The page you are talking about is just using a filter if there is a "view parameter" in the URL, generated by the html form. They probably also use some extra module redirection to receive the request and finally show a standard view template.
But you're not explaining your needs neither your problem. You should make a more concrete question...
Thank you guys..
I found how to do the filtering....All I needed is the form with the hidden input with name=DestinationURL. Then some template code to do the fetching of data on post back.
Took me ages to find enough information on how things work. Specially that the page I posted uses someting ezposttoview which has been deprecated.
I know it has been a while since my last post on this subject.
We have recently published additional solutions and information
about this subject in an example module extension solution called bcposttoview. http://projects.ez.no/bcposttoview
It includes a couple of different custom module views
by default to chose from which process and redirect differently based on different needs and situations.
Ment as a useful out of the box solution or example solution for the problem at hand.
This solution focuses mostly on the backend redirection rather than the frontend templating.
We have also added an related article
into ezpedia about the subject / solution, http://ezpedia.org/ez/solution_converting_html_form_post_variables_into_url_view_parameters
Hopefully more examples provided by the community of how to build these commonly desired solutions will aid others in the future.
