ZendFramework 2 - How to edit form data with fieldsets? - php

Question

I'm trying to learn ZF2, and I am not able to edit the data in the edit form. I have two classes Pessoa and Endereco and I have a form to edit the data, but it only changes the data related to Pessoa, those about the Endereco is stored as blank.
And when trying to add a new record (add action) i get the following error:
Fatal error: Cannot use object of type Pessoa\Model\Pessoa as array in /opt/lampp/htdocs/cad/module/Pessoa/src/Pessoa/Model/Pessoa.php on line 23
Pessoa.php

$this->dtNasc = (!empty($data['dtNasc'])) ? $data['dtNasc'] : null;
//$this->getEndercoInstance();
$this->endereco->exchangeArray($data);
/*if (isset($data["endereco"]))

Please, can anyone help me?

Answer 1

So let me explain better my self,
You are sending an array to the method
exchangeArray($data);
but $data is not an array;
Example of Array:
$data['username'] = 'someuser';
$data['email'] = 'someuser#someuser.com';
$data['phone'] = '235346346';
print_r($data);die;
//output:
//Array ( [username] => someuser [email] => someuser#someuser.com [phone] => 235346346 )
Example Object:
$data['username'] = 'someuser';
$data['email'] = 'someuser#someuser.com';
$data['phone'] = '235346346';
$object = (object)$data;
print_r($object);die;
//Output
//stdClass Object ( [username] => someuser [email] => someuser#someuser.com [phone] => 235346346 )
So i reproduce part of the code you have above and i gave to the method exchangeArray($data); of type Array and i got no errors then i gave to the method exchangeArray($object); and the result was
Fatal error: Cannot use object of type stdClass as array in /blah/blah/... on line 39
So Basically in your method you are passing $data of type object and not Array
