A while back a potential customer asked me, if it is possible to restructure a WordPress Multisite setup and WPML with a more simplified and custom url structure?
web.site/de/
web.site/en/
Languages would normally be added like this:
web.site/nl-nl/de/
web.site/nl-nl/en/
The customer wanted it to be restructured / simplified like this:
web.site/de-nl/
web.site/en-nl/
This basically mimics the structure of a single WPML website with custom languages, but with all the benefits of a multisite.
This is nothing that WPML or WordPress Multisite provides out of the box.
I built a prototype setup to make it work.
Not something that I would propose for anyone, as it requires a lot of tweaks for anything that handles dynamic links (plugins, hooks, core systems, page.builder …)
Its doable :)
One thing that needs to be tweaked globally, is the mapping of the new url structure.
So web.site/nl-nl/en/ needs to become web.site/en-nl/
This needs to be handled on the server side, by proxying the original to the new structure.
This can be easily done using Apache or NGINX.
With that web.site/nl-nl/en/ will be proxied to web.site/en-nl/, but any core navigation will not work yet.
This is the fastest solution that I came up with, within the hour I gave myself ;)
There surely are other options, like the core rewrites / restructuring of the core shorturl handling. But these approaches might break things in far more areas.
Using the proxy approach, keeps the core as it is. The solution needs to be as simple as possible, allowing to maintain it in the future :)
Just for the basic setup a couple of hooks are required to make this work, more might be needed depending on the plugins in use.
Here a couple of examples ….
WordPress site_url
|
1 2 3 4 5 6 7 8 9 |
add_filter( 'site_url', 'custom_site_url' ); function custom_site_url( $url ) { if( is_admin() ) // you probably don't want this in admin side return $url; return str_replace( "/nl-nl/en/","/en-nl/", $url); } |
WordPress Nav Links
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
add_filter( 'post_link', 'changePermalinks', 10, 3); add_filter( 'page_link', 'changePermalinks', 10, 3); add_filter( 'post_type_link', 'changePermalinks', 10, 3); add_filter( 'category_link', 'changePermalinks', 11, 3); add_filter( 'tag_link', 'changePermalinks', 10, 3); add_filter( 'author_link', 'changePermalinks', 11, 3); add_filter( 'day_link', 'changePermalinks', 11, 3); add_filter( 'month_link','changePermalinks', 11, 3); add_filter( 'year_link', 'changePermalinks', 11, 3); function changePermalinks( $url, $post, $leavename=false ) { $url = str_replace("/nl-nl/en/","/en-nl/", $url); return $url; } |
WPML
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
add_filter( 'icl_ls_languages', 'wpml_url_fix'); function wpml_url_fix( $languages ) { global $wpml_url_converter; $abs_home = $wpml_url_converter->get_abs_home(); foreach( $languages as $lang => $element ){ $languages[$lang]['url'] = str_replace( "/nl-nl/en/","/en-nl/", $languages[$lang]['url'] ); } return $languages; } |
Rankmath
|
1 2 3 |
add_filter( 'rank_math/frontend/canonical', function( $canonical ) { return str_replace( "/nl-nl/en/","/en-nl/", $canonical); }); |
This will not cover every angle, but will give you a starting point! I love my puzzles and there always is a viable solution :)
