Jans Navigation Gruppensensitiv machen ?

Dalamar · Beitrag von **Dalamar** » So 5. Feb 2006, 17:33

Nabend Leute,

ich benutze Jans Navigation für die 4.6.x Version und würde diese gern so modifizieren, dass geschützte Kategorien ausgeblendet werden wenn ein Frontend-User nicht angemeldet ist bzw. keine Rechte hat, die jeweilige Kategorie zu benutzen.

Vielleicht hat sich schon jemand damit beschäftig und kennt einen Lösungsansatz.

Mein Problem ist, dass ich 2 Kundenstämme (also 2 verschiedene Frontend-Usergruppen) habe und die eine Gruppe nicht den Bereich der anderen Gruppe sehen darf.

Anbei das Modul:

Nimm' doch einfach das Standard-Hauptnavigationsmodul aus V4.6.x. Da ist alles schon drin und einen größeren Unterschied dürfte es nicht geben (außer, dass mehr Templates verwendet werden und das Modul z.Z. nur drei Ebenen ausgibt).

Alternativ kannst Du Dir ja die entscheidenden Stellen des Moduls ansehen (irgendwas mit Permission im Output).

Danke Dir HerrB, werde ich machen!

Dalamar · Beitrag von **Dalamar** » Mo 6. Feb 2006, 10:32

Mist, ich habe das Modul nicht griffbereit, kann es vielleicht jemand mit In- und Output posten. Danke !!!
