PHP FORMS and $_SESSIONS

i have a 7 page form and many many many variables..
i cant figure out how to get the variables to move from each page and
show after it is submitted. I can get the last page of the form to show
on the action page but not any of the other pages before that.

Should i be entering every single variable from each page into a
$_SESSION['varname']

or is there an easy way to do it..
the script i am using on the action page is:

<?
foreach ($_POST as $_SESSION['field'] => $value)
{
echo "$field: $value<br>";
}
?>

and that works for the last page of the form but not anyother?
please help
Thanks

That's a possibility. You could also echo all variables from the
previous page in hidden fields in the next page, like this:

foreach ($_POST as $varname => $value) {

$value = function_you_should_write_to_escape_value($value);
echo "<input type=\"hidden\" name=\"$varname\" value=\"$value\" /> ";
}

Note that you can't have variables with the same name on different pages
if you use this technique.

The more orthodox approach is to use hidden form fields. The easiest way to
do this is to save the $_POST array of each submit in $_SESSION.

form1.php:

$_SESSION['form1'] = $_POST;

form2.php:

$_SESSION['form2'] = $_POST;
