Notes

Purpose of Mod

This mod is intended for those with open access to their TNG site but who wish to disable access to media for non-registered users. It allows access to media files only for logged-in users. If a non-logged-in user tries to access the relevant file they will see a message that informs them they are not authorised to view that file and a link to the Home page.

The method used in this mod can be applied to any php file to which one wishes to restrict access.

NOTE: The mod does not currently inhibit access to PDF media

Manual Customisation

If you wish to allow browsing of media but still disallow viewing the individual media items, you should remove the directive for browsemedia.php. Alternatively, you could limit the media restriction to browsing specific collections. The following example would only block the browsing of 'histories' for non-logged-in users:

 if(( ! $currentuser )&&($mediatypeID=="histories")) { 
     $showguest=1; 
     include("extensions/noaccess.php"); 
     exit; 
     } 

and to limit the restriction to 'histories' and 'photos':

 if(( ! $currentuser )&&($mediatypeID=="histories" || $mediatypeID=="photos")) { 
     $showguest=1; 
     include("extensions/noaccess.php"); 
     exit; 
     }

NOTE: It is not possible to use the above method to limit the viewing of individual images (showmedia.php) to a specific collection

Further Application

The principles used in the directives of this mod to limit access also can be applied to other files; for example: showlog.php; anniversaries.php; showsource.php, browsenotes.php.

Visualisation

This is how the standard Restriction Warning appears in Template 8:
