Alstublieft

Waarom verander je En je sluit de php regel niet af.
En je vergeet de echo..

Als je helpt, help dan wel goed?

Die had ik niet gezien..

Bedankt jongens, Heb nu even een vraagje geen zin om er een heel topic voor aan te maken.

Als je 2 forms hebt en dus 2 verschillende submit knoppen, 1tje voor bijvoorbeeld wachtwoord veranderen en 1 voor email veranderen. Als je wachwoord veranderd moet worden heb je dit script:

if($_POST[wachtwoord]){mysql_query("UPDATE gebruikers set wachtwoord= ".mysql_real_escape_string(sha1($_POST[wachtwoord]))." WHERE id= " . mysql_real_escape_string($_SESSION[gebruiker]) . "");}

En voor mail deze

mysql_query("UPDATE gebruikers SET   
                email = ".mysql_real_escape_string($_POST[email])."   
                WHERE id = ".$_SESSION[gebruiker]);   
                // Vervolgens moet de pagina vernieuwd worden.   
                header(Location: .$_SERVER[REQUEST_URI]);

Hij voert ze allebei uit als je op submit klikt hoe verander je dat.

Hij voert ze allebei uit als je op submit klikt hoe verander je dat.

Wat moet je veranderen als hij het doet?

Maar 1 van de 2 moet worden uitgevoerd.

Waarom krijg ik alle fotos te zien en alle texten? Het is de bedoeling dat die random weergeeft.
