Question

在有人注册我的网站后，他们必须获得加入它的权限。我已经设置了一个组数据库表，如果有人是组1级，他们就无法访问该站点。然后，如果某人是2-5组，他们就可以。每当我更改该组级别时，我都希望向他们发送电子邮件。电子邮件工作正常，但我无法弄清楚如何做到这一点：

我希望将任何组级别发送到我的php文件2-6，给出不同的消息并回显我指定的变量。因此，如果有人被授予第2组，我想要这部分电子邮件......

<p>You have been put into the permission category of </p><br>

说

<p>You have been put into the permission category of Spectator. This level of permission allows you to do basic site tasks</p><br>

我只是不确定如何构建它，因此它根据授予的用户和组级别而有所不同。

我该如何做到这一点？

if($change_group = 2) {
    $group2 = "Spectator";
    $group2Message = "This level of permission allows you to do basic site taks....."
}
if($change_group = 3) {
    $group3 = "Team Member";
    $group3Message = "This level of permission allows ....."
}
if($change_group = 4) {
    $group4 = "Commissioner";
    $group4Message = "This level of permission allows ....."
}
if($change_group = 6) {
    $group6 = "Denied";
    $group6Message = "This level of permission allows ....."
}
        $to = $email;
        $subject = 'Permission Status';
        $message = '
        <html>
        <head>
            <title>Group Change</title>
        </head>
        <body>
            <p>Hi '.$firstname.',</p><br>
            <p>You have been added to the group.. </p><br>

Answer 1

让if($change_group = 2)返回true，因为它成功地将变量$change_group分配给值2.使用==代替，检查值是否等于2.

这是使用switch代替一系列if语句的好地方，但这样做并没有错。

 if ($change_group == 2) {
     $groupname = "Spectator";
     $groupmessage = "do basic site tasks";
 } elseif ($change_group == 3) {
     $groupname = "Team Member";
     $groupmessage = "do other tasks";
 } elseif ($change_group == 4) {
     $groupname = "Commissioner";
     $groupmessage = "act like a boss";
 } elseif ($change_group == 6) {
     $groupname = "Denied";
     $groupmessage = "be denied";
 }

然后你的$message设置为类似

 $message = '
 <html>
 <head>
     <title>Group Change</title>
 </head>
 <body>
    <p>Hi '.$firstname.',</p><br>
    <p>You have been put into the permission category of '.$groupname.'! This level of permissions allows you to '.$groupmessage.'.</p><br>';

然后你只需按照你想要的方式格式化它！

不是使用一堆elseif，甚至是一个开关，另一种可能性是创建一个组数组，并根据$change_group值从数组中提取。

<?php
$groups = array(
    2 => array('name' => 'Spectator', 'message' => 'This level of permission allows you...'),
    3 => array('name' => 'Team Member', 'message' => 'This level of permission allows ...'),
    4 => array('name' => 'Commissioner', 'message' => 'This level of permission allows ...'),
    6 => array('name' => 'Denied', 'message' => 'This level of permission allows ...')
);

'<p>You have been added to the group '.$groups[$change_group]['name']
    .' '.$groups[$change_group]['message'].'</p><br>';

最终，您可能希望将这些值存储在数据库中，而不是对其进行硬编码。
