Related Links, Darstellung im Content ändern
Eingetragen von 0etzi (43)am 01.09.2008 - 09:50 Uhr in
Hallo,
ich nutze Related Links für eine Linkliste. Eingestellt habe ich, dass diese am Seitenende aufgelistet werden.
So weit klappt das, nur fügt das Modul diese Links zusätzlich noch mal darunter zeilenweise ein.
Wie kann man das abschalten?
Gibt es einen Möglichkeit, diese Linkliste auch an beliebiger Stelle in einer Seite einzufügen?

Gibt es einen Möglichkeit, diese Linkliste auch an beliebiger Stelle in einer Seite einzufügen?
Sollte prinzipiell und auf verschiedene Arten moeglich sein.
Schaue Dir im Modul die Funktion an die letztenendes die Links ausgibt.
Moeglichkeiten:
- Diese Funktion koennte man im Nodetype-Templatekontext ansprechen.
- Diese Funktion in einem View ansprechen (PHP Code im Views Header oder Footer).

quiptime
Nur tote Fische schwimmen mit dem Strom.
Wie oder wo finde ich diese Funktion?

Habe in der Datei links_related.module danach gesucht, aber wenn ich dachte, jetzt habe ich die richtige Funktion raus genommen, war die Seite weg.
Kann mir da jemand auf die Sprünge helfen?
