Zodra ik een code invul dan blijft hij onjuist zeggen terwijl ik wel de goede code invul.

Wie kan me helpen.

Mvg,

Ik neem aan dat de code 1 is?

toevoeging op 24 mei 2013, 19:33:52:
if($_POST[code] == ) {

kun je beter vervangen door:

if(empty($_POST[code])) {

Je kan beter gewoon trim() doen. Dus if(trim($_POST[code]) == )

Vanwaar die exit() nergens voor nodig. je script moet niet stoppen, hij moet gewoon een deel code overslaan.
