Question

这是我成功输入登录名和密码后的代码

<?php session_start();
if(!isset($_SESSION['nik'])){ die("Anda belum login");} 
if($_SESSION['level']!="admin"){ 
echo "<h3>Welcome ".$_SESSION['nik']."</h3>";
echo "panel user";
} 
if($_SESSION['level']="admin"){
echo "panel admin";
}
?>
<a href=log.php?op=selesai>Log Out</a>

我想要的输出是：如果login = admin则显示“hello admin” 如果login = user则显示“hello user” 如果没有登录，则说“你必须登录”

任何建议如何解决这个问题？

Answer 1

请根据您的要求查找以下代码。

<?php 
  session_start();
  if(!isset($_SESSION['nik'])){ 
      echo "You must login.";
      exit;
  } 
  if($_SESSION['level']!="admin"){ 
              echo "<h3>Welcome ".$_SESSION['level']."</h3>";
              echo '<a href=log.php?op=selesai>Log Out</a>';
              exit;
  }
  else {
       echo "<h3>Welcome ".$_SESSION['level']."</h3>";
       echo '<a href=log.php?op=selesai>Log Out</a>';
  }
?>

感谢。

Use following statement to set session for username while login-

    session_start();
    //following statement will create a session store user name.You can use this variable to display particular output.
    $_SESSION["uname"] = $_GET['un'];
    //in above statement 'un' is text box from which we are accepting username.

为用户名设置会话变量后，您可以在另一个页面上使用它 -

session_start();
if(isset($_SESSION["uname"]) )
{
   if($_SESSION["uname"] == 'admin')
   {
     echo 'hello admin';
   }
   else($_SESSION["uname"] == 'uname')
   {
      echo 'hello user';
   }
}
else
{
echo "you must login"
}

Answer 4

问题在于您的操作员选择。

if($_SESSION['level']="admin"){
echo "panel admin";
}

应该是

if($_SESSION['level'] == "admin"){
echo "panel admin";
}

=是一个赋值运算符。您需要使用==或===
