Soemthing like this should work...

cookies.php

code:

<?





if ($UsrCookie) {

	echo("Welcome $UsrCookie, change your user name below");

}else{

	echo("You do not have a User Name (or are not accepting cookies) enter a user name below:");

}



?>



<form action="sendcookie.php">

<input type="text" name="usrName" size="20" maxlength="20">

<input type="submit" name="Submit" value="Submit">

</form>

sendcookies.php

code:

<?



setcookie("UsrCookie",$usrName,time()+86400);



header("Location: cookies.php");



?>

what kind of problems are you having? maybe we could clarify why you are having those problems...

Actually, you can set & read cookies on the same page, but you have to reload page after setting them. Here's one example from PHP's web site:

<?php
$status = 0;
if (isset($myTstCky) && ($myTstCky == "ChocChip")) $status = 1;
if (!isset($CCHK)) {
setcookie("myTstCky", "ChocChip");
header("Location: $PHP_SELF?CCHK=1");
exit;
}
?>
<html>
<head><title>Cookie Check</title></head>
<body bgcolor="#FFFFFF" text="#000000">
Cookie Check Status:
<?php
printf ('<font color="#%s">%s</font>
;',
$status ? "00FF00" : "FF0000",
$status ? "PASSED!" : "FAILED!");
?>
</body>
</html>

BTW Instead of setting Location in HTTP header, I would prefer Refresh command in HTTP header (it works much better when you also use PHP4's sessions).
