试图创建一个2步代码“if语句” [英] trying to create a 2 step code "if statement"

问题描述

我正在尝试向以下代码添加if语句，只需要澄清它是否能做正确的工作。

i am trying to add a if statement to the following code, just need clarification to see if it will do the right job.

Order #: <? echo $ORDERID?><br />
<br />
Pick-Up Date: <? echo $MYPICKUP?><br />
Comments: <? echo $COMMENTS?><br /><br />        
<? echo $CART?><br />
Order total: $<? echo $GRANDTOTAL?><br />
Payment Method: <? echo $PAYMETHOD?></span><span class="TextB"><br />

尝试添加Shipping&处理：在那里结果是：

trying to add Shipping & Handling: in there with the result being :

<?php
$paypal = 'paypal';
$check = 'check';

if ($paymethod == $paypal)
{
    echo "Shipping & Handling = $GRANDTOTAL * .045";
}
    elseif ($paymethod == $check)
{
    echo "Shipping & Handling = 0";
}
?>

但我的问题是，选择该选项后是否会显示运费和处理金额？

but my question is, will the shipping and handling amount show up when the option is chosen?

推荐答案

确保 $ paymethod 不是 $ PAYMETHOD ，区分大小写。
并确保 $ paymethod 必须等于 paypal 或检查，它也区分大小写。

make sure $paymethod is not $PAYMETHOD, it is case sensitive. and make sure the $paymethod must equals paypal or check, it is also case sensitive.
