[Resolved] Href lang tags

The screenshot you send me from heatperformance.ch was a screenshot of the homepage. Only the category pages are showing the wrong rss feed.

So:
The category pages on .ch and .de -> shows .at rss feed
The category pages on .be -> shows .nl rss feed

Hello Christopher,

Thanks for building this installation. There is no canonical - not only on the category page as well as on the product pages.
I can't find out why they don't appear.

On the category page "hidden link" I filled out the field Canonical URL manually.

But still the canonical does not appear in the source code.

There must be somewhere some setting I think. But I can't find it either.

Best regards,
Lobke

Hi Long,

Thanks for your reply.

I have actually 2 code snippets on my website. The first one:

/**
* Forceer een canonical-URL op WooCommerce productcategorieën
* als Yoast er zelf geen uitspuugt.
*/
function hp_fix_yoast_canonical_for_product_cat( $canonical ) {
// Alleen ingrijpen als er nog géén canonical is
if ( ! empty( $canonical ) ) {
return $canonical;
}

// Alleen voor WooCommerce productcategorie-archieven
if ( function_exists( 'is_product_category' ) && is_product_category() ) {
$term = get_queried_object();

if ( $term && ! is_wp_error( $term ) ) {
$url = get_term_link( $term );

if ( ! is_wp_error( $url ) ) {
$canonical = $url;
}
}
}

return $canonical;
}
add_filter( 'wpseo_canonical', 'hp_fix_yoast_canonical_for_product_cat', 10, 1 );

And a second one, as on sites which share the same language, a wrong canonical was shown. For example on our .be website .nl canonicals were shown. This is the second code snippet:

/**
* Forceer Yoast canonical naar de huidige URL (self-referencing).
* Nodig bij multidomain setups als Yoast/WPML verkeerde canonicals uitsturen.
*/
add_filter( 'wpseo_canonical', function( $canonical ) {

if ( is_admin() ) {
return $canonical;
}

$host = $_SERVER['HTTP_HOST'] ?? '';
if ( empty( $host ) ) {
return $canonical;
}

$scheme = is_ssl() ? 'hidden link' : 'hidden link';
$uri = $_SERVER['REQUEST_URI'] ?? '';
$current = $scheme . $host . $uri;

// Geen querystrings in canonical
$current = strtok( $current, '?' );

return esc_url( $current );
}, 20 );

Unfortunately I don't have a test environment. I used to have it, but it was useless because a lot of plugins (WPML as well) did not function.

Why don't we enable the this for a moment: "Discourage search engines from indexing this site" on the Settings > Reading page by default to prevent indexing content, so the canonical won't be created by Yoast.

And then check of the canonicals are shown on the category pages of the sandbox environment.

Best regards,
Lobke
