Orio Posted April 25, 2006 Share Posted April 25, 2006 You somewhere sent something to the browser, you wrote something. It could be a <html> tag at the top of the page, or just a white space you have by mistake. Put the seession_start() at the very top of the page.Orio.

zxiny_chin Posted April 25, 2006 Author Share Posted April 25, 2006 you mean put session start before <?php ? Link to comment https://forums.phpfreaks.com/topic/8354-need-help-with-session_start/#findComment-30491 Share on other sites More sharing options...
Orio Posted April 25, 2006 Share Posted April 25, 2006 No, I mean:[code]<?php session_start(); ?>...all the rest here....[/code]But if you need to do something before you call the session_start(), make sure nothing is being echo'd or normaly written with html. Once I went nuts because one of my included files had a white space after the ending "?>" and I got the same error when I tried to send a cookie.Orio.

Orio Posted April 25, 2006 Share Posted April 25, 2006 This is your problem:[code]the main page<body><?phpsession_start();....[/code]You see, you need to delete the <body> tag. You cant have anything sent to the browser (to be written in the source code as html) before setting a cookie, a session, or using the header() function (Maybe there are more stuff that I dont know).Do something like this:[code]<?phpsession_start(); echo("<body>");....Rest of code....[/code]Orio.

kenrbnsn Posted April 25, 2006 Share Posted April 25, 2006 You don't have to delete the "<body>" tag, just put[code]<?php session_start() ?>[/code] at the very start of the file.Ken Link to comment https://forums.phpfreaks.com/topic/8354-need-help-with-session_start/#findComment-30537 Share on other sites More sharing options...
