popup window

[Calahan]

I've spent a day fiddling with this problem. It must be simple but I can't get 1 solid answer that actually does what I want so here goes......
I have an index.php page with the following:

<?php
$_SESSION['entered_username'] = "";
$_SESSION['login'] = "";
$_COOKIE['cookies_enabled'] = "test_cookies_enabled";
if(strcmp($_COOKIE['cookies_enabled'], 'test_cookies_enabled') == 0)
{
  echo "Your browser is set to reject cookies, you must enable them to use this website";
}
?>

Now ALL I want to do is bring up a popup window if cookies are disabled with the message as it is above "Your browser is set to reject cookies, you must enable them to use this website".

I have looked at using Javascript but in order to do that, it would need to be on a seperate page meaning that I could put a referer in the if statement in the PHP code on the index page, but that would move them from the index page and I want to keep them there.
I know this must be really simple but clearly I'm missing the obvious. I'm running out of hair so any suggestions welcomed.....

if(strcmp($_COOKIE['cookies_enabled'], 'test_cookies_enabled') == 0)
{
echo "Your browser is set to reject cookies, you must enable them to use this website";
}
?>
instead of the above code

try breaking out of php to trigger the javascript

if(strcmp($_COOKIE['cookies_enabled'], 'test_cookies_enabled') == 0)
{
?>

<script language="javascript">
alert("Your browser is set to reject cookies, you must enable them to use this website");
</script>

<?php
}
?>

hope that helps!

Ok, 1/2 way there!!
That brings up exactly the window I need. only problem is, it brings it up all the time regardless of whether the browser is set to accept cookies or not. Can't figure out why though.
Another problem, I'm using $_SESSION as you can see in the code above which is defined in the index.php page (shown in my first post) but even setting session.use_trans_sid = 1, the SESSION variable for login is not being moved from the login page. The user is validated using the following script:

<?php
include("common.php");

if(!($link_id = mysql_connect($Host, $User, $Pass)))
{
die(mysql_error());
}
mysql_select_db($DB);

$sql = "SELECT ID FROM " . $Table . " WHERE username='" . $_POST['username'] . "' AND password='" . md5($_POST['password']) . "' LIMIT 1";
if(!($result = mysql_query($sql))) 
{
	die(mysql_error());
}
if(mysql_num_rows($result) == 1)
	{ 
$_SESSION['entered_username'] = $_POST['username'];
$_SESSION['login'] = 'yes';
header('refresh: 3; url=member.php');
echo "<h2><center>You have been validated. Please wait, logging you in. . .</h2><br>
<center>If your browser doesn't support redirection and you're still here in 3 seconds, <a href='members.php'>click here</a></center>";
	}
else 
	{
header('refresh: 5; url=index.php');
echo "<b><u><center>Login failure </b></u><br>Username/Password mismatch. Sit tight, we're sending you back to the login page in 5 seconds.<br>
If your browser doesn't support redirection and you're still here in 5 seconds, <a href='index.php'>click here</a></center>";
	}
?> 

and then killed off with this script that runs at the start of the member.php page which checks if the user has logged in.

<?php
include("common.php");

if(!($link_id = mysql_connect($Host, $User, $Pass))) 
{
die(mysql_error());
}
mysql_select_db($DB); 

if (@$_SESSION['login'] != 'yes')
{
echo "<b><u><center>You haven't logged on!</b></u><p>
<a href='index.php'>Click Here</a> to return to the login page";
exit();
}

The login process is clearly taking place and the user is being validated but the $_SESSION['login'], although being set to "yes" in the login.php page is not being carried over to the member.php page.

Any ideas?

well maybe in where your testing the $_COOKIE['cookies_enabled']

try

$COOKIE['test_cookies'] = "yes";
if(!$COOKIE['test_cookies'] == 'yes')
{
?>

<script language="javascript">
alert("Your browser is set to reject cookies, you must enable them to use this website");
</script>

<?php
}

and for the $_SESSION problem,

maybe try

if(!$_SESSION['login'] == 'yes') {
header(blah blah)
}
