How to maintain separate permalink structure for specific category posts in wordpress

Hi Currently in our wordpress our default permalink structure is

abc.com/%postname%-%post_id%.html

But for specific category I want different permalink structure
Ex: for Photos Category i want url structure as

abc.com/%post_id%.html

Current i am using the following code But it is not working

add_filter( 'post_link', 'custom_permalink', 10, 3 );
function custom_permalink( $permalink, $post, $leavename ) {
    // Get the categories for the post
    $category = get_the_category($post->ID); 
    if (  !empty($category) && $category[0]->cat_name == "Photos" ) {
        $permalink = trailingslashit( home_url('/'.$post->ID .'.html' ) );
    }
    return $permalink;
}

But i am not getting different permalink structure for specific category posts. Please help me.
