you only pass the value from the input tag you name $qty[$i], I guess
that is not what you want.

Not sure exactly what you are doing, but if the code below is the code
you use to get the values in testprocess.php, then I would expect, that
you only have a value in $adress.

You can pass everything if done right:-)
If you put the content of these vars in input fields or hidden input
fields you can pass them, but it is a lot easier to put them in a
session and just access the session on each page.

I think you haven't understood the concept. Here comes a short explanation.
To post some values to another php page you need to setup the submission
form:
<form id="whatever" name="somename" method="post" action="testprocess.php">
<input type="text" name="Surname" />
<input type="submit" name="Submit" value="Submit" />
</form>
Now as soon as you push the submit button if will send the form data to
the page you specified in action=""
Now on testprocess.php you can get this data, by quering for the field
names, in the above example you have once field called "Surname". You
get it with:
$surname = $_POST['Surname'];
So you can only fetch values from form elements, like <input,<select ..
Any text inside the form is not submitted, for example:
<td>$name[$i]</td> as you wrote in your example is no form element. So
you would have to put the value in a form element like a input box, then
it will be transfered on submission. But it is not practical to do that
if you have a bunch of values form an array unless you want to show the
user a list of values which he can select and then submit it.
So my advice don't think about complicated uses of posting content via
forms to another page, just try out how basic submission of simple input
fields work. Later on when you get to sessions you will findout that it
is much easier to store all the data on serverside inside a session that
belongs to a unique user.
