javascript - 使用模式对话框登录表单让我登录 php 函数

Question

我想要做的是，当我选中对话框中的复选框按钮时，我在其中输入的电子邮件和密码将被保存并重定向到 profile.php。

我的问题是它不起作用，并且输入框中出现错误:

Undefined index: unm and Undefined index: pwd

这里有人可以帮助我解决我的问题吗？

PHP:

<?php
if(isset($_POST['login'])) {
    if(isset($_POST['chkbox'])) {
        setcookie("unm",$_POST['email'],time()+3600);
        setcookie("pwd",$_POST['password'],time()+3600);
    }
    ?>
    <script type="text/javascript">
        window.location="profile.php";
    </script>
    <?php
}
?>

HTML:

<a data-toggle="modal" href="#myModal"><span class="glyphicon glyphicon-user"></span> Login</a>

        <div class="container">
            <div class="row">
                    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-hidden="true">
                        <div class="modal-dialog">
                            <div class="modal-content">

Answer 1

首先检查 $_COOKIE['pwd'] 或 $_COOKIE['unm'] 在 html 中设置，然后再回显它们:

if(isset($_COOKIE['pwd']) && !empty($_COOKIE['pwd'])){
    $pwd = $_COOKIE['pwd'];
}else{
    $pwd = '';
}
//same for unm 

if(isset($_COOKIE['unm']) && !empty($_COOKIE['unm'])){
    $unm = $_COOKIE['unm'];
}else{
    $unm = '';
}

那么输入应该是:

<input type="text" name="email" value="<?php echo $unm ?>" class="form-control" placeholder="Enter Email Address..." />                                    
 //same for pass 
<input type="password" name="password" value="<?php echo $pwd ?>" class="form-control" placeholder="Enter Password..." /> 

下一步不要在 cookie 中存储用户详细信息! 。如果这样做，请使用散列字符串。
