how do you save multiple variables in a multiple page form to $_SESSION
in order to retrieve them later...?

Re: $_sessions
Quinonez,
I assume you are asking how to set and use sessions. In order to use
sessions you must put the following at the very top of every page.
<?php session_start() ; ?>
Once you have done that you can use sessions on the page. Now to set a
session you do the following
$_SESSION['name']="John";
This will set the session named, "name" with the value of "John." Then
you could echo it back out like so.
echo $_SESSION['name'];
and it would print out the word, 'John.' I hope this is what you
wanted. :)

Re: $_sessions
it does,
another question though is i have a form w. multiple variables its
actually a multiple page form and what i was wondering is if there is
away other than just setting up a $_SESSION['variablename'] for each
variable is there a way to have it save itself so that i can call at
the end of the form

Re: $_sessions
I guess you could do something like the following. On your html page
with all of the forms you could make the name attribute to a number
starting from 0 and going up. Here is an example of what I mean.
--------------[ HTML File ] -----------------------------
<!----Messy HTML Code. Example only.--->
<html>
<head><title>Te st Page</title></head>
<body>
<b>Enter your name: </b><input type="text" name="0">
<b>Enter your phone: </b><input type="text" name="1">
<form action="file.ph p" method="post">
<input type="submit" value="Submit"> </form>
</body></html>
---------------------------------------------------------------------
---------------[File.php]--------------------------------------------
<?php
session_start() ;
for($m=0;$m<2;$ m++)
{
$_SESSION['$m']=$_POST['$m'];
}
?>
----------------------------------------------------------
The above code should work. If it dosen't then it's because $m dosen't
need to be in the '. This code is only to give you an example of what I
mean. :)

==== page1.php
$_SESSION['page1'] = $_POST;
==== page2.php
$_SESSION['page2'] = $_POST;
echo $_SESSION['page1']['name'];

Try
==== page2.php
echo '<pre>'; print_r($_SESSI ON['page1']); echo '</pre>';

Also, consider using an object.
