获取和编辑GET变量以创建超链接的方式 [英] Way to get and edit GET variables in order to make hyperlinks

问题描述

假设我的网址类似于 somefile.php？sort = id& way = desc 。

我想写一个函数（或者使用已经创建的函数）来让我添加下一个变量到URL并设置我想要删除的。

我想过类似 function editGetVar（$ add，$ leave）其中 $ add 到URL和 $ leave 将会是数组，其变量必须保留在URL中。

$ b 示例：

  somefile.php？sort = id& way = desc& buyer = retailer 
  

，我想删除买家并添加action，那么 a href 看起来像这样：

 < a href =somefile.php？sort = id& way = desc& action = edit> 
  

如果您有任何想法，我将不胜感激。

解决方案

使用 http_build_query ：

 <？php 
 unset （$ _GET [ '买方']）; 
 $ _GET ['action'] ='edit'; 
 
 print'< a href =somefile.php？'。http_build_query（$ _ GET）。'> !!< / a>'; 
？> 
  

Let's say that I have URL like somefile.php?sort=id&way=desc.

I want to write a function (or use already made one) that would let me add next variables to URL and set which I want to delete.

I thought about something like function editGetVar("$add","$leave") where $add would be array with new variables to add to URL and $leave would be array with variables that must stay in URL.

Example:

somefile.php?sort=id&way=desc&buyer=retailer

and I want to delete "buyer" and add "action", then the a href would look like this:

<a href="somefile.php?sort=id&way=desc&action=edit">

I would appreciate any ideas from you.

解决方案

Use http_build_query:

<?php
unset($_GET['buyer']);
$_GET['action'] = 'edit';

print '<a href="somefile.php?' . http_build_query($_GET) . '">!!</a>';
?>
