Thanks for cleaning up 😃

The hreflang alternate tags are for SEO purposes. Making Google and others understand the structure of the multilingual content.

Ok, got this to work, thanks for your help!

function my_print_something() {
    foreach ( MslsBlogCollection::instance()->get() as $blog ) {
	$lang = $blog->get_language();
	$mydata = MslsOptions::create();
	switch_to_blog( $blog->userblog_id );
        printf(
            '<link rel="alternate" hreflang="%1$s" href="%2$s" />',
            substr( $blog->get_language(), 0, 2 ),
			$mydata->get_permalink($lang)
        );
		restore_current_blog();
    }
}
add_action( 'wp_head', 'my_print_something' );

Not quite, but it’s a start.

You missed a , in the printf.

Languagecode are full like en_GB, but i just need en (which i can strip in the code I guess)

I need full urls to the blog and translations including current language.
So different for each blog item or page.

Thanks so far!
