Here is what I've been doing with PHP. If this isn't clear enough, let
me know.

When the user submits page1.php, it posts to itself
(page1.php?id=5&name=randal&company=covansys&save=Save). If the values
check out OK, then I forward the user to page2.php with the header()
function. I simply attach the query string (minus the save action) to
the page2.php (page2.php?id=5&name=randal&company=covansys).

Then I populate hidden fields in page2.php with the necessary values.

If I have to go back to page1.php, then I am going back to
page1.php?id=5&name=randal&company=covansys&save=Save. Because "save" is
true, the script pulls the values from the string and puts them into the
fields.

<input type="text" id="name" name="name" value="<?=$name ? $name : "";
?>" />
