get_permalink after switch_to_blog function

  • Hey guys!

    We have multisite, that is handles different languages of same site (mainsite.com, mainsite.com/it – for italian version, mainsite.com/de for germany, etc)
    We have custom post types on the site (for example “books”) with TRANSLATED url rewrite slug (like mainsite.com/books/book1, mainsite.com/it/libri/prenota1, mainsite.com/de/bucher/buch1) – we add translated slug when register_post_type is launched . Also we store connection between these posts in the database (so they linked).
    For such posts we want to show, that they have translated versions.

    We was trying to use native WP multisite functional like switch_to_blog() and get_permalink() functions, but unfortunately we’ve stacked, as get_permalink() returns link using CURRENT rewrite slug
    It shows mainsite.com/it/books/prenota1, mainsite.com/de/books/buch1
    when you’re on the main site and mainsite.com/libri/book, mainsite.com/de/libri/buch1
    when you’re on Italian version.

    Is it correct that after switch_to_blog() function permalink structure remains the same? because in such situation using native WP functional is not really useful ??

  • You don’t say the order of execution of your code, but switch_to_blog will switch out the object cache, so the variables you are working with for the query should be switched. I didn’t follow the code all the way down to see if the query is done again on the other blog, but it doesn’t seem like it would be since it is a separate blog.
    The point is that get_permalink uses the post passed or the global post, so you have to check the code to see if you need to repeat the query on the switched blog to get the post on that one. Or just use a filter to compute the permalink for the other sites, based on the current one.

    Hey Joy! Thanks for the response.
    Main thing, I’m getting correct page, except this wrong untraslated rewrite slug. I can show this part (will remove additional checks for better reading)

      
foreach( $language_blogs as $blog_id => $language_id ) {
            if (!array_key_exists($blog_id, $linked_pages))
                continue;

            switch_to_blog($blog_id);

            $post_id = $linked_pages[$blog_id];
            $url = get_permalink($post_id);
            $links[$language_id] = $url;

            restore_current_blog();
}

    As you can see, I pass correct post ID to the get_permalink function. But it is being built using permalink structure from CURRENT blog, and not the switched one.
    So don’t understand if I’m doing something wrong?

    That is exactly what I said last time. The switch_to_blog swaps the global variables (like the object cache which is what is retrieved from the query), but if you didn’t retrieve anything from the other blog, you can’t expect it to work. You would have to do a new query on the other blog. They are separate.

    Thanks, I understand that they are separate. I don’t understand how I can get URL of the linked page by post ID from another blog using another blog permalink structure.
    What should I query first?

    If you have the correct post ID for the other blog, I think you could do a get_post(). If you don’t have the correct ID, you need to do whatever query you need to get it.
    Be sure to switch back when you are done.

    Aloha, just chiming in here since I discovered this bug as well. It is an actual bug (sorry @joyously), but was reported in Trac in 2012 and closed as wontfix (due to being difficult and not performant to fix):
