How to access data from the form in object orientation

Question

How do I receive information coming from POST form, so that these data enter a decision structure, Example: I have an abstract class with the function of entering the system, but in the form the user has to mark if he is employee or delivery, the class that inherits the method enter before anything else need to know if this login is the employee of the company or the courier, as both will be directed to different screens.

require_once 'Log in.php';

$logging in = new Log in($user, $password); $logging ->setUsuario($_POST['usuario']); $logging->setSenha($_POST['password']);

PAGE LOGIN:

public function __construct($usuario, $senha) {
    $this->usuario = $usuario;
    $this->senha = $senha;

}

function getUsuario() {
    return $this->usuario;
}

function getSenha() {
    return $this->senha;
}

function setUsuario($usuario) {
    $this->usuario = $usuario;
}

function setSenha($senha) {
    $this->senha = $senha;
}


abstract public function Entrar($usuario, $senha);
abstract public function Sair();     
abstract public function Erro();

}

LOG IN

class Logar extends Login {

private $con;

public function __construct($usuario, $senha) {
    parent::__construct($usuario, $senha);
    $this->con = new Conexao();
}


public function Entrar($usuario, $senha) {
    parent::Entrar($usuario, $senha);
    echo "Método entrar esta funcionando";
}

public function Sair(){
    echo "Saindo";
}

public function Erro() {
    echo "Erro";
}

}

Try to leave your method like this:

public function Entrar() 
{
    echo $this->getUsuario() . ' - ' . $this->getSenha(); // Imprime usuário e senha recebidos p/ testar
}

In the object, in the scope where your code is being executed, you call the method Entrar() if the condition is true:

if (isset($_POST['botao']) && $_POST['botao'] == 'Login Funcionário')
{
    $obj = new Logar(); // Instancia o objeto da classe Logar

    $obj->setUsuario($_POST['usuario']); // Atribui usuário
    $obj->setSenha($_POST['senha']); // Atribui senha
    $obj->Entrar(); // Chama o método Entrar()
}

Don’t forget to process the data from $_POST.

EDIT:

$usuario and $senha are given from $_POST? You are assigning these values to these variables before?

If yes, then if you’re passing $usuario and $senha for the constructor method, so it is not necessary to call again: $logando->setUsuario($_POST['usuario']); and $logando->setSenha($_POST['senha']);, because there you call the __construct() of the mother class and already assigns values to the properties.

Another thing I found is in your method Entrar() of the class-daughter (Log in). In it you are calling the method Entrar() of the mother class which is abstract through the parent::Entrar($usuario, $senha);, that is, it has no functionalities implemented.
