Slave a tutti, avrei bisogno di un aiutino.
Ho scaricato nella sezione script php un form per effettuare la registrazione di utenti in una rea privata. Funziona tutto perfettamente però ho un problema quando in fase di registrazione sbaglio l'inserimento di dati. In pratica anche se sbaglio le password, o la mail nn è valida si registra lo stesso il nuovo utente, ma non dovrebbe essere così. Può qualcuno dare un occhiata a questo codice, magari è una sciocchezza che nn riesco a trovare
