Re: [PROGRAMMERING] <form action="<?php echo $PHP_SELF?>" method="POST">

Så vidt jeg kan læse, ud fra det du skriver, vil det kræve at REGISTER GLOBALS er slået til i PHP før du kan gøre som du ønsker. REGISTER GLOBALS gør det, at den søger efter variabler med post, get og cookie-metoderne. Finder den disse variabler, tildeler den værdierne af dem, til deres navn.

Det er korrekt. Og register_globals har været slået fra i standardopsætningen af PHP i ganske lang tid nu. Det er der en grund til, så derfor bør man ikke slå den til med mindre man ved, hvad man gør, og hvad konsekvenserne er.


Det er generelt smartest at fange værdier fra formularer med de specielle variable i stedet. De hedder $_POST, $_GET og $_COOKIE, og deres indhold er også samlet i den fælles $_REQUEST.

I stedet for at smide $_POST['submit'] over i en anden variabel og teste på den, kan man gøre således:

if(isset($_POST['submit']))

eller bare

if($_POST['submit'])

men den anden metode vil give en NOTICE, hvis man har slået det til.

Med venlig hilsen

Ole
