Buttons to take id_order variable in admin_order_details

[pinarello]

in a few words I could put in my order detail fieldset with the admin buttons. I tapped, after creating a form, a hook in order detail, and inserted the code in my file. tpl; Now my problem is how do you take such id_order to spend it with my button to another page with PHP? 

I have to override the controller admin_order? 

thanks
