Supporto » Sviluppare con WordPress » plugin widget weather

  • Salve ha tutti devo sviluppare un plugin che crei un widget meteo sto usando come servizio di apikey : https://www.wunderground.com/member/api-keys questo è il mio script non funziona 🙁 potete aiutarmi per favore?
    Il plug in dovrebbe fungere cosi’ :
    – creo un widget da inserire in side bar
    – do la possibilità all utente di inserire Titolo / citta / apikey
    – mi dovrebbe ritornare la temperatura etc etc della citta richiesta

    non succede niente sembra come se l apikey non funzionasse
