Passaggio da php4 a php5, non funziona lo script

12-11-2009, 17.50.00

Salve ho un problema su uno script php che funziona perfettamente sul supporto php4, ma non funziona sul php5.
Siccome avrei necessità di trasferire lo script sul php5, ve lo posto per vedere se qualcuno saprebbe dirmi dove devo aggiornare...
si tratta di un form per sondaggi con pagina di amministrazione.

pagina admin.php con password di accesso

Codice PHP:


<?php





$password="admin";





//#########################################################

if(!isset($passwd) or $passwd!=$password){

echo "<table width=\"303\" border=\"0\" cellspacing=\"1\" cellpadding=\"0\" height=\"169\" bgcolor=\"#336699\" align=\"center\"><tr><td bgcolor=\"#336699\" height=\"110\">

Ricevi qualche errore?
Register Globals è attivato o disattivato?

12-11-2009, 18.36.03

non ricevo errori, solo che quando clicco "invia" non fà nessuna azione.
Il register globals è attivato, ho provato a disattivarlo ma è uguale
