[quote author="ywftdg" date="1218441891"]I would say the typical, basic php method, would be to pass a number (or value) through the url, then use the URI helper to get those values and run your query. You could also use a more modern approach, if you need/want it, and use ajax.[/quote]Yea, I wanted to do ajax. Would it be possible to help me out on this? If ajax is too much, we can go for the non-ajax version.
