mod_rewrite如何保存查询字符串？

Question

I have been looking all over the internet but I just can't find a solution.

I've been trying to pass a query string as another $_GET value in php. For example localhost/find/book translates to index.php?url=find/book but that's not enough for my purpose. When I try to do something like localhost/find/book?cols=name,library I want this to translate to index.php?url=find/book?cols=name,library but instead it translates to index.php?url=find/book it just omits the second query string.

I'm pretty sure that I did this a couple of months ago and it worked. But now it just doesn't and I don't know why.

Here are my rewrite rules:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l

RewriteRule ^(.*)$ index.php?url=$1 [L,QSA]

Thanks in advance.

Answer 1

The QSA option that you are already using does just that.

However, there is no such thing as a second query string, so you url will not translate to:

index.php?url=find/book?cols=name,library

but instead to something like:

index.php?url=find/book&cols=name,library
                       ^ here

Note that you have to take care that you output valid query strings (using for example urlencode in php) as otherwise your application might not behave as you think it should. Your comma for example should be encode as %2C but you should let urlencode take care of that.
