asutralian。所以如果是500美元，就要收0美元。如果不清楚，请告诉我！好吧，那么你可能会把总运费乘以-是吗？我不这么认为。运费是最后加上的一个金额，设定为15美元。我已经在上面添加了一些代码，如果这让它更清晰的话。我试过了，但它似乎仍然在应用免费送货到澳大利亚。我将添加表单表，允许我在wordpress中更改发货量，但我也尝试过编辑它，我没有任何乐趣。谢谢你的帮助！
print\r（$simple\u shipping\u options）的输出是什么if（strtolower（$country）=“australia”）
更改为
if（strtolower（$country）=“australiaX”）
，这样它就忽略了这个语句。。看看它是否因为某种原因应用了你想要的规则，它仍在应用该规则。我现在很困惑，因为我尝试了不同的方法，试图让它忽略这个声明，但做不到。我被难住了！谢谢你的努力
