问题
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=$1
回答1:
You need to include the QSA flag at the end of your rule. This appends any existing query string to the one that you're constructing in the rule itself:
RewriteEngine On
RewriteRule ^category/([0-9]+)/[a-z][-a-z0-9]*$ cat.php?id=$1 [L,QSA]
So the rewritten URI should end up being: /cat.php?id=23&page=3
回答2:
Add QSA(query string append) at the end of your rewrite rule.
RewriteEngine On
RewriteRule ^category/([0-9]+)/[a-z][-a-z0-9]*$ cat.php?id=$1 [L,QSA]
When the replacement URI contains a query string, the default behavior of RewriteRule is to discard the existing query string, and replace it with the newly generated one. Using the [QSA] flag causes the query strings to be combined.
With the [QSA] flag, a request for /pages/123?one=two will be mapped to /page.php?page=123&one=two. Without the [QSA] flag, that same request will be mapped to /page.php?page=123 - that is, the existing query string will be discarded.
