问题描述

所以这是我第一次使用 xampp 创建测试站点.我最初将所有 php 文件放在一个文件夹中，最近才决定组织数据(是的，事后看来，我应该从有组织的文件夹结构开始.)无论如何，我的设置如下:

So this is my first time creating a test site with xampp. I originally had all my php files in one folder and just recently decided to organize the data (yes, hindsight i should've started with an organized folder structure.) Anyways, I have my setup like this:

" [ ] " 表示它是一个文件夹

" [ ] " implies it is a FOLDER

安装在我的 C: 驱动器上

Installed on my C: drive

[xampp]
└── [htdocs]
    └── [QMS]
        └── [rev3]
            ├── [css]
            ├── [js]
            ├── [DPU]
            ├── [login]
            ├── index.php
            ├── header.php
            └── config.php

在我的config.php"文件中，我尝试定义一个根路径(这可能是错误):

In my "config.php" file I tried to define a root path (this may be the error):

$path = $_SERVER['DOCUMENT_ROOT'] . "/QMS/rev3/";

然后在我的 header.php 文件中我有:

Then in my header.php file I have:

<?php
require $_SERVER['DOCUMENT_ROOT'] . "/QMS/rev3/config.php";
include $_SERVER['DOCUMENT_ROOT'] . "/QMS/rev3/login/session.php";
.....
?>

HTML - located in the <head> section

<link rel='stylesheet' type='text/css' href='<?php echo $path . "css/searchBar.css"; ?>'/>
<link rel='stylesheet' type='text/css' href='<?php echo $path . "css/tables/filtergrid.css"; ?>'/>
<script type="text/javascript" language="javascript" src='<?php echo $path . "js/jquery.dataTables.js" ?>'></script>
<script type="text/javascript" language="javascript" src='<?php echo $path . "js/jquery.loader.js" ?>'></script>

... MANY OTHER scripts and stylesheets.

.我的 index.php 是:

. My index.php is:

require $_SERVER['DOCUMENT_ROOT'] . "/QMS/rev3/header.php";

当我在 Chrome 中启动它时 - 我的所有脚本和样式表都出现以下错误(总共 19 个错误):

When I launch this in Chrome - I get the following errors for ALL of my scripts and stylesheets (19 errors total):

"NOT ALLOWED TO LOAD LOCAL RESOURCE  file///C:/xampp/htdocs/QMS/rev3/ ......etc..."

当我的所有文件都在同一个文件夹中并且我没有使用 SERVER['DOCUMENT_ROOT'] 时，我的网站运行良好，但现在我不知道该怎么办......有什么建议吗?

My site was working perfectly when all my files were in the same folder and I wasn't using SERVER['DOCUMENT_ROOT'], but now I have no idea what to do...any advice?

推荐答案

不允许加载本地资源

你在<a>、<link>、<script>等标签中使用的url应该是相对的文档根目录，例如:

The url you use in <a>, <link>, <script>, etc tags should be relative to the document-root, eg:

<link rel="stylesheet" type="text/css" href="/QMS/rev3/css/searchBar.css" />

不要将磁盘上的路径与url的混淆，它们是两个完全不同的东西:)

Don't confuse paths on disk with url's, they're two completely different things :)

建议确定根路径

我建议不要依赖 $_SERVER['DOCUMENT_ROOT'] 变量，而是像这样确定根文件夹(在 config.php 中):

I recommend not to rely on the $_SERVER['DOCUMENT_ROOT'] variable, but determine the root-folder like this (in config.php):

define('ROOT_PATH', __DIR__);

您将拥有一个名为 ROOT_PATH 的常量，其中将包含 C:xampphtdocsQMS ev3(没有尾随 /).

You'll have a constant named ROOT_PATH which will contain C:xampphtdocsQMS ev3 (without a trailing /).

现在您可以执行以下操作:

Now you can do things like:

require ROOT_PATH . '/header.php';

ROOT_PATH 中的路径与文档根目录不同.如果您真的想使用文档根目录，请执行此操作(这样 ROOT_PATH 将包含 C:xampphtdocs):

The path in ROOT_PATH differs from the document-root. If you really want to use the document-root, do this (so that ROOT_PATH will then contain C:xampphtdocs):

define('ROOT_PATH', __DIR__ . '/../..');

# ...

require ROOT_PATH . '/QMS/rev3/header.php';

规范化的绝对路径名

使用 Capsule 中提到的 realpath() 可能是明智的(展开所有符号链接和解析对 /./、/../ 和额外 / 字符的引用):

It might be wise to use realpath() as mentioned by Capsule (expand all symbolic links and resolve references to /./, /../ and extra / characters):

$rootPath = __DIR__ . '/../..';  # or just __DIR__
$realPath = realpath($rootPath);
define('ROOT_PATH', $realPath ?: $rootPath);

如果 realpath() 无法解析路径，它将返回 false，这就是为什么要进行一些检查.

If realpath() fails to resolve the path it will return false, that's why there's a little check.
