Question

的index.php

<?php
session_start();
if(isset($_SESSION['usr'])){
header("Location: browse.php");
}
?>
<!DOCTYPE html>
<html>
    <body>

                        <form class="form col-md-12 center-block" action="login.php" method="post">
                            <div class="form-group">
                                <input type="text" class="form-control input-lg" placeholder="Email" name="mail" required="true">
                                    </div>
                            <div class="form-group">
                                <input type="password" class="form-control input-lg" placeholder="Password" name="pass" required="true">
                                    </div>
                            <div class="form-group">
                                <input type="submit" name="Signin" value="Sign In" class="btn btn-primary btn-lg btn-block">
</div>
                      </form>
    </body>
</html>

的login.php

<?php
session_start(); // Starting Session
$error=''; // Variable To Store Error Message
if (isset($_POST['Signin'])) {
$con=mysqli_connect(********);
    if (!$con)
    {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }
        $mail=isset($_POST['mail']) ? $_POST['mail']:null;
        $pass=isset($_POST['pass']) ? $_POST['pass']:null;

        $sql2 = "SELECT mail, password FROM user_data where mail='$mail' and password='$pass'";
$result = mysqli_query($con, $sql2);

if(mysqli_num_rows($result) == 1){
$_SESSION['usr']=$mail; 
mysql_close($con); // Closing Connection
header("Location: browse.php");
}
else {
header("Location: index.php");
}
}
?>

Browse.php

<?php
session_start();
if(!isset($_SESSION[‘usr’])){
    header("Location: index.php");
}
?>
<html>
<!-- content here -->
<html>

在上面的代码中，index.php中的邮件值被赋予login.php中的$ _SESSION ['usr']，然后重定向到browse.php。这里，！isset（$ _ SESSION ['usr']）是真的，$ _SESSION ['usr']也没有任何内容，因此加载回index.php。我可以获得上述代码的解决方案吗？

Answer 1

你应该为$ _SESSION添加一个像这样的值

$_SESSION['user'] = 'yes';

然后在你的browse.php上

<?php
session_start();
if(empty($_SESSION['usr'])){
  echo"<script>window.open('index.php','_self')</script>";
}

希望它有所帮助。

在php登录页面后无法传递$ _SESSION ['usr']值
