我有一个明确的URL为基础的系统，以便类别将显示像这样

  http://www.mysite.com/category/23/cat-name
 

在类别页面我有一些的排序和网页选项，如通过latests和更低的价格排序。另外，我有一个页面导航系统

现在的问题是，当请求发生在页面内的 $ _ GET [] 不显示我需要的变量。然而，它示出在URL为

  http://www.mysite.com/category/23/cat-name?page=3
 

在 $ _ GET 变量只能说明这是在我们的例子现在= 23 而忽视了类的ID页码是在URL中。

的.htaccess 内容

  RewriteEngine叙述上
重写规则^类/（[0-9] +）/ [AZ] [ -  A-Z0-9] * $ cat.php ID = $ 1
 

解决方案

您需要包含的 QSA 把你的统治结束。这追加任何现有的查询字符串，你构建的规则本身之一：

  RewriteEngine叙述上
重写规则^类/（[0-9] +）/ [AZ] [ -  A-Z0-9] * $ cat.php ID = $ 1 [L，QSA]
 

于是重写URI应该结束了是： /cat.php?id=23&page=3

I am have a clear URL based system so the categories will be shown like this

http://www.mysite.com/category/23/cat-name

Inside the categories page I have some sorting and pages options such as sorting by latests and lower price. Also, I have a pages navigation system

The problem is when the request is happening inside the page the $_GET[] doesn't show the variables I need. However it shows in the URL as

http://www.mysite.com/category/23/cat-name?page=3

The $_GET variable only shows the id of the category which is in our case now = 23 and ignored the page number which is in the url.

.htaccess content

RewriteEngine On
RewriteRule ^category/([0-9]+)/[a-z][-a-z0-9]*$ cat.php?id=$1

You need to include the QSA flag at the end of your rule. This appends any existing query string to the one that you're constructing in the rule itself:

RewriteEngine On
RewriteRule ^category/([0-9]+)/[a-z][-a-z0-9]*$ cat.php?id=$1 [L,QSA]

So the rewritten URI should end up being: /cat.php?id=23&page=3
