如何将url参数添加到当前url？ [英] How to add url parameter to the current url?

问题描述

目前我在 http://example.com/topic.php?id=14 ，我想要链接到 http://example.com/topic.php?id=14&like=like 通过不定义当前网址。像< a href =& like = like>就像< / a> 。然而，最后一个显示我 http://example.com/&like=like

解决方案

你必须：

  topic.php？id = 14& like = like 
  

Currently I'm at http://example.com/topic.php?id=14 and I want to make a link to http://example.com/topic.php?id=14&like=like by not defining the current url. Like <a href="&like=like">Like</a>. However this last one shows me http://example.com/&like=like

解决方案

There is no way to write a relative URI that preserves the existing query string while adding additional parameters to it.

You have to:

topic.php?id=14&like=like
