Form Symfony e problema array

[enigma83]

come da titolo ho un problema di conversione array to string nel controller di symfony posto l'action:

Codice: Seleziona tutto

	public function createAction(Request $request)
	{
	        $nutrizionista = new Nutrizionisti();
        	$form = $this->createFormBuilder($nutrizionista)
    		->add('idRuoli', 'integer')
    		->add('RagioneSociale', 'text')
    		->add('Cognome', 'text')
    		->add('Nome', 'text')
    		->add('Indirizzo', 'text')
    		->add('CAP', 'integer')
    		->add('Localita', 'text')
    		->add('Telefono', 'text')
    		->add('Cellulare', 'text')
    		->add('Mail', 'text')
    		->add('Facebook', 'text')
    		->add('Linkedin', 'text')
    		->add('Google', 'text')
    		->add('CodiceFiscale', 'text')
    		->add('PartitaIva', 'text')
    		->add('OrdineIscrizione', 'text')
    		->add('NumeroIscrizione', 'text')
    		->add('CittaIscrizione', 'text')
    		->add('Logo', 'text')
    		->add('Utente', 'text')
    		->add('Password', 'text')
    		->add('Active', 'integer')
    		->add('Note', 'textarea')                    	
		->add('save', 'submit', array('label' => 'Inserisci Nutrizionista'))
                ->getForm();
 
        	$form->handleRequest($request);
 
        	if ($form->isValid()) {
            		$em = $this->getDoctrine()->getManager();
            		$em->persist($nutrizionista);
            		$em->flush();
 
            		return $this->redirect($this->generateUrl('/nutrizionisti'));
        	}
 
        	return $this->render(
            		array(
                		'form' => $form->createView()
            		)
        	);


    		$em->persist($nutrizionista);
    		$em->flush();
    	}

L'errore è questo:

Notice: Array to string conversion

        try {

Devi riportare l'errore completo altrimenti non si capisce dov'è.

Comunque hai sicuramente assegnato ad una variabile che viene convertita in stringa un array.
Tirando a indovinare, è possibile che tu abbia inizializzato uno dei campi di classe di Nutrizionista ad array per sbaglio?

Qualcosa del tipo:

Codice: Seleziona tutto

class Nutrizionista {
    ...
    private $campo = array();
    ...
}

oppure:

Codice: Seleziona tutto

class Nutrizionista {
    ...
    public __constructor(){
        $this->campo = array();
    }
    ...
}
