cookie problem

[p80]

what's wrong with this script


$uploaddir = 'postimages/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

echo '<pre>';
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
echo "File is valid, and was successfully uploaded.\n";
echo "Createing refrence file...\n";
$fileName = $_FILES['userfile']['name'];
setcookie('myImage', $fileName, time()+864000);
} else {
echo "File upload failed\n";
}


print_r($_FILES);

print "</pre>";


the error I get

Warning: Cannot modify header information - headers already sent by (output started at /home/partical/public_html/imgUpload.php:8) in /home/partical/public_html/imgUpload.php on line 13

line 13 is the cookie. the upload works fine, but I'm brain farting on the cookie. thanks

It is an error to send header information after any output. Cookies are header information, so setting one after you do an echo is an error. It can still work as long as output buffering is in place, but it's better to avoid relying on it and set cookies before any output is sent.
