Problem:
The client is unable to translate a PDF file assigned to a custom 'project' post using an ACF field of type 'file'. The field is set to 'Translate' in WPML settings, but it does not appear in the translation screen, and the same PDF file as the PL version is automatically used for the EN version.
Solution:
We recommended inserting the following code into the theme's functions.php file to allow translating numeric values, which include the PDF file ID:

function wpmlsupp_7499_allow_translating_numbers( $is_translatable, $job_translate ) {
    $data = $job_translate['field_data'];
    
    if ( 'base64' === $job_translate['field_format'] ) {
        $data = base64_decode( $data );
    }
    
    if ( is_numeric( $data ) ) {
        return true;
    }
    
    return $is_translatable;
}
add_filter( 'wpml_tm_job_field_is_translatable', 'wpmlsupp_7499_allow_translating_numbers', 10, 2 );

After adding this code, make a minor change to the page title and attempt to translate the PDF file ID, which should now be visible in the media library. Additionally, we suggested using the Media Translation interface for a more user-friendly approach to translating the PDF file.
