Question [Solved] Reply comments

@jon62,

Use the hook code below: 

add_filter('wpdiscuz_comment_list_args',function($args){
    $current_user = wp_get_current_user();
    $current_user_roles = (array)$current_user->roles;
    if($args['can_user_reply'] && !in_array('administrator', $current_user_roles)){
        if(!in_array('role_name', $current_user_roles)){
            $args['can_user_reply'] = false;
        }
    }
    return $args;
});
add_filter('preprocess_comment', function($commentdata){
    $current_user = wp_get_current_user();
    $current_user_roles = (array)$current_user->roles;
    if($commentdata['comment_parent'] && !in_array('administrator', $current_user_roles)){
        if(!in_array('role_name', $current_user_roles)){
            wp_die('You don\'t have permission to comment.');
        }
    }
    return $commentdata;
});

For administrators, the code works fine. 

You should change the red marked value for the particular user role who should be able to reply.
