我正在为一个班级制作一个网页。这是一个为即将到来的新生设计的网站，用于接收他们感兴趣的专业的信息。

对于作业，我必须将我的原始 HTML 代码分成 header.php、content.php 和 footer.php。我还必须通过 $ SERVER[PHP SELF] 的操作为我的表单使用 POST 方法。我还必须在表单中使用隐藏的输入字段。

我已经完成了所有这些任务，但我认为我的 heredoc 打印有问题 <<

我知道我的表单还有一些工作要做，但我真的很想看到页面将正确加载我的页眉、内容和页脚。由于我什么都看不到，我不想继续写出任何其他功能。请您看看我的 PHP 代码并帮我找到这个错误好吗？我确定我只是忽略了一些东西，但我会很感激你的帮助！谢谢！

头文件.php：

<!doctype html>
<html lang="en">

<meta charset="UTF-8">
<title>UNA Preview Day 2013</title>
<link rel="stylesheet" href="preview.css">
<script src="preview.js"></script>
</head>
<body>

内容.php：

<noscript>
    <p class="alert">Sorry, this page requires Javascript!</p>
</noscript>

<img src= "banner.gif" alt = "UNA Logo" />

<h1>UNA Preview Day 2013</h1>

页脚.php

    <div class = "image">
    <img src = "unapic.png" alt = "UNA Logo" />
</div>
<p id = "footer">Copyright &copy; 2013 | University of North Alabama</p>

</html>

索引.php：

<?PHP
require("header.php");

if ($_POST[_submit_check])  { 
processForm();
}
else  {

}

function displayForm()  {
require("content.php");
}

require("footer.php");

if (array_key_exists('_submit_check', $_POST))  {
processForm();
}
else  {
displayForm();
} 

// ------------------------------------------------
function processForm()  {    //NEEDS WORK
print "Hello, $_POST[user]!";
}

function display_form()  {
//require("content.php");

我在下面给你做了一些非常难看的东西。但是，是的，您需要在调用它们之前声明所有函数，因此将它们放在头文件中，甚至更好地放在单独的文件中和require_once('functions.php');头文件的最顶部。

您将函数拼写为 displayForm()，然后将 display_form() 放低。确保遵守命名约定，否则它将不起作用。

还要确保只保留 1 个标签，<html><body><title>即使您有多个文件，如果有意义的话，整个文档只需要一个。

检查是否提交时。我改为 if(isset($_POST['_submit_check']){} 但对你有用。

Netbean 是我最喜欢的文本编辑器，它可以帮助您将来进行调试。

有一个：

require("footer.php");

在创建无限循环的footer.php 中
