Как сделать комментарий спойлером, если рейтинг минусовой?

if($row['rating'] > 0 ) {
	$tpl->set( '[positive-comment]', "" );
	$tpl->set( '[/positive-comment]', "" );
	$tpl->set_block( "'\\[negative-comment\\](.*?)\\[/negative-comment\\]'si", "" );
	$tpl->set_block( "'\\[neutral-comment\\](.*?)\\[/neutral-comment\\]'si", "" );
} elseif($row['rating'] < 0){
	$tpl->set( '[negative-comment]', "" );
	$tpl->set( '[/negative-comment]', "" );
	$tpl->set_block( "'\\[positive-comment\\](.*?)\\[/positive-comment\\]'si", "" );
	$tpl->set_block( "'\\[neutral-comment\\](.*?)\\[/neutral-comment\\]'si", "" );	
} else {
	$tpl->set( '[neutral-comment]', "" );
	$tpl->set( '[/neutral-comment]', "" );
	$tpl->set_block( "'\\[positive-comment\\](.*?)\\[/positive-comment\\]'si", "" );
	$tpl->set_block( "'\\[negative-comment\\](.*?)\\[/negative-comment\\]'si", "" );
}
