1. How do I add parameters to the URL? I tried to add a "page"
parameter, by appending "/page/{page number}" (such as "/page/3") to
the URL. The original URL looks like
"my.domain.name/index.php/dream/dream/action/cat/?DREAMS=2cd73545e5191345d5143dcbdf20e4fa&/1/id/12",
and with my page number it is
"my.domain.name/index.php/dream/dream/action/cat/?DREAMS=2cd73545e5191345d5143dcbdf20e4fa&/1/id/12/page/3",
but when I have function _cat(&$input, &$output), $input->page is
still null.
OK. This problem is solved now. I was not aware of the function
validate($req, &$input). I needed to add $input->page =
$req->get('page');
Uri.
