forwarding variables

[Aeros]

I have a form called page1.php and the user hits submit. I need to take the variables pass from page1.php to page2.php and do some logic with them and placing them in hidden form fields then automatically pass those variables to page3.php without any user interaction.

Whats the best way of doing this?
Thanks

Use sessions. See

Why complicate? Use $_POST.

page1.php

<form method="POST" action="page2.php">
<input type="text" name="username"><br>
<input type="text" name="password"><br>
<input type="submit" name="submit" value="Submit">
</form>

page2.php

<?
  if (isset($_POST['submit'])){

    echo 'Username: '.$_POST['username'].'<br>';
    echo 'Password: '.$_POST['password'].'<br>';
    echo 'Are this values correct?

    echo '<form method="POST" action="page3.php">';
    echo '<input type="hidden" name="userhidden" value="'.$_POST['username'].'">';
    echo '<input type="hidden" name="passhidden" value="'.$_POST['password'].'">';
    echo '<input type="submit" name="submit" value="Yes!">';

  }
?>

page3.php

<?
  if (isset($_POST['submit'])) {
    // use $_POST['userhidden'] and $_POST['passhidden'] as you wish
  }
?>

p.s.: sorry for my (sometimes) bad english

I suggested Sessions since he said:

Your method needs user interaction.

PLEASE READ THIS ENTIRE POST!! (VERY IMPORTANT)

listen to what kenrbnsn said above, but also:
1. Sessions are WAY less complicated than having user submitted forms!
2. The time it takes to generate those forms, is atleast 3 x the time it takes to use sessions.
3. The sessions will also work if the user presses "back" in his/her browser (unless your way of setting the session variables are really dumb).
- eg. no more "back to blank forms", if you use sessions.
4. And, least, but not last important:
- The way provided by jamesp0tter above, will give the user the password and the username in clear text!!

* The user can it that way just view-> code to see the password/username.. This is a REALLY big NO-NO

--> USE SESSIONS! or you will regret!
