Hallo Leute,

ich bin jetzt nicht unbedingt der Php-Profi... Habe mir im Forum zusammengesucht, dass es eine Möglichkeit gibt Kategorien nur dann anzuzeigen, wenn sie zum einen "public" sind und zum zweiten ein passender User angemeldet ist. Also die Kategorie soll nur angezeigt werden, wenn ein Berechtigter User angemeldet ist.

Jetzt hab ich eine Navigationsmodul, weiß aber nicht, wie ich das anzupassen habe.


Wäre echt cool, wenn mir jmd. behilflich sein könnte.

Vielen Dank

Christian

Hallo emergence,

erst einmal danke für deine Hilfe...
Meine Frage wäre noch, wieso der code nur in 4.4.x laufen kann?

danke

[emergence]

Meine Frage wäre noch, wieso der code nur in 4.4.x laufen kann?

zwei gründe
startartikel funktionalität hat sich in der 4.5.x serie geändert
ein b.is_start = "1" bringt beim nützen dieser neuen funktionsweise nichts..

im 4.5.x gibts ebenfalls ein etwas anderes frontend user system
abfragen via have_perm etc. werden in weiterer folge nicht mehr 100%ig korrekt funktionieren...
