isset() function එකෙන් පුලුවන් variable එකක් set වෙලාද (එහෙම variable එකක් තියෙනවද) කියල බලන්න. $_POST["login"] කියන variable එක (submit button එකෙන් හැදෙන variable එක) හැදෙන්නෙ form එක submit කරල නං විතරයි.

if (!isset($_POST["login"]) || ($_POST["login"] != "Login"))

මේ පේලියෙන් චෙක් කරන්නෙ ඒක. $_POST["login"] කියන variable එක නැත්තං හෝ $_POST["login"] කියන variable එකේ value එක "Login" නොවේ නං (ඒ කියන්නෙ form එක submit කරල නැත්තං) form එක පෙන්නන්න කියල.

Submit කලාම කොහොමත් Page එක Refresh වෙනවා. එහෙම නොවෙන්න නම් Ajax වගේ එකක් Use කරන්න වේ. උබ Submit එක Click කරම form එකේ තියන Action එකට දාල තියන .php File eka Execute වෙනවා. එච්චරයි.
