bidden

I'm a little stuck... Click here to teach me more about this clue!

'ordered' is the definition.
(I've seen this before)

'new leader with extra heart?' is the wordplay.
'new leader' becomes 'bin' (I can't explain this - if you can you should believe this answer much more).
'with' is an insertion indicator.
'extra' becomes 'added' (similar in meaning).
'heart?' indicates the central letters (I've seen 'heart of' mean this).
The middle of 'added' is 'dde'.
'bin' enclosing 'dde' is 'BIDDEN'.

Can you help me to learn more?

(Other definitions for bidden that I've seen before include "Commanded (to do something)" , "Asked" , "Ordered (to)" .)
