interpim Posted January 23, 2008 Share Posted January 23, 2008 change it and take out everything except your php code... put your setcookie() on the very first line of code Link to comment https://forums.phpfreaks.com/topic/87294-cookie-problem/#findComment-446499 Share on other sites More sharing options...
nvidia Posted January 23, 2008 Author Share Posted January 23, 2008 Hi thanks for your quick response. I have removed everything even the html code to be left with: <?php setcookie('test', 45, time()+(60*60*24*7));?> but i still get the message of Warning: Cannot modify header information - headers already sent by (output started at C:\wamp\www\php_sandbox\cookies.php: 3) in C:\wamp\www\php_sandbox\cookies.php on line 3. Even with the HTML code, it should work right?? Link to comment https://forums.phpfreaks.com/topic/87294-cookie-problem/#findComment-446502 Share on other sites More sharing options...
interpim Posted January 23, 2008 Share Posted January 23, 2008 are you calling this script from another page? Link to comment https://forums.phpfreaks.com/topic/87294-cookie-problem/#findComment-446507 Share on other sites More sharing options...
jambroo Posted January 23, 2008 Share Posted January 23, 2008 Try this from http://au2.php.net/manual/en/function.setcookie.php: <? header("Content-Type: text/html; charset=utf-8"); setcookie("aaa", "bbb"); ?> <html> <head> ...

interpim Posted January 23, 2008 Share Posted January 23, 2008 well... the problem is when you use setcookie() it sends a header, so if you are calling it from another script that writes anything else to the screen then it will give that error unless you use output buffering... That script by itself shouldn't give that error, but if you are calling it from another script that you expect output from you will get that error... output buffering can be turned on in the script you call your setcookie from by putting ob_start(); at the beginning of the script and then an ob_end_flush(); at the end. But there are some disadvantages to this primarily concerning security...

hamza Posted January 24, 2008 Share Posted January 24, 2008 good PIECE OF ADVICES as MY FRINED SAID PLACE YOUR COOKIE ON FIRST LINE. AND ABOUT BUFFER YOU CAN SET THE BUFFER IN TWO WAYS FROM PHP.INI FILE OR YOU CAN USE THE START_OB(); OR GO TO PHP.NET FOR MORE BUFFER INFORMATION IF STILL YOU HAVE ANY PROBLEM THEN SEND ME YOU ALL CODE OR ONE THING MORE PLACE YOUR COOKIE IN YOUR HEADER NOT IN YOUR BODY Link to comment https://forums.phpfreaks.com/topic/87294-cookie-problem/#findComment-447639 Share on other sites More sharing options...
