Redirection with custom rules fails

Hi,

I made some further tests to try to find a solution, but I havent’t. But perhaps this can help you to give me a piece of support.

At first I swiched back to WPML (backup) and made a call to

http://ssn.localhost/de/data/skater/nico-ihle/

The output from by error_log in template_redirect (see my last post) was:

[query_vars] => Array
        (
            [page_id] => 814
            [skater] => nico-ihle
        )
    [query_string] => page_id=814&skater=nico-ihle
    [request] => de/data/skater/nico-ihle
    [matched_rule] => de/data/skater/(.+)
    [matched_query] => page_id=814&skater=nico-ihle
    [did_permalink] => 1

I was forwarded to the correct page. Fine!

Now I turned off WPML and turned on PL and imported all posts (WPML to PL Importer)

I called now the same link and get/got:

[query_vars] => Array
        (
            [page] =>
            [pagename] => data/skater
            [lang] => de
        )

    [query_string] => pagename=data%2Fskater&lang=de
    [request] => de/data/skater
    [matched_rule] => (en|de)/(.?.+?)(/[0-9]+)?/?$
    [matched_query] => lang=de&pagename=data%2Fskater&page=
    [did_permalink] => 1

it redirects me to http://ssn.localhost/de/data/skater/.

As you can see, there is no more skater parameter in query_vars. My custom rule isn’t been used.

Next I checked my rewrite rules using the Rewrite analyzer plugin. There I entered de/data/skater/nico-ihle. The plugin shows me, that my custom rule is beeing selected:

(de|en)/data/skater/(.*?)?/?$ 	

        page_id: 814
         skater: nico-ihle
           lang: de

In other words, WPML and Rewrite analyzer are working as expected, but PL not. I hope that the given information can help you to give me a support or to identify the problem behind.

Please can you check this and provide a fix or sollution?

Thank you and regards,

Hi,

well it is pretty simple. I send you here the full code so that you can reproduce the problem

add_filter('query_vars', 'myvar_vars');
	function myvar_vars($public_query_vars) {
		$public_query_vars[] = 'skater';
		return $public_query_vars;
	}

	add_action('generate_rewrite_rules', 'myvar_add_rewrite_rules');
	function myvar_add_rewrite_rules($wp_rewrite) {

		$new_rules = array(
			'(de|en)/data/skater/(.*?)?/?$' => 'index.php?page_id=814&skater='.$wp_rewrite->preg_index(2).'&lang='.$wp_rewrite->preg_index(1),

			'(data/skater)/(.*?)?/?$' => 'index.php?pagename='.$wp_rewrite->preg_index(1).'&skater='.$wp_rewrite->preg_index(2),
			'(de|en)/(data/skater)/(.*?)?/?$' => 'index.php?pagename='.$wp_rewrite->preg_index(2).'&skater='.$wp_rewrite->preg_index(3).'&lang='.$wp_rewrite->preg_index(1),
		);

		$wp_rewrite->rules =  $new_rules + $wp_rewrite->rules;
	}

	add_action( 'template_redirect', 'change_search_url_rewrite' );
	function change_search_url_rewrite() {
			global $wp_query, $wp, $db;
			error_log(print_r($wp,true));
	}

Well, this is the code, I’m using to test. The “only” problem is, that when I activate Polylang, my rules are not fire (but they are firing with WPML or rule analyzer etc.).

For me it seems so, that when activating PL it does anything with the rewrite rules, so that they are not working anymore. In fact “skater” is not set, because the wrong rule is taken. One of the real strange things is, that the rule analyzer is working as expected in the WP-Admin.

Du you have an idea? It is really important to me, because PL seems to be must more performant then WPML and I really would like to switch. But therefore it has to work before 😉

Lars
