Reusing Find/Add media dialog

[Behrad Zari]

I have a form in which I want to let the user find or add a media resource to attach to my form, I will use that medium url in my services.

I checked admin templates, something like admin_connect_media_dialog helps me but without the connection to subject_id since I have no

subject resource and want to find/add media to return me the selected/uploaded media resource id. How can I achieve this reusing the admin templates?

and How can I copy the media absolute url using m.media[id].filename to a variable!? (like the usage in url scomp)

I tried 

action=dialog_open with template="_action_dialog_connect.tpl" and callback="$.my_callback" 

to get the uploaded resource (upload works) 

but find tab doesn't show any results (nothing to select)!!!
