[Closed] remove outgoing hreflang annotation from some URL (noindex URLS)

Hi There!
Thanks for contacting WPML Support.

I understand what you're looking for. If you want a specific tag or taxonomy with a `noindex` directive to not have the hreflang tag, it is possible to achieve that using the `wpml_hreflangs_html` filter hook with a callback function to remove the hreflang. For example, check the code below, which might help remove the hreflang if the tag or taxonomy has the `noindex` directive.

add_filter( 'wpml_hreflangs_html', function( $hreflang ) {
    // Check if the current page is a taxonomy page (tag, category, or other taxonomy)
    if ( is_tag() || is_category() || is_tax() ) {
        // Get the robots meta using the wp_robots filter and check if 'noindex' is set
        $robots_meta = apply_filters( 'wp_robots', [], get_queried_object() );
        // Check if 'noindex' is in the robots meta array
        if ( is_array( $robots_meta ) && in_array( 'noindex', $robots_meta ) ) {
            // If 'noindex' is found, prevent the hreflang tags from being output
            $hreflang = '';
        }
    }

    return $hreflang;
} );

I hope the above code helps you understand the process. However, I’d like to inform you that providing custom coding support is beyond the scope of our support. The code solution above is for demonstration purposes and may assist in solving the issue. If you require further coding assistance, you may need to hire a professional developer experienced in customizing WPML. You can find one here: https://wpml.org/contractors/.

I hope you can understand. Feel free to let me know if you have any other questions or need clarification. I'll be happy to help.

Best regards,
Prosenjit
