Trying to hide categories with special name and without viewable albums ...

[berlant]

My Coppermine gallery (http://photos.berlant.fr, v 1.4.10) is managed as described at the end of this post (list of categories and albums).

- in a first part, the free access area, which could be wieved without registration (public area) (not completely fed for the moment)
- in a second part, a restricted access area, which could be accessed only with registration of a private login with dedicated access rights

My problem: I would like that
-   non registred users could not view categories of the private area (which seems to be empty because no albums are viewable by them)
-   registred users could not see categories which only contains albums non viewable by them in the concerned caterory


I know that it is not possible to restrict access to categories or to hide it. But I have searched in the forum and I have read the following post:  http://forum.coppermine-gallery.net/index.php?topic=20047.0

I have tried:
       - the empty categories are not diplayed, then
             -   non registred users could not view categories of the private area
             -   registred users could not see categories which only contains albums non viewable by them in the concerned caterory
       -   but my structuring categories (private / public, year 200x, ...) which does not contains any albums and are used only for manage and sort the different topics are not displayed too
=> this solution does not fix my problem

But this post gives me an idea. I would like to add the following control in the code area (<!-- BEGIN catrow_noalb --><!-- END catrow_noalb -->) of the theme.php file:
- if category name contains a specified keyword ("HIDDEN", for example) then we don't display this category
- if category name does not contain the specified keyword, so it is displayed like in the default code
=> it will allow me to use a keyword in some special categories, and:
   - structuring categories will still be displayed
   - allowed users will continue to access to the restricted categories, because they are allowed to access to specified albums and "catrow" code part is not modified
   - but unallowed users won't see them, due to the modification of "catrow_noalb" code part

At your mind, how to add this control? Because it seems to me that the specified part of code is in HTML, and I don't know exactly how to insert PHP code in the area (I'm not beginner but I don't use it since a lot of time). Could somebody help me to start this?

Do you have any other idea which could solve my "problem"?
I hope:
- to be on the right topic list; if not move my request to other one.
- that you have understand my problem (sorry for my english) ... If necessary, I could try to explain it better


Thxs by advance for your help
Best Regards
JP BERLANT
