Is there anyway of having several links in the same page pointing to the same desteny but passing diferent values without being passing those values by url then gating them in the $_GET array?
Use hidden fields within an html form and retrieve them via $_POST ?

Not possible. But if you lift your prohibition on passing via the query string (i.e. 'by url') then it becomes possible.
As blulagoon suggested, you can also pass data via POST using forms and hidden values... though it seems like GET would be rather simple, unless there's a reason you don't wish to use it (length limitation, etc.)
