PHP $_POST 不起作用 [英] PHP $_POST not working
问题描述
我正在学习有关 $_POST 的 PHP 教程，它让我创建了一个包含两页的练习.在第一页(表单页面)上，它会创建一个表单，用户可以在其中输入用户名和密码.单击提交后，它会在第二页 (process.php) 上打开，其中应显示用户名和密码，这是使用 $_Post 的结果.但是，当我在第一页上单击提交时，它会将我带到第二页，其中只显示 Echo 语句中的:".没有用户名，没有密码.
I'm following a PHP tutorial which is teaching about $_POST and it had me create an exercise with two pages. On the first page (Form page) it creates a form where a user enters Username and Password. Once they click submit, it opens on the second page (process.php) where the Username and Password should be displayed as a result of using $_Post. However, when I click submit on the first page, it takes me to the second page where only the ":" in the Echo statement is displayed. No username, no password.
有什么想法吗?我已经复制了表单页面和下面的 process.php.
Any ideas? I've copied the form page and the process.php below.
Form page
<html>
<head>
<title>encode</title>
</head>
<body>
<form action="process.php" method="post">
Username: <input type="text" name="username" value="" />
<br/>
Password: <input type="password" name="password" value=""/>
<br/>
<input type="submit" name="submit" value="Submit"/>
</form>
</body>
</html>
进程.php
<html>
<head>
<title>encode</title>
</head>
<body>
<?php
$username = $_Post['username'];
$password = $_Post['password'];
echo "{$username}: {$password}";
?>
</body>
</html>
推荐答案
尝试使用 $_POST(全部大写).
Try using $_POST (all caps).
函数不区分大小写，但变量不区分.
Functions are case insensitive, but variables aren't.
