The problem here is this:
<input type='text' name=$qty[$i]
------------------------^^^^
Change it to:
<input type='text' name="qty[$i]" value="{$qty[$i]}"

I wonder, are $name,$price and $qty set variables, and is so, are they
scalars referring to the variable in the POST array?
Add this on top of every code to get hints:
ini_set('display_errors', true);
error_reporting(E_ALL|E_STRICT);
With the above change, the array of quantities should be in $_POST['qty'].
When you're not sure wether the $_POST array (or any variable for that
matter) contains the right data, use var_dump($_POST); (or any other
variable name offcourse) to check what kind of data it holds.

No, only variables put explicitly in an input (/textarea/select) are
posted, currently the only variables you send is the $qty array step for
step. And you don't send it as a value at the moment, but as the name,
which I would not recommend :-). Only scalars (string, integers,..) can be
posted, no arrays or objects. (Unless you cast them to a string with for
instance serialize, but that's not necesarry for your code.
