Help creating this argument

[shuban]

I want to create an argument like the one below, but I don't know what to put for IS A REPLY. So, if the subject is less than 10 characters and is not an administrator and it's a brand new topic (or has no replies)...

Code: [Select]

if($func['strlen']($_REQUEST['subject']) <= 10 && !$user_info['is_admin'] && IS A REPLY)
$post_errors[] = 'bad_short_title';
This is going into Post.php.
