Ovo bi trebalo da radi.
Tebi je submit form ocigledno u drugoj stranici.
$_POST je array i sa funkcijom isset() proveravas dali se elemant nalazi unutra pre nego sto ga koristis u suprotnom mozes da dobijed gresku da taj index ne postoji u nizu.
Takodje treba da setujes inicijalne vrednosti za proenjive koje ces koristiti.
Ti bi trebao da otvoris form stranicu uneses podatke i da te submin trebaci na ovu, a ne da ovu otvaras direktno.
Dopuna: 18 Avg 2012 9:13
Notice: Undefined variable: tireqty in C:\xampp\htdocs\bob1.php on line 23
ovo znaci da oces da koristis (ehujes) promenjivu koja nije nigde definisana posto kod nije usao unutar if-a
