Pełna wersja: Zmiana funkcji znaku oznaczenia użytkownika - DVZ Shoutbox
Aktualnie przeglądasz uproszczoną wersję forum. Kliknij tutaj, by zobaczyć wersję z pełnym formatowaniem.
wersja skryptu MyBB: 1.8.5
adres forum: www.utysia.pl
na czym polega problem (screen, opis, komunikaty, nazwa i wersja wtyczki):

Pomiędzy avatarem a nickiem jest znak "»" który wprowadza do pola tekstu "[b ]nickname[/b ]". Chciałbym aby ten znak powodował użycie pluginu DVZ Mentions - czyli zamiast wprowadzania "[b ]nickname[/b ]" wprowadzał "". Czy jest taka możliwość?

(spacje specjalnie bo bbcode jest od razu przetwarzane na formatowanie)
coś nie mogę znaleźć
