What I am setting up is a login page that after loging in a cookie is set from the username field.
I am using dreamweaver MX form all of my programing as I know very little about php.
This is what I have, and for some reason it don't work:

<?
if (isset($HTTP_POST_VARS['user'])) {
setcookie("user", $HTTP_POST_VARS['user'], time()+86400*1);
}
?>

Im not geting an error of any sort and it is setting a cookie that is called PHPSESSID and it stores a bunch one letters and numbers. Im not sure what eles you would like to know. If you would like to see it in action (I do know that you cant see the php) you can go to pedigree.whitegloveweb.com and log in as "test" with a password of "test" if you would like more info please just message me.

That file is the cookie file, you are not having a problem with the cookie itself but with the login verification.  Explain what the problem is exactly, is it forcing people to have to login for each page?

If so you need to create the script for each page (or put on one page and include on each page) that will first check to see if logged in and if not display login form else do everything else.

Well, after playing with it more I did find out that you are sort of right andriv. I took out the user login script that vairfies the user via mysql table and I got a good cookie that worked so it is in my userlogin script that is messing things up.
If you want to see the hole page here it is maybe that will help all of you out:

<?php require_once('Connections/a.php'); ?>
<?php
// *** Start the session
session_start();
// *** Validate request to log in to this site.
$FF_LoginAction = $HTTP_SERVER_VARS['PHP_SELF'];
if (isset($HTTP_SERVER_VARS['QUERY_STRING']) && $HTTP_SERVER_VARS['QUERY_STRING']!="") $FF_LoginAction .= "?".$HTTP_SERVER_VARS['QUERY_STRING'];
if (isset($HTTP_POST_VARS['user'])) {
  $FF_valUsername=$HTTP_POST_VARS['user'];
  $FF_valPassword=$HTTP_POST_VARS['password'];
  $FF_fldUserAuthorization="";
  $FF_redirectLoginSuccess="index2.php";
  $FF_redirectLoginFailed="retry.php";
  $FF_rsUser_Source="SELECT username, userpass ";
  if ($FF_fldUserAuthorization != "") $FF_rsUser_Source .= "," . $FF_fldUserAuthorization;
  $FF_rsUser_Source .= " FROM users WHERE username='" . $FF_valUsername . "' AND userpass='" . $FF_valPassword . "'";
  mysql_select_db($database_a, $a);
  $FF_rsUser=mysql_query($FF_rsUser_Source, $a) or die(mysql_error());
  $row_FF_rsUser = mysql_fetch_assoc($FF_rsUser);
  if(mysql_num_rows($FF_rsUser) > 0) {
    // username and password match - this is a valid user
    $MM_Username=$FF_valUsername;
    session_register("MM_Username");
    if ($FF_fldUserAuthorization != "") {
      $MM_UserAuthorization=$row_FF_rsUser[$FF_fldUserAuthorization];
    } else {
      $MM_UserAuthorization="";
    }
    session_register("MM_UserAuthorization");
    if (isset($accessdenied) && false) {
      $FF_redirectLoginSuccess = $accessdenied;
    }
    mysql_free_result($FF_rsUser);
    session_register("FF_login_failed");
      $FF_login_failed = false;
    header ("Location: $FF_redirectLoginSuccess");
    exit;
  }
  mysql_free_result($FF_rsUser);

}

What PHP version are you running?
you might want to do <?phpinfo()?> to know this.

Anyhow, why not to use sessions? they are much easier. Check out here: www.php.net/sessions

Hope this helps...

<?php

session_start(); // start php session handling

if (strlen($_REQUEST["user"]) > 0) {
  // set the session variable "user" to the user
  $_SESSION["user"] = $_REQUEST["user"]
}


// $_SESSION["user"] will exist if they have just
// logged on, or if they have logged on before

if ( ! isset($_SESSION["user"]) ) {
  print $login_page_html;
  exit;
} else {
  print $std_content_page_html;
}

?>

but please .. http://www.php.net/sessions .. read more about php sessions before using them.

I had the same problem.
Try this:

function BakeIt() {
       
        var cookieData = document.form1.user.value;

        if (cookieData != null) {

            var cookieName = "user";

            var days = 1;

            var expires = new Date ();
            expires.setTime(expires.getTime() + days * (24 * 60 * 60 * 1000));

            SetCookie(cookieName, cookieData, expires);
        }

        window.location = "index2.php";
    }

    function SetCookie(cookieName, cookieData, expireDate) {
        document.cookie = cookieName + "=" + escape(cookieData) + "; expires=" + expireDate.toGMTString();
    }
