php - 注册表格的电子邮件激活

Question

我有注册表单，我希望用户必须在用户激活他们的电子邮件后激活他们的电子邮件，然后用户才能登录他们的帐户，否则用户无法登录？

问题

问题是用户不激活邮箱也能登录？

代码

$email2=$_POST['email'];
$querycheck=mysql_query("select activation from students 
                         where semail='$email2'") or die ("Query Activated Problem");
$rowcheck=mysql_fetch_array($querycheck);
$act=$rowcheck['activation'];

if($act=='activated')
  {

    $email=$_POST['email'];
    $password=$_POST['password'];
    $email = stripslashes($email);
    $password= stripslashes($password);
    $email = mysql_real_escape_string($email);
    $password = mysql_real_escape_string($password);

    $querymysql=mysql_query("select * from students where semail='$email'
                             and spassword='$password'  ") or die ("query problem");
    $row=mysql_fetch_array($querymysql);


    if($row)
      {

        session_register("email");
        session_register("password"); 

        header('Location:index.php');   
      }
    else {
      $message="Please Check Your Login Details";   
      header('Location:login.php?login_error='.$message.'');    
    }

  }
else if($act=='')
  {
    $actmsg="Your Email Is Not Activated Yet";  
    header('Location:login.php?actmsg='.$actmsg.'');        
  }

session_register :此函数已从 PHP 5.3.0 开始弃用并从 PHP 5.4.0 开始删除。

直接使用$_SESSION设置变量。
