Question

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

我的问题是它无法正常工作，输入框中出现错误：

未定义索引：unm和未定义索引：pwd

这里有人可以帮我解决问题吗？

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">

首先检查是否在回复它们之前在html设置$ _COOKIE [＆＃39; pwd＆＃39;]或$ _COOKIE [＆＃39; unm＆＃39;]：

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 = '';
}

然后输入应为：

<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..." />

接下来，不要将用户详细信息存储在Cookie中！。如果这样做，请使用散列字符串。
