[Resolved] Function that adds a class to the body tag of each page based on the page slug is not working in tra...

Problem:
The function intended to add a page slug as a class to the body tag does not work on WPML translated versions of the site, causing issues with page-specific styling.
Solution:
To ensure the function works with WPML translated versions, you need to modify the function to use WPML's hooks for managing translations. Here is a step-by-step guide:

function add_slug_body_class_wpml_fallback( $classes ) {
$original_id = get_queried_object_id();

// Check if WPML is available
if ( class_exists( 'sitepress' ) ) {
$current_lang = apply_filters( 'wpml_current_language', null );
$translated_id = wpml_object_id( $original_id, 'page', true, $current_lang );
} else {
$translated_id = $original_id;
}

// WPML logic continues
if ( $translated_id ) {
$post_type = get_post_type( $translated_id );
$post_slug = get_post_field( 'post_name', $translated_id );

if ( $post_type && $post_slug ) {
$classes[] = $post_type . '-' . $post_slug;
}
}

return $classes;
}
add_filter( 'body_class', 'add_slug_body_class_wpml_fallback' );

Before implementing this solution, ensure to back up your site and have FTP access ready as a precaution. This modification involves developer-level changes, which are usually beyond standard support scope. For more details on WPML's hooks, visit WPML Hooks Reference.
