die Zeile
header("Location: help_de.html");
ist der entscheidende Ansatz. Sobald der Fall eintritt, wo er auf diese Seite wechseln soll, kommt nur die Fehlermeldung
Who is online?
Warning: Cannot add header information - headers already sent by (output started at c:\foxserv\www\chat\html\mainonlinelist.php:49) in c:\foxserv\www\chat\html\mainonlinelist.php on line 113
woran liegt das und was kann man da machen?
danke für eure hilfe!

Hi,
ich poste gleich mal etwas quellcode:
beschränke es bitte auch auf "etwas". Ein komplettes Script muss nun wirklich nicht sein.
Warning: Cannot add header information - headers already sent
woran liegt dasWas daran verstehst Du nicht?
und was kann man da machen?
Der HTTP-Header ist beendet, sowie das erste Byte des HTTP-Bodies geschrieben wird. Also: Sende die Header _vor_ dem Body.
Siehe auch Archiv.

hi
du kannst den header nur senden, wenn du noch KEIN!!! einziges zeichen an den browser ausgegeben hast. du kannst also beliebig viel php-code basteln, aber kei print, bzw. echo machen! sobald du 1 zeichen an den browser ausgegeben hast, ist es vorbei...
