Problem: The client wants to add a custom hreflang tag for Canadian English (en-ca) that points to the existing US English (en-us) content without creating a new language in WPML.
Solution: We recommend using a filter to modify the hreflang links before they are added to the page head. The filter 'wpml_hreflangs' can be used to add an associative array of language codes and URLs. Here's the code to add to the child theme's functions.php file or a custom plugin:
/**
* Add an hreflang link for en-ca pointing to the en-us URL
*/
add_filter( 'wpml_hreflangs', 'wpmlsupp_mod_hreflangs' );
function wpmlsupp_mod_hreflangs( $hreflang_items ){
if ( is_array($hreflang_items) && isset($hreflang_items['en-us']) ){
$hreflang_items['en-ca'] = $hreflang_items['en-us'];
}
return $hreflang_items;
}
