Date|Time returning error

Question

I have the Model class down below:

namespace classes\mvc\modelos;

use \DateTime;

class ClientesModelos {

    private $idClientes, $data, $nome, $sobreNome, $nascimento;

    public function __construct (
        string $_nome, 
        string $_sobreNome, 
        DateTime $_nacimento
    ) {         
        $this->data        = date('Y-m-d');
        $this->nome        = $_nome;
        $this->sobreNome   = $_sobreNome;
        $this->nascimento  = $_nacimento;
    }       

    public function setIdClientes(int $_idClientes) { $this->idClientes = $_idClientes; }

    public function setData(DateTime $_data): DateTime { $this->data = $_data; }

    public function getIdClientes() : int { return $this->idClientes; }

    public function getData() : DateTime { return $this->data; }

    public function getNome() : string { return $this->nome; }

    public function getSobreNome() : string { return $this->sobreNome; }

    public function getNascimento() : DateTime { return $this->nascimento; }

}

And also the Classe Dao with the method insert:

public function inserir (ClientesModelos $_cliente) : bool {

    $sql = 'INSERT INTO clientes (data, nome, sobreNome, nascimento, documento, telefone, celular, email, senha, bloqueio) VALUES (?,?,?,?,?,?,?,?,?,?)';

    $inserir = $this->pdo->prepare ($sql);

    $inserir->bindValue (1, $_cliente->getData());
    $inserir->bindValue (2, $_cliente->getNome());
    $inserir->bindValue (3, $_cliente->getSobreNome());
    $inserir->bindValue (4, $_cliente->getNascimento()->format("Y-m-d"));

    return $inserir->execute();

}       

I summarized at the maximum to get just the necessary to the reply of doubt.

The problem:

When squeegee to index php.

$cliente = new ClientesModelos (
         'Carlos',
         'Alberto',
         new DateTime('1970-12-20')
);

$clienteControle = new ClientesControles();

$clienteControle->inserir ($cliente); 

Method of Control class:

public function inserir(ClientesModelos $_pessoa) : string {

    if ( !is_object($_pessoa) ) return 'Uma pessoa precisa ser passada como parâmtro' ;
    else return $this->ClientesDao->inserir($_pessoa)  ? 'Cadastro efetuado com sucesso' : 'Erro no processo do cadastro';

}

Method insert of class Dao:

public function inserir (ClientesModelos $_cliente) : bool {

    $sql = 'INSERT INTO clientes (data, nome, sobreNome, nascimento, documento, telefone, celular, email, senha, bloqueio) VALUES (?,?,?,?,?,?,?,?,?,?)';

    $inserir = $this->pdo->prepare ($sql);

    $inserir->bindValue (1, $_cliente->getData());
    $inserir->bindValue (2, $_cliente->getNome());
    $inserir->bindValue (3, $_cliente->getSobreNome());
    $inserir->bindValue (4, $_cliente->getNascimento()->format("Y-m-d"));

    return $inserir->execute();

}       

I get the next error:

Fatal error: Uncaught Typeerror: Return value of classes mvc templates Customersmodels::getData() must be an instance of Datetime, string returned in D: Host jobs htdocs mvc_crud_pdo classes mvc templates Customersdelos.php:40 Stack trace: #0 D: Jobs host htdocs mvc_crud_pdo classes mvc templates Clientesdao.php(20): classes mvc templates Clientsmodelos->getData() #1 D: Jobs host htdocs mvc_crud_pdo classes mvc controls Clientscontroles.php(22): classes mvc templates Clientsdao->insert(Object(classes mvc models Clientesmodelos)) #2 D: Host jobs htdocs mvc_crud_pdo classes mvc visoes Clientesvisoes.php(31): classes mvc controls Clientescontroles->insert(Object(classes mvc templates Clientesmodelos)) #3 D: Host jobs htdocs mvc_crud_pdo index.php(18): classes mvc visoes Clientesvisoes->html() #4 {main} thrown in D: Host jobs htdocs mvc_crud_pdo classes mvc templates Clientesmodelos.php on line 40

However the object returns the Datetime correctly.

Answer 1

The error is in the file type to insert into the database.

To enter the date in the database, you have to send as string, usually in the format Y-m-d and the return of the method getData() returns the object DateTime.

You can change the method getData()

public function getData() : string { return $this->data->format('Y-m-d'); }

or later on the DAO

$inserir->bindValue (1, $_cliente->getData()->format('Y-m-d'));

equal is at birth

$inserir->bindValue (4, $_cliente->getNascimento()->format("Y-m-d"));
