Hi
Sure, JDom is totally customisable, just:
- take one of the classes (and its assets etc)
- clone it
- rename it
- rename the class(es)
- make any adjustments you require such as chmod'ing the file on upload, changing path, adding js (Ajax uploader) or whatever.
Start with a class close to the type you require - so, as you're already doing, start with file class.
A good place to look at an example of customising JDom is in the tutorial:
j-cook.pro/docs/tutorials
do you need to render the file in browser or link to download?
