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\'

Answer 1

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'] ) ) { ... }
