SEO links in header

Yes. Let me know if this works for you:

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!

Yes, you can use substr( $blog->get_language(), 0, 2 ) in this case.

Please read on here: https://github.com/lloc/Multisite-Language-Switcher/wiki/Change-the-output

Got that.

Any idea about the individual urls?

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' );

Resolved

OK, excellent. I added some code here.

Could tell something about the alternative links?

Thanks for cleaning up ??

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

Very good! Thanks for pointing that out.

Please, would you like to consider adding this feature into the plugin?

hreflang attribute is of great value in this kind of setup.

Vielen Dank für das Plugin!

Gern geschehen!

Yes, this feature will probably added to the plugin in the near future: https://github.com/lloc/Multisite-Language-Switcher/issues/45
