Answer 1

Hola, para enviar datos por un formulario tienes que usar el atributo name, no el atributo id.

Para que te funcione, cambia los inputs de cerdo y chapeta añadiendo el atributo name:

<input type="text" class="form-control" id="cerdo" name="cerdo" required>
<input type="text" class="form-control" id="chapeta" name="chapeta" required>

Así te debería funcionar.
