  • You edited the question but did not give the feedback, It was error at the time of putting in the OS or was wrong even?

  • I returned the value and it still didn’t work

  • this error appears : "Notice: Undefined Property: Pessoa::$calcularImc in C: xampp htdocs exemploFormulario php classes Pessoa.php on line 69" And line 69 is where this: <b>imc</b>: $this->calcularImc<br>";

  • Put the error in the article, it will be easier to view. The error is here: $this->calcularImc You are running as if it were a property, but it is actually a method. Switch to $this->calculator()

  • I just did that, but is appearing the () as a result.

  • Try like this <b>imc</b>: ". $this->calcularImc()." <br>";

  • tried and gave the error: Fatal error: Uncaught Argumentcounterror: Too few Arguments to Function Pessoa::calcularImc(), 0 passed in C: xampp htdocs pw1 exemploFormulario php classes Pessoa.php on line 69 and Exactly 2 expected in C:xampp htdocs pw1 class For exampleFormulario php classes Pessoa.php:49 Stack trace: #0 C: xampp htdocs exemploFormulario php classes Pessoa.php(69): Pessoa->calcularImc() #1 C: xampp htdocs exemploFormulario php system.php(9): Pessoa->exibir() #2 {main} thrown in C: xampp htdocs exemploFormulario php classes Pessoa.php on line 49

  • thank you very much for helping but I managed to resolve with the reply of the Oberto

The error is in your calculator methodImc which takes 2 parameters and you are not passing. It has two solutions.

The first

Replace in your display method:

$this->calcularImc for {$this->calcularImc($this->peso, $this->altura)}

The second solution which is the most recommended

Modify your calculator method to use attributes:

public function calcularImc()
{
    return $this->peso/($this->altura * $this->altura);
}

And modify your display method:

$this->calcularImc for {$this->calcularImc()}
