Question

我需要某人的专业知识。一旦用户登录....如果他们试图返回登录页面，我希望将它们重定向到另一个php页面。现在我的用户仍然可以登录，但也可以返回登录表单。

<?php

if(isset($_POST['login'])){

session_start();

$password = $_POST['pass'];
$email = $_POST['email'];

$user_pass= md5($user_pass);

$check_user = "select * from userss where user_pass='$password' AND user_email='$email'";

$run = mysql_query($check_user);

if(mysql_num_rows($run)>0){

$_SESSION['email']=$email;

echo "<script>window.open('welcome.php','_self')</script>";
}
else {
echo "<script>alert('Email or password is incorrect!')</script>";
   }

}

?>

Answer 1

这类问题已经得到解答。见How to make a redirect in PHP?

在提供任何页面之前，您已经在检查用户的登录状态。正确？

if (logged_in){
  header("Location: http://example.com/myOtherPage.php");
  die();
}

试试这个。

此processlogin.php编写此代码：

if(isset($_POST['login'])){
    session_start();
    $password = $_POST['pass'];
    $email = $_POST['email'];
    $user_pass= md5($user_pass); 
    $check_user = "select * from userss where user_pass='$password' AND user_email='$email'";
    $run = mysql_query($check_user);
    if(mysql_num_rows($run)>0){ 
        $_SESSION['email']=$email; 
        echo "<script>window.open('welcome.php','_self')</script>";
    } else { 
        echo "<script>alert('Email or password is incorrect!')</script>"; 
    } 
}

在login.php中

写下这段代码：

    <?php 
if(session_start()){
       echo "<script>window.open('welcome.php','_self')</script>";
    }else{ ?>
       <form method='post' action='processlogin.php' class="form-signin">
           <h2 class="form-signin-heading">Login </h2>
           <label for="inputEmail" class="sr-only"></label>
           <input type="email" id="inputEmail" name="email" class="form-control" placeholder="Email address" required autofocus><br>
           <label for="inputPassword" class="sr-only"></label>
           <input type="password" id="inputPassword" name="pass" class="form-control" placeholder="Password" required><br/>
           <button type="submit">LOGIN</button>
       </form>
    <?php } ?>

希望这可以提供帮助。
