Error about headers being not set

hi,

setting up cookies is giving me an error about headers being not set.

all the trailing spaces i have removed in my small code.

let me know if there is any configuration left to do.

thanks for your kind reply.
but this is not helping me.. if you check out the file ive attached, you'll see that i have fulfilled the requirements regarding the spaces and prioritiesm but the error still persists.

Here is the error:

Warning: Cannot modify header information - headers already sent by (output started at C:\wamp\www\login.php:5) in C:\wamp\www\login.php on line 6

The same code works on different machines.

Did you read the fourth post in that thread?

Anyway, your code is

PHP Code:


<head>
<title>Processing...</title>
</head>
<body>
<?php
setcookie('test',45,time()+(60*60));
?>
</body>
</html>

That is the same as

PHP Code:


<?php
echo "<head>\n<title>Processing...</title>\n</head>\n<body>\n";
setcookie('test',45,time()+(60*60));
echo "</body>\n</html>";
?>

The problem is that when you use echo or straight HTML, you are implicitly sending the headers, which you can't do before the setcookie() function.

Use this code:

PHP Code:


<?php setcookie('test', 45, time() + 3600); ?>
<html>
<head>
<title>Cookie Processed</title>
</head>
<body>

</body>
</html>

or this code

PHP Code:


<?php ob_start(); ?>
<html>
<head>
<title>Cookie Processed</title>
</head>
<body>
<?php setcookie('test', '45', time() + 3600); ?>
</body>
</html>
<?php ob_end_flush(); ?>

Thankyou.. This works!!

I took lessons from Lynda's training videos. My script matched the guy's script. At first attempt my script worked fine. but due to system failure, i had to format my pc only to find that this script isn't working anymore.

I did read the 4th post in the thread, but due to what i learned, i was unable to find the difference.

Anyways,
Thanks for your kind help.
