accessing cookies????

[Anon]

hello
i am new to php and i find that this forum is giving out a very good support, so i hope those experts out there can help me with cookies. i've been figuring out the problem for the past 3 days but still can't find whats my problem. my source is given below

//main.html

<form method=post action='test2.php'>
LOGIN<input type=text name=user size=20><br>
PASSWORD<input type=text name=password size=20><br>
<input type=submit value=submit>
</form>

//test2.php

<?
require 'function.php';
deleteCookies();

if(!authenticateUser($user, $password) )
{
header("Location:http://$HTTP_HOST/$DOCROOT/display1.php");
}
else
{
setcookie('cookie_user', $user);
setcookie('cookie_password', $password);
header("Location:http://$HTTP_HOST/$DOCROOT/display2.php");
}

?>

//display2.php
<?

echo $cookie_user;
echo $cookie_password;
?>

//display3.php
<?

echo '$cookie_user';
echo '$cookie_password';
?>

if the authnticate is true display
$cookie_user$cookie_password

if the authentication is false it displays
Warning: Undefined variable: cookie_user in D:\PROJECT\testing\display2.php on line 2
Warning: Undefined variable: cookie_password in D:\PROJECT\testing\display2.php on line 3

what i know is that once we set a cookie, the cookie can be access anywhere until the browser is close but why does the display2.php and display3.php doesn't displya the values of the cookies_user and cookie_password.

thanks

ok this is a big one for PHP so remember it... anything put in 's such as
echo '$cookie_user';
will not expand... in stead put it in "s like so...
echo "$cookie_user";
Please let me know if this doen not fix the problem

Hello Lone Wolf,

I think your own logic is throwing you.

First of all where does display3.php fit in?

And where is the code for display1.php?

As I see it your your file names are a bit screwed up. If it is so:

//test2.php

<?
require 'function.php';
deleteCookies();
if(!authenticateUser($user, $password) )
{
header("Location:http://$HTTP_HOST/$DOCROOT/display2.php");
}
else
{
setcookie('cookie_user', $user);
setcookie('cookie_password', $password);
header("Location:http://$HTTP_HOST/$DOCROOT/display3.php");
}

?>

//display2.php
<?
echo $cookie_user;
echo $cookie_password;
?>

//display3.php
<?
echo '$cookie_user';
echo '$cookie_password';
?>

Then you're getting an error because you're sending the user to display2.php without setting any cookies.

Could that be the problem?

hello
Scott, i think don't get what i want from the code. What i wan to do is to set the cookies and retrieve it when i access the other page.

and Travis, u asked me to try using "s. but still having the same problem. error message undefined variable for the cookies name
thankz
