reposting data into forms

[hingis_rules]

When the user clicks on SUBMIT, they are taken to a confirmation screen which they can click an EDIT button or SUBMIT button. If they click on the EDIT button they are taken back to the first form. How do you repost the data the user entered into the first form, as I get a empty form when I click on EDIT?

Thanks

save them in a session

[jubripley]

or you could save them in hidden fields.

<input type="hidden" name="somename" value="<? print $someval ?>" />

how do you save them in a session?

[jubripley]

Use session_start() to start the session.
You put variables in your session using session_register().

You can access session variables either as globals (if you have registered globals) or throught the $_SESSION array.

example

session_start();
session_register ("foo");

$foo = 12; // stored in session
$_SESSION["foo"] = 12; // same

on some other page

print $foo; // "12" if you have registered globals
print $_SESSION["foo"];  // "12"

To end a session, use session_destroy()

see
http://www.php.net/manual/en/ref.session.php

So if I had a form that included

<input name="user id" type="text" size="12" maxlength="12">

and the user had entered "user1" as the user_id and I setup a global variable "$USER_ID" to store what the user entered. They presseSUBMIT and in the confirmation screen desiced to change the user id. so they click EDIT to return to the original form.

Is this how I reset the values in the form?

<input name="user id" type="text" value="$USER_ID" size="12" maxlength="12">

[jubripley]

Something like that, yeah.
php is case sensitive so you'll have to set $USER_ID = $user_id;
Or even better:
$USER_ID = $_POST['user_id'];

Somewhere before that you'll have to do
session_start();
session_register('USER_ID');

Is this how I reset the values in the form?

<input name="user id" type="text" value="$USER_ID" size="12" maxlength="12">

<input name="user id" type="text" value="<? print $USER_ID ?>" size="12" maxlength="12">

I've tried that and can't seem to get it to work. When I click on EDIT the form ends up blank. I put some "echo " statements at the begining of the script and the variables were blank.

Any suggestions?

Thanks
