New problem with PHP plugin

Yes but you get the filtered content only the first time when the page is loaded syncronously because the class is initialized then. If you click on the module's refresh icon you will see that your echoed content is not reloaded. So it's not possible to retrieve it asyncronously.

I hope this makes sense, otherwise you will just have to accept it's not possible to do and that it's not supported. As I mentioned before, you can use $selectedid to filter the results, but you can't use variables from the query string.

Arfff  :'(  :'( :'(

So I have to build 1 plugin per category. And if i wanted to offer a filter by author... same way

One last question, please. I'd like to change the refresh picture. How can i do this ?

Currently it can't be changed, it's hardcoded in the module. You don't like it? I could put it externally in the next version maybe.
