Php 执行登录时重定向无法正常工作

代码：

$（文档）.ready（函数（）{
$（“#登录”）。单击（函数（事件）{
event.preventDefault（）；
elogin=$（“#elogin”）.val（）；
plogin=$（“#plogin”）.val（）；
$.ajax({
类型：“POST”，
数据：{“elogin”：elogin，“plogin”：plogin}，
url:“candidate.php”，
成功：功能（数据）{
$（“.login_success”）.html（数据）；
}
});
});
});

candidate.php

<script>
    $(document).ready(function(){
        $("#login").click(function(event){
            event.preventDefault();
            elogin = $("#elogin").val();
            plogin = $("#plogin").val();
            $.ajax({
                type:"POST",
                data:{"elogin":elogin,"plogin":plogin},
                url:"candidate.php",
                success:function(data){
                    $(".login_success").html(data);
                }
            });
        });
    });
</script>
<div class="login_success"></div>   
<form class="loginLay" id="myform">
    <input type="text" name="elogin" id="elogin" class="form-control1" placeholder = "Enter Your Email"/>
    <input type="text" name="plogin" id="plogin" class="form-control1" placeholder = "Enter Your Password"/>
    <a href="javascript:void(0)" id="forgot">Forgot Password</a>
    <center>
        <input type="submit" name="login" id="login" class="btn btn-primary"/>
    </center>
</form>

试试这个

<?php
    session_start();
    include('config.php');

    $email = $_POST['elogin'];
    $password = $_POST['plogin'];
    $sql = "select * from student where email = '$email' and password = '$password' and status = 'enable'";
    $result = mysqli_query($con,$sql);
    $num_rows = mysqli_num_rows($result);
    if($result)
    {
        if ($num_rows > 0) 
        {
            $sqls = "select * from student where email = '$email' and password = '$password'";
            $results = mysqli_query($con,$sqls);
            while ($rows = mysqli_fetch_assoc($results)) 
            {
                $_SESSION['student_id'] =  $rows["id"];

            }
            header ("Location: student/dashboard.php");
        }
        else 
        {
            echo "<p id='red'>Wrong email or password or may be your account not activated.</p>";
        }   
    }
?>



JS:


$（文档）.ready（函数（）{
$（“#登录”）。单击（函数（事件）{
event.preventDefault（）；
elogin=$（“#elogin”）.val（）；
plogin=$（“#plogin”）.val（）；
$.ajax({
类型：“POST”，
数据：{“elogin”：elogin，“plogin”：plogin}，
url:“candidate.php”，
成功：功能（数据）{
if（数据类型！=='object'）{
data=JSON.parse（数据）；
}
if（data.redirect）{
窗口.位置.替换（数据.重定向）；
}否则{
$（“.login_success”）.html（“
”+data.error+”
”）；
}
}
});
});
});

正确的方法是从客户端重定向，而不是通过服务器重定向

在这种情况下是行不通的

尝试从服务器发送一些响应，并根据需要通过window.location.href重定向

您需要在登录后在会话中维护一个值，并在仪表板中检查该值。
该值可能重复
<?php
    session_start();
    include('config.php');

    $email = $_POST['elogin'];
    $password = $_POST['plogin'];
    $sql = "select * from student where email = '$email' and password = '$password' and status = 'enable'";
    $result = mysqli_query($con,$sql);
    $num_rows = mysqli_num_rows($result);
    if($result)
    {
        if ($num_rows > 0) 
        {
            $sqls = "select * from student where email = '$email' and password = '$password'";
            $results = mysqli_query($con,$sqls);
            while ($rows = mysqli_fetch_assoc($results)) 
            {
                $_SESSION['student_id'] =  $rows["id"];

            }
            if (!isset($_POST)) {
                header ("Location: student/dashboard.php");
            } else {
                echo json_encode(array('redirect' => 'student/dashboard.php'));
            }
        }
        else 
        {
            echo json_encode(array('error' => 'Wrong email or password or may be your account not activated.'));
        }
    }
?>
