Questo plugin dimostra come farlo. Da notare, i passaggi coinvolti sono:
- Registrare ogni impostazione per aggiornare / cambiare
- Quando si crea il controllo, passare un array come argomento di impostazione
- Durante il rendering degli input, passare la chiave delle impostazioni per collegare e valutare
- La chiave delle impostazioni non è il nome dell'impostazione, ma gli indici dell'array, ad es. 0, 1, 2
- Accedi alle impostazioni registrate su un controllo tramite
$this->settings
Ecco il codice:
