Question

我正在尝试使用php和dhtmlxform构建登录。我的表单信息成功提交到我的login.php脚本以检查凭据。如果它们是正确的，则创建用户会话，并且脚本将响应发送回dhtmlxform中的javascript。如果会话已创建，我将$ session设置为true并将响应返回给javascript。如果响应等于1，则我将用户重定向到登录页面。如果响应不是1，我会提醒响应（包含失败错误）。我需要做的是将login.php脚本中的实际$ _SESSION信息与javascript中的重定向结合起来。我该怎么做呢？

感谢所有帮助！谢谢！

我的代码：

HTML /使用Javascript：

 <body>

 <div id="headerDiv">
    <br/>
    <br/>

    <h1>Welcome to the Scheduler</h1>

    <br/>
    <br/>

</div>

<div id="bodyDiv">


    <div id="login"></div>

    <br/>
    <br/>

</div>
<script>


    loginStructure = [
        {type:"settings", position:"label-top"},
        {type:"fieldset", name: "loginFieldset", label: "Login", width: 200, list: [
            {type: "input", name: "username", label: "Username: "},
            {type:"password", name: "password", label: "Password: "},
            {type:"button", name: "submit", width: 50, offsetTop: 20, offsetLeft: 55, value: "Submit"}

        ]}

    ];



    var myForm = new dhtmlXForm("login",loginStructure);

    myForm.attachEvent("onButtonClick",function(id){
        if(id=="submit"){
            myForm.send("login.php", "post", function(loader, response){
                if (response == 1) {
                    window.location.href="https://ltiws.com/scheduler/production_sched.php";
                } else {
                    alert(response);
                };
            });
        }
    });

</script>

</body>

我的PHP脚本：

<?php

include("inc.php");


if ((isset($_POST['username'])) and (isset($_POST['password']))) {

    $login = $_POST['username'];
    $pass = $_POST['password'];

} else {
    echo "Credentials did not save. Please try again.";
}


$conn = new mysqli($servername, $username, $password, $dbname);


if ($conn->connect_errno) {
    echo "There was a problem connecting to MySQL: (" . $conn->connect_errno . ") " . $conn->connect_error;
}


$sql = "SELECT * FROM sched_users WHERE login = ? ORDER BY login LIMIT 1";

if (!($sql = $conn->prepare("SELECT * FROM sched_users WHERE login = ? ORDER BY login LIMIT 1"))) {
    echo "Prepare failed: (" . $conn->errno . ") " . $conn->error;
}


if (!($sql->bind_param("s", $login))) {
    echo "Binding parameters failed: (" . $sql->errno . ") " . $sql->error;
}


if (!$sql->execute()) {
    echo "Execute failed: (" . $sql->errno . ") " . $sql->error;
}


$res = $sql->get_result();


if ($res->num_rows === 0) {

    echo "No user record found.";

} else if (!(($res->num_rows === 1) or ($res->num_rows === 0))) {

    echo "Too many results returned.";

} else {

    $row = $res->fetch_array();

    $hash = $row['password'];

    if (password_verify($pass, $hash)) {

        session_start();

        $_SESSION['id'] = $row['id'];
        $_SESSION['firstname'] = $row['firstname'];
        $_SESSION['lastname'] = $row['lastname'];
        $_SESSION['login'] = $row['login'];
        $_SESSION['email'] = $row['email'];
        $_SESSION['phone'] = $row['phone'];
        $_SESSION['company'] = $row['company'];
        $_SESSION['department'] = $row['department'];
        $_SESSION['admin'] = $row['admin'];
        $_SESSION['statusflag'] = $row['statusflag'];
        $_SESSION['revoked'] = $row['revoked'];

        if (isset($_SESSION['id'])) {
            $session = true;
            echo $session;
        } else {
            $session = false;
            echo $session;
        }


    } else {
        echo "The username or password does not match. Please try again.";
    }
}


$sql->close();
$conn->close();

?>
