我正在使用PHP OOP开发CMS。在这个CMS中，有一个功能，网站管理员可以添加另一个管理员。我为此做的是，我创建了一个表单并添加了操作。此文件名为admin_new.php，如下所示：
<?php
if (isset($_POST['submit'])){
$username = $_POST['uname'];
$email = $_POST['email'];
$password = $_POST['pass'];
$groups = $_POST['groups'];
if($groups == "Main Admin"){
$level = 1;
}else if($groups == "Administrator"){
$level = 2;
}else if($groups == "Content Creator"){
$level = 3;
}else if($groups == "Social Media Manager"){
$level = 4;
}else{
$level = 5;
}
if (filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
$notice['email_validation'] = "The email that you have entered is not a valid one";
}else{
$registration = new Register();
$notice = $registration->CheckUname($username,$email,$password,$groups,$level);
}
}
?>
<div class="content-wrapper">
<section class="content-header">
<h1>
Add New Admin
<small>You can add new admin here</small>
</h1>
<ol class="breadcrumb">
<li class="active">addnewadmin.php</li>
</ol>
</section>
<section class="content">
<div class="row">
<div class="col-md-6">
<div class="box box-primary">
<div class="box-header with-border">
<h3 class="box-title">Required Information</h3>
</div>
<?php
if(isset($notice['email_validation'])) {
echo "
<div class='alert alert-danger'>
<strong>Hey!</strong> ".$notice['email_validation'].".
</div>
";
}
if(isset($notice['username_exists'])) {
echo "
<div class='alert alert-danger'>
<strong>Hey!</strong> ".$notice['username_exists'].".
</div>
";
}
if(isset($notice['email_exists'])) {
echo "
<div class='alert alert-danger'>
<strong>Hey!</strong> ".$notice['email_exists'].".
</div>
";
}
if(isset($notice['success_message'])) {
echo "
<div class='alert alert-success'>
<strong>Hey!</strong> ".$notice['success_message'].".
</div>
";
}
?>
<form role="form" method="POST" action="">
<div class="box-body">
<div class="form-group">
<label>User name</label>
<input type="text" class="form-control" placeholder="Enter username" name="uname" required>
</div>
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email" name="email" required>
</div>
<div class="form-group">
<label for="exampleInputPassword1">Temporary password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Enter password" name="pass" required>
</div>
<div class="form-group">
<label>Group admin</label>
<select class="form-control" name="groups">
<option value="Main Admin">Main Admin</option>
<option value="Administrator">Administrator</option>
<option value="Content Creator">Content Creator</option>
<option value="Social Media Manager">Social Media Manager</option>
<option value="Analyst">Analyst</option>
</select>
</div>
</div>
<div class="box-footer">
Visit <a href="https://zite.pouyavagefi.com/documentation/types.php">admin types</a> documentation to know the differences between each admin.
</div>
<div class="box-footer">
<button name="submit" type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
</div>
</div>
</div>
</section>
</div>
正如您所看到的，我已经调用了一个名为 Register 的类，这个类也在这里：
<?php
class Register
{
protected $notice = array();
private $db;
public function __construct()
{
$this->db = new Connection();
$this->db = $this->db->dbConnect();
}
public function CheckUname($username,$email,$password,$groups,$level)
{
if(!empty($username)&&!empty($email)&&!empty($password)&&!empty($groups)&&!empty($level))
{
$chk1 = $this->db->prepare("SELECT user_name FROM admins WHERE user_name = ?");
$chk1->bindParam(1,$username);
$chk1->execute();
if($chk1->rowCount() == 1)
{
$notice['username_exists'] = "Try different username";
return $this->notice;
}else{
$chk2 = $this->db->prepare("SELECT email_address FROM admins WHERE email_address = ?");
$chk2->bindParam(1,$email);
$chk2->execute();
if($chk2->rowCount() == 1)
{
$notice['email_exists'] = "The email address that you have entered is already exists in database";
return $this->notice;
}else{
$this->NewAdmin($username,$email,$password,$groups,$level);
$notice['success_message'] = "New admin was successfully added";
return $this->notice;
}
}
}
}
public function NewAdmin($username,$email,$password,$groups,$level)
{
if(!empty($username)&&!empty($email)&&!empty($password)&&!empty($groups)&&!empty($level))
{
$reg = $this->db->prepare("INSERT INTO admins (user_name, email_address, password_hash, group_admin, date_joined, admin_level) VALUES ( ?, ?, ?, ?, NOW(), ?)");
$reg->bindParam(1,$username);
$reg->bindParam(2,$email);
$reg->bindParam(3,$password);
$reg->bindParam(4,$groups);
$reg->bindParam(5,$level);
$reg->execute();
}
}
public function getNotice()
{
return $this->notice;
}
}
?>
所以看起来基本上很好而且很完美，但唯一的问题是，每当我尝试在表单中提交时，我都会收到此错误：
未定义的变量：第22行的admin_new.php中的组
admin_new.php的第 22 行是这样的：
$notice = $registration->CheckUname($username,$email,$password,$groups,$level);
因此，您可以在代码中看到我已经定义了 $ groups 变量，并且它在表单中获取了 groups 值。因此，我真的不知道为什么会出现这个错误？！
所以如果你知道我该怎么做或者我的错是什么，请告诉我。我真的很感激。感谢

您收到此错误，因为$ group in call
$notice = $registration->CheckUname($username,$email,$password,$groups,$level);
$groups以不同的编码编写，并且具有非ASCII字符。可能一个或多个字母使用不同的语言类型。只需在常规拉丁语中键入或从上面提到的变量之一进行复制即可。
这应该可以解决问题。
编辑： 除了未来的问题，如果您遇到类似问题，只需将代码转换为ASCII编码并返回UTF-8，所有非ASCII字符将被替换为一些通用替换，如下划线或问号

在以下功能中，您使用var
MyEdit: TEdit;
begin
MyEdit:= TEdit(CreateThing(Panel, TEdit));
代替$groups1＆gt;＆gt;使用$groups进行更新。
$groups
