Question

我正在使用PHP创建一个电子邮件，但我需要在其中添加一个PHP循环和条件语句。这是我的代码：

$message = '
<table width="600" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <td height="50"><strong>Shipping address</strong>
    <p>'.$showDelivery['first_name']." ".$showDelivery['surname'].'</p>
    <p>'.$showDelivery['address1'].'</p>
    <p>'.$showDelivery['address2'].'</p>
    <p>'.$showDelivery['address3'].'</p>
    <p>'.$showDelivery['town'].'</p>
    <p>'.$showDelivery['county'].'</p>
    <p>'.$showDelivery['postcode'].'</p>
    <p>&nbsp;</p>
    <p><strong>Shipping Date</strong> '.$monthName = date("F", mktime(0, 0, 0, $show['shipping_month'], 10)) . " ".$show['shipping_day']." ".$show['shipping_time'].'</p>
    </td>
    <td width="150" height="50">'.if($show['number_of_people'] == 0) {     $show['number_of_people']; }."</td>
</tr>
</table>';

我在上一个表数据中添加了上面的条件，但它没有运行。

有人可以帮忙吗？

非常感谢！

Answer 1

您已将if放入字符串中，这是不对的。

试试这种方式......

$message = '
<table width="600" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <td height="50"><strong>Shipping address</strong>
    <p>'.$showDelivery['first_name']." ".$showDelivery['surname'].'</p>
    <p>'.$showDelivery['address1'].'</p>
    <p>'.$showDelivery['address2'].'</p>
    <p>'.$showDelivery['address3'].'</p>
    <p>'.$showDelivery['town'].'</p>
    <p>'.$showDelivery['county'].'</p>
    <p>'.$showDelivery['postcode'].'</p>
    <p>&nbsp;</p>
    <p><strong>Shipping Date</strong> '.$monthName = date("F", mktime(0, 0, 0, $show['shipping_month'], 10)) . " ".$show['shipping_day']." ".$show['shipping_time'].'</p>
    </td>
    <td width="150" height="50">';

if($show['number_of_people'] == 0) {     
    $message .= $show['number_of_people']; 
}

$message .=.'</td>
</tr>
</table>';

Answer 2

您无法使用字符串连接if()。如果您在提交$message之前，请将变量添加到$message。

例如：

$number = ($show['number_of_people'] == 0) ? $show['number_of_people'] : '';
$message = '.......<td>'.$number.'</td>......';

希望有所帮助：）

Answer 3

假设你要做的是回显变量$ show，那么你需要将echo函数放入你的代码中。

if($show['number_of_people'] == 0) {     $show['number_of_people']; }

应该是

if($show['number_of_people'] == 0) {   echo $show['number_of_people']; }

Answer 4

你可以在开始之前将它声明为变量。

$showPeople = '';
if($show['number_of_people'] === 0){ 
   $showPeople = $show['number_of_people']; 
}

$message = '
<table width="600" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <td height="50"><strong>Shipping address</strong>
    <p>'.$showDelivery['first_name']." ".$showDelivery['surname'].'</p>
    <p>'.$showDelivery['address1'].'</p>
    <p>'.$showDelivery['address2'].'</p>
    <p>'.$showDelivery['address3'].'</p>
    <p>'.$showDelivery['town'].'</p>
    <p>'.$showDelivery['county'].'</p>
    <p>'.$showDelivery['postcode'].'</p>
    <p>&nbsp;</p>
    <p><strong>Shipping Date</strong> '.$monthName = date("F", mktime(0, 0, 0,  
        $show['shipping_month'], 10)) . " ".$show['shipping_day']."
        ".$show['shipping_time'].'</p>
    </td>
    <td width="150" height="50">'. $showPeople ."</td>
</tr>
</table>';
