Question

我正在尝试向以下代码添加if语句，只需要澄清一下它是否能做正确的工作。

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 />

尝试添加运费＆amp;处理：在那里结果是：

<?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？

Answer 1

是的，如果选择paymentmethod选项作为paypal，它将回显“Shipping＆amp; Handling = $ GRANDTOTAL * .045”，如果检查，它将回显“Shipping＆amp; Handling = 0”

Answer 2

像这样：

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

if ($paymethod == $paypal)
    echo "Shipping & Handling =". $GRANDTOTAL * .045;

elseif ($paymethod == $check)
    echo "Shipping & Handling = 0";

else
echo "Invalid parameter.";
?>

如果您不想计算运费和;处理如上所述：

echo "Shipping & Handling = $GRANDTOTAL * .045";

Answer 3

确保$paymethod不是$PAYMETHOD，它区分大小写。并确保$paymethod必须等于paypal或check，它也区分大小写。
