Wordpress simple rewrite rule not working

Question

I'm trying to create a rewrite rule in Wordpress to create direct pretty links to search results.

I'm working with a custom post type called 'object'

My result page is located at this url : http://www.domain.com/objects/

I want to create this kind of URL to point a listing of new objects : http://www.domain.com/objects/new

The rewritten query must be : http://www.domain.com/objects/?filter=new

I will then be able to use the $_GET['filter'] value to query my objects (meta_query)...

my problem

I've try to to this with this code:

add_rewrite_tag('%filter%','([^&]+)');
add_rewrite_rule('objects/new/','objects/?filter=new','top');

.htaccess looks then like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^objects/new/ /objects/?filter=new [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Unfortunately, when I try to reach the URL http://www.domain.com/objects/new I've got a 404 error :(

Debug bar show me this:

Request:
   objects/new

Query String:
   attachment=new

Matched Rewrite Rule:
   [^/]+/([^/]+)/?$

Matched Rewrite Query:
   attachment=new

Can someone tell me why Wordpress try to retrieve an attachment? Is something wrong in my rewrite rule or am I missing something?

Thanks in advance for your help!

Few Questions 1. is this working properly - domain.com/objects 2. domain.com/objects/filter/new - whether it will be ok for you ? — Pramod Kumar Sharma
Hi Pramod, I don't understand what you mean with these questions? domain.com/objects is an existing WP page, and domain.com/objects/filter/new is not a good solution for me since I don't want the "filter" in the final url (I want domain.com/objects/new) — MavBzh

OK, I've finnaly found a way to achieve this.

Here is the code I added to my theme:

function custom_rewrite( $wp_rewrite ) {
    $feed_rules = array(
        'objects/(.+)'  =>  'index.php?page_id=27&filtre=' . $wp_rewrite->preg_index(1),
    );
    $wp_rewrite->rules = $feed_rules + $wp_rewrite->rules;
}

where 27 is the Wordpress ID of the "/objects" page I want to reach with the rewritten URL, and:

function custom_wp_querystring() {
    add_rewrite_tag('%filtre%','([^&]+)');
}

In order to tell Wordpress I need to use a custom query var called "filtre".

This last function must be added on init action:

add_action( 'init', 'custom_wp_querystring');
add_filter( 'generate_rewrite_rules', 'custom_rewrite' );

Important thing to know, in my page template (the one with ID 27 in my example), if I want to test the query var, it's not possible to do that kind of test:

if ( isset ( $_GET['filtre'] ) ) { ... }

GET vars are 'hidden' due to Wordpress redirection, you must then do:

if ( isset( $wp_query->query_vars['filtre'] ) ) { ... }
