Setting Basic Cookies

Anon

I've been trying to do a simple cookie demo, just to see how they work using the following script:

<?
if (!isset($localcook)) {
if (!$name) {
?>
<form method="post" action="<? print $PHP_SELF; ?>">
Name:<input type="text" name="name"><br>
<input type="hidden" name="task" value="set">
<input type="submit" value="Set that cookie!">
</form>
<?
} else {
setcookie("localcook",$name,time()+3600,"/");
header("location: $PHP_SELF");
}
} else {
print "Name: ".$localcook;
}
?>

But it returns:

Warning: Cannot add header information - headers already sent by (output started at c:\apache\htdocs/dev/cookie.php:9) in c:\apache\htdocs/dev/cookie.php on line 20

Warning: Cannot add header information - headers already sent by (output started at c:\apache\htdocs/dev/cookie.php:9) in c:\apache\htdocs/dev/cookie.php on line 21

Can anyone give me a hand with this?

you must have the header information sent as the very first thing in the file. that means no spaces, line breaks, etc...

This code worked for me:

<?
if(!isset($localcook)) {
if ($name) {
setcookie("localcook",$name,time()+3600,"/");
header("location: $PHP_SELF");
}
else {?>
<form method="post" action="<?print $PHP_SELF;?>">
Name:<input type="text" name="name"><br>
<input type="hidden" name="task" value="set">
<input type="submit" value="Set that cookie!">
</form>
<? }
}
else {
print "Name: ".$localcook;
}
?>

I kinda changed it around a little bit but nothing big. Hope it helps!

Hi,

the header function can only be used before any other text is printed,
(Even before the <?)

Heh.

Yeah, the script DOES work, but it being a lazy friday afternoon, my brain failed to register that it wouldn't work on my local workstation.

D'oh.
