Weird Undefined Variable Error

Question

Kommen wir direkt zu dem Problem. Ich habe diese Form:

<?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); 
    } 
} 
?>

Wie Sie sehen, ich habe Aktionsdatei direkt an der Spitze hinzugefügt und alles sieht gut aus und groß. Aber das Problem ist ich diese seltsame Fehlermeldung erhalten:

Undefined variable: Gruppen auf der Leitung 22

Und das ist Zeile 22:

$notice = $registration->CheckUname($username,$email,$password,$groups‌​,$level);

Es ist sehr seltsam aber, weil es bereits passiert hat durch die POST Methode und hat Wert.

Also wenn Sie wissen, warum bekomme ich das, lass es mich wissen .. danke!

AUCH: Wenn Sie Register.class.php einen Blick auf die Klasse nehmen müssen, die ich früher verwendet haben, können Sie es hier finden:

<?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; 
    } 
} 
?> 

Answer 1

Wie wäre es eine Möglichkeit um zu tun. Ihr Code wie folgt ..

$registration = new Register(); 

$dataArray = array(
    'username'=>$username, 
    'email'=>$email, 
    'password'=>$password, 
    'groups‌'=>$groups‌, 
    'level'=>$level 
); 

$notice = $registration->CheckUname($dataArray); 

Und Funktion wie diese

public function CheckUname($dataArray)
