OK - Here’s my code.
In /manager/frames/3ldr.php
This is replacement for the makeHTML function.
My basic idea is to 1st extract every docID plus its parents from the db and store as array - This is the first additional db call that I make.
Next make a call to get the every docID that the user has access to. This is the 2nd additional call
Now build a list of all the docIDs that lie between the accessible docID and the $parent docID as passed to the function - these are the docs which need to be displayed to allow the user to navigate to his doc.
Modify the original sql statement so that it requests these extra docs regardless of their edit/access permissions.
At the moment I just build a comma separated string for the additional docIDs - There is probably a better / more efficient way to do this.
I have done some limited testing - and it seems to satisfy my needs (eg an editor with access only to docs which are 3/4 folders deep in the tree can browse to his folders, without seeing the whole tree.
Hope this helps !
My only other thoughts are:-
On a large site the 1st request to get every docID plus parent could be a problem.
Did I read recently that there is a global in the API which stores the tree?
If so, then I should probably use this instead of requesting it myself.
