Help with Sessions

I have a web site that that has 4 pages to get information from the user.  The problem I am having I was trying to use sessions to keep the data entered on pages 1-4 then on page 5 after the user reviews their information they would submit it and it would post to the mysql database.  I can pass session information to the next page but can't keep it going to the other pages.  Here is an example.

page 1

Enter First Name:

Page 2

Enter Last Name:

Page 3

Enter Address:

Page 4

Enter State:

Page 5

Review the data built in the session array then submit and enter into database.

I know how to submit the data to the database but I can't seem to build the array even though I'm using session_start(); on every page.

I am looking for exact information here as I am knew to PHP and have purchased 3 PHP books so far yet nope give me an example to passing information like I am wanting.

Using PHP 4.3.5.5 on a windows platform but once this proto type is complete will be moving to a unix server.

Thanks

in order for session to be carried to 'other' pages you need to call session_start() on those other pages also

e.g. after page 5 you get redirect to page '6', that page 6 need to call session start() also. In case after page 5 you are doing a form submit to e.g. process_form.php the file needs to call session_start(), then within this process_form.php you can do whatever is required (in your case insert/update data to database) then can you only redirect to other pages without session_start()

To summarize:
Page 1 (session_start() required)
Page 2 (session_start() required)
Page 3 (session_start() required)
Page 4 (session_start() required)
Page 5 (session_start() required)
[form submit to process_form.php (session_start() required)]
Redirect to Page 6

I do have session_start() on every page but here is teh code from all 3 pages that I was trying to do tests with.

Page login.htm

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body bgcolor="#FFFFFF" text="#000000">
<table width="140" border="1">
  <tr>
    <td>
      <form name="login" method="post" action="login.php">
      Login: <input type="text" name="name">
      <br>
    Password: <input type="text" name="textfield2">
        <input type="submit" name="submit" value="Login">
      </form>
    </td>
  </tr>
</table>
</body>
</html>

page login.php

<?php
session_start();
header("Cache-control: private");

$name = $_POST['name'];

$_session['name']=$name;

?>

Welcome <? echo $_session['name'];?>

<a href="login1.php">Login <a/>


Page login1.php

<?php
session_start();
header("Cache-control: private");

?>

Welcome <? echo $_session['name'];?>

When I get to the last page I can't seem to get the $_session['name'] to display anything
My luck its going to be something really easy that I'm missing

Hi


You problem is very simple..... ( naming conversion ) -> lower case invalid

$_POST, $_REQUEST, $_GET, $_SERVER, $_ENV, $GLOBALS, $_SESSION, $_FILES, $_COOKIE

The above are all members of the AUTO GLOBALS -> "!!!predefined and reserved!!!"

You are using -> $_session

Which is not valid, and will not add any assigned value to the session array....

Always use what I listed above.....

So to correct your problem.....

change all of these..............

$_session['name'] = '?';

change to..........

$_SESSION['name'] = '?';


C, ya....

Thanks Fatagui that fixed me up just right.  I didn't notice the case change on the superglobals and I haven't read anything about it but that explains alot now.  Once again thanks.
