为什么我的超链接转到错误的目录？ [英] Why do my hyperlinks go to the wrong directory?

问题描述

在我的项目中，功能就像我需要设置一个链接以指向：

  / site / sales / sold .php 
  

因此menu.php文件链接如下所示：

 < ul> 
< li>< a href =sales />销售< / a>< / li> 
< li>< a href =sold.php>已售物品< / a>< / li> 
< / ul> 
  

有时会直接转到
<$ p $在下一刻，我们就可以看到，在一段时间内，我们可以看到，它重复菜单的目录，如：

  /site/sales/sales/sold.php 
  $ b    
 $ b 
  /site/sold.php 
  
 
 
 
  
如果您在页面上<$ c $ 
 
 c> sales / 并链接到页面 sales ，链接将导致 sales / sales /  
 
避免这种情况的默认方法是通过HTML < base>指定一个基本URL。 标签。这里没有涉及PHP，JS或CSS  - 只是好的HTML 2.0。
 < base href =http： //www.example.com/site/\"> 
  
在你的页面头部使用这个，将给定的URL定义为页面上所有链接的基础，因此像 sales / 这样的链接实际上会导致 http://www.example.com/site/sales/ 当点击。

In my project functionality is like when i need to set a link to direct to:
/site/sales/sold.php
so the menu.php file link would look like this:
 <ul>
      <li><a href="sales/">Sales</a></li>   
      <li><a href="sold.php">Sold Items</a></li>
    </ul>
it would sometime direct to 
/site/sales/sold.php 
and the next moment, it repeats the menu's directory like: 
/site/sales/sales/sold.php
so i removed the sales directory, as its directing there by itself, worked for a little while and now it directs to 
/site/sold.php
which does not exist so it ends up with a 404.
解决方案
If you are on a page sales/ and link to a page sales, the link will result in sales/sales/ – that is the defined behavior.

The default method to avoid that is to specify a base URL via the HTML <base> tag. There is no PHP, JS or CSS involved here – just good ol' HTML 2.0.
<base href="http://www.example.com/site/">
Using this in your pages head, will define the given URL as base for all links on the page, thus a link like sales/ will actually result in http://www.example.com/site/sales/ when clicked.
