Variante von AhA

  • Nur angemeldete Benutzer dürfen Seiten hinzufügen
  • Erstellt wird automatisch eine Unterseite des angemeldeten Benutzers
  • Schreibrecht nur beim Benutzer
  • Exisiert die Seite bereits, erscheint eine Fehlermeldung
  • Der header ist global
  • Gibt man in der Seitenvorlage (zum Beispiel am Schluss) ::: ein, werden diese drei Doppelpunkte bei der Übergabe durch vier Doppelpunkte ersetzt. Wenn der Benutzer seine neue Seite erstmals editiert und wieder speichert, werden die vier Doppelpunkte durch den Benutzernamen ersetzt -> backlink!
  • Wenn kein Seitentitel eingegeben wird, bleibt die Aufforderung, man solle einen Seitentitel eingeben

legacy code, incompatible with WackoWiki 6.x

Comments

  1. TemplateInsert revision

    First version works, the second version looks like it started life with Wikka, and most of the functions will need to be converted to Wacko functions.
