linking paged archiv pages

[timholz]

Hi - using msls, i noticed that for paged categories or tags, i am pointed to the start of the category/tag.
example:
http://localhost/kategorie/archiv/seite/2/
points to:
http://localhost/es/categoria/archivo/
expected link should be:
http://localhost/es/categoria/archivo/pagina/2/

Notice, i changed the default wordpress url-term «page» to /seite/ - /pagina/, using a rewrite rule.

I replicated the plugin and for example for archive pages i use:

// is_ES() is a function that checks get_locale()
 if (is_ES() == true){
        $page = 'seite';
        $myblog_id = 1;
    } else {
        $page = 'pagina';
        $myblog_id = 2;
    }

if (is_archive()){
        $cat_base = get_option('category_base');
        switch_to_blog($myblog_id );
        //since get_category_link doesn’t work
        //properly, (it prints the category base of the
        //opposite blog) i’ve taken a different
        //approach with str_replace()
        //see: https://core.trac.wordpress.org/ticket/48786
        $cat_dest = get_option('category_base');   
        $url_cat = get_category_link(get_query_var( 'cat' ));
        //check if it’s paged
        if (get_query_var( 'paged' ) > 0){
            //adding $page and the number to the url
            $cat_switch = str_replace($cat_base, $cat_dest, $url_cat) .$page.'/'.get_query_var( 'paged' ).'/';
        } else {
            $cat_switch = str_replace($cat_base, $cat_dest, $url_cat);
        }
        restore_current_blog();
    }

This bears the desired link:
http://localhost/kategorie/archiv/seite/2/
points to:
http://localhost/es/categoria/archivo/pagina/2/

Another incongruence arises, if a developper shows similar posts with pagination in single.php.
To avoid this i suggest something like:

if (is_ES() == true){
        $href = get_site_url(1);
        $myblog_id = 1;
        $key = 'de_DE';
        $page = 'seite';
    } else {
        $href = get_site_url(2);
        $myblog_id = 2;
        $key = 'es_ES';
        $page = 'pagina';
    }

if (is_single() || is_page() && !is_front_page()) {
        //get the tied option
        $getopt = get_option('tim_post_'. get_the_ID() );
        if (isset($getopt[$key]) && get_query_var('paged') == 0 ){
            $post_switch = get_blog_permalink( $myblog_id, $getopt[$key] );
        } else if (isset($getopt[$key]) && get_query_var('paged') > 0 ){ 
            $post_switch = get_blog_permalink( $myblog_id, $getopt[$key] ) .$page.'/'.get_query_var( 'paged' ).'/';
        } else {
            $post_switch = $href;
        }
    }

How about providing the fitting links for paged archives and paged similar posts in single.php?
