Problem passing value to PHP variable with Ajax

I know it must be a frequent problem and everything, but I searched in several places and could not fix my problem:

In the project I'm working on, there's a javascript function in which a variable called codigo gets a certain value.

So when a button is clicked, the value of the codigo variable must be passed to a PHP variable for insertion into the database.

The problem is that I can not do this transfer with the values.

Here is the part where the button is

<input  type="submit" name="btnEnviar" onclick="ConfirmarAssinatura();" class="btn btn-primary btn-lg" value="Confirmar Assinatura"/>

Here's the part in Javascript:

    function ConfirmarAssinatura(){


    $.ajax({

      url:'tela-planos.php',
      type:"POST",
      cache: false,
      data: { 'cod': codigo },
      success: function (){
        alert (codigo)
      },
      erro: function(result){
        alert('errou')
      }

    });


  }

And here's the part of the php code where you'll do the action:

if (isset($_REQUEST['cod'])){

// executa o resto do código.

}

The problem is that it is not working. Can anyone help me?

The variable code was not defined. Now she is getting the value of her input, which is Confirm Signature right now. In your PHP code you will have something like:

echo $_POST['cod'];

This will print on the Confirm Signature

function ConfirmarAssinatura(){
    var codigo = $('#myinput').val();
    console.log(codigo);
    $.ajax({
        url:'tela-planos.php',
        type:"POST",
        cache: false,
        data: { 'cod': codigo },
        success: function (data){
            alert (data)
        },
        erro: function(result){
            alert('errou')
        }
    });
}
