session variables will not pass to subsequent php code

[skypilot]

I have written some code with the following setup.

menu.html is a pure html code with the following code for reference:

<form action="menu.php" method="post">
<input name="username" type="text">
<input type="submit" value="Press Here">
</form>

==============

menu.php is only php script containing the following:

<?php
session_start();
session_register("username");
$_SESSION[$username] = $username;
echo "<SCRIPT>self.location.href='bill.html'</SCRIPT>";
?>

===============

bill.html is code to prompt for other information....not really inportant to my problem.

<form action="bill.php" method="post">
<input name="entrees" type="text">
<input type="submit" value="Press Here">
</form>

===============

bill.php contains the following

<?php
echo $_SESSION['$username']";
?>

=======

Okay.... here is the problem.....the value of $username does not get passed to the bill.php code. I can not determine why this variable is not passing as anticipated.

I hope someone can help.

Thanks

Do you have register_globals on or off? If you have them off then session_register() won't work. To be on the safe side use this for menu.php:

<?php 
session_start(); 
if(!isset($_SESSION['username']))  //check that it has not been set already
{
  $_SESSION['username'] = $_POST['username'];
}
echo "<SCRIPT>self.location.href='bill.html'</SCRIPT>"; 
?> 

And then for bill.php use:

<?php 
session_start();
echo $_SESSION['username']; 
?> 

See how you go with those modifications and check out [MAN]session[/MAN] in the good 'ol manual.

Your script won't work I think.

First give $username a value.
Then session_register("username").
$_SESSION["username"] has the value of $username;

Thank you for your input....everything is passing fine now.

However....I have a new concern. When I say that everything is passing fine, I mean variables a passing correctly, as long as the user accepts the "cookie" request that is received when $_session is called.

If the cookie is not taken, the variables are not passed along. Does anyone know how to check when a cookie has been accepted or not in this case? I can not determine where this cookie information is being stored. I tried $HTTP_COOKIE, however this did not have any value associated with it. I also checked into session_get_cookie_params, and with the poor documentation on this function in the manual, I could not get information here either.

I hope someone has a clue as to how to do this.

This I don't know. Sorry

$_COOKIE[];

Yes ofcourse, I think I didn't understand the question. Ofcourse $_COOKIE["variablename"] has the value in it.
