网站根相对路径无效 [英] Site-root relative path doesn't work

问题描述

我不明白这一点.因为我使用的是php模板，所以整个网站搞砸了.

I'm not understanding this. It's screwing up whole site because I'm using a php template.

根据我已阅读的每篇文章，假定以'/'开头的链接使我从根开始.但是，当我以'/'开头时，它根本不起作用.

Supposedly beginning a link with '/' starts me at the root according to every article I've read. However, when I begin with '/' it doesn't work at all.

我的变量位于

public_html/cis130/textfiles/php/variables.php

我的template.php文件位于

My template.php file is in

public_html/cis130/textfiles/php/template.php

我的index.php文件位于

My index.php file is located at

public_html/cis130/index.php

它在我的index.php文件中读取，

In my index.php file it reads,

<?php  
  require('/cis130/textfiles/php/variables.php');  
  $currentpage = $page[0];  
  require('/cis130/textfiles/php/template.php');  
?>

它不起作用...我得到致命错误:require():无法打开所需的'/cis130/final/textfiles/php/variables.php'(include_path ='.:/usr/local/php54/pear')，位于第3行的/home/philumpt/public_html/cis130/final/index.php中

It doesn't work... I get "Fatal error: require(): Failed opening required '/cis130/final/textfiles/php/variables.php' (include_path='.:/usr/local/php54/pear') in /home/philumpt/public_html/cis130/final/index.php on line 3"

如果我使用相对链接，

textfiles/php/file.php

然后它可以工作，但仅适用于index.php.我的其他页面位于"public_html/cis130/textfiles/pages/"中.如果那很奇怪，那是我班上的老师让我们做的.

then it works, but only for index.php. My other pages are located in 'public_html/cis130/textfiles/pages/'. If that's weird, it's what the teacher in my class is making us do.

推荐答案

只需将基本路径集用作配置，就不必担心相对路径，这样您就不会不断地在变相对位置.例如，在主配置文件中，您可以定义如下基本路径:

Stop worrying about relative path by just using a base path set as a configuration so you are not constantly juggling relative locations. For example, in your main config file, you can define a base path like this:

$BASE_PATH = '/the/path/to/the/codebase/';

如果您不知道文件的基本路径，请将此行放在PHP代码的顶部:

If you don’t know the base path to your files, then place this line at the top of your PHP code:

echo "Your path is: " . realpath(dirname(__FILE__)) . "<br />";

并加载该页面.顶部附近的某行应显示为:

And load that page. Somewhere near the top should be a line that reads:

您的路径是:/the/path/to/the/codebase/

Your path is: /the/path/to/the/codebase/

当然/the/path/to/the/codebase/将是您的实际文件路径，但这将是您的基本路径.然后只需将 $ BASE_PATH 设置为该值.

Of course /the/path/to/the/codebase/ will be your actual file path, but that will be your base path. Then just set $BASE_PATH to that value.

然后，当您执行 require 时，语法为:

Then when you do an require, the syntax would be:

require($BASE_PATH . '/cis130/textfiles/php/variables.php');

这样做的好处是，无论代码库嵌套的深度如何，您始终将锚定在 $ BASE_PATH 的值上.不必担心相对路径问题，您的生活将变得更加轻松.

The benefit of this is no matter how deeply nested your codebase becomes, you will always be anchored to the value of $BASE_PATH. And your life will be made tons easier thanks to not having to worry about relative path issues.

我还建议使用 require_once 而不是 require 以避免脚本可能无意间尝试多次加载同一文件的情况.

I would also recommend using require_once instead of require to avoid scenarios where your script might inadvertently attempt to load the same file more than once.

require_once($BASE_PATH . '/cis130/textfiles/php/variables.php');
