Nginx Replace Query string redirect

We were running on apache previously and used the below code to redirect/replace one of our query parameters.

RewriteCond %{QUERY_STRING} ^limit=(.*)$ [NC]
RewriteRule ^ %{REQUEST_URI}?product_list_limit=%1 [L,R=301]

This would successfully redirect the below URL

www.example.com/clothing.html?limit=all

TO

www.example.com/clothing.html?product_list_limit=all

I have used a htaccess redirect convertor that has produced the below. This doesn't work

    location ~ / {
    if ($query_string ~* "^limit=(.*)$"){
        rewrite ^(.*)$ /$request_uri?product_list_limit=%1 redirect;
    }
}

Any help appreciated

Thanks

You should not use $request_uri to construct the rewritten URI, as it also contains ?limit=all - so your rewritten URI would look like: /clothing.html?limit=all?product_list_limit=all

The rewrite statement resets numeric captures, so you will need to use a named capture in the if statement.

The URI without query string is available as $uri or as a capture from the rewrite statement's regular expression.

Either of these forms should work for you:

if ($query_string ~* "^limit=(?<limit>.*)$") {
    rewrite ^(.*)$ $1?product_list_limit=$limit? redirect;
}

Note the trailing ? to prevent the original query string from being appended. See this document for more.

Or:

if ($query_string ~* "^limit=(.*)$") {
    return 302 $uri?product_list_limit=$1;
}

The value of the limit argument is also available as $arg_limit, so you could also use this:

if ($arg_limit) {
    return 302 $uri?product_list_limit=$arg_limit;
}

See this document for details.
