พี่ๆช่วยดูให้หน่อยนะครับคือว่าผมต้องการลบไฟล์ทีอัพโหลดออกด้วยนะครับ

     if (($strID!="") && ($strID!="0"))
	{
		$strsql="DELETE FROM news_t_newsdetails ";
		$strsql.= " WHERE id=" .SQLSafeString($strID);
		$var1=$conclass->Execute ($strsql,$strErrorMessages);
		if ($strErrorMessages!="")
		{
			$strErrorMessages = "Could not delete the news information. " .$strErrorMessages;
		}else
              unlink("direct_path/file_name"); // คำสั่งลบไฟล์
         }
	}
