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

2. How to

2.1. Localization (optional)

put this at the end of your language file

'CreateButton' => 'Create',
'CreateNewPage' => '<b>Create NewPage: </b>',

//hacks
'YourPhrase' => 'your translation here',	

[xyz] proposed translations
[de] ...
[fr]
[ru]
