使用PHP DOM获取提交的值

Question

I want to get the values that belong to the answers of a test. There could be any number of questions. A question has the HTML:

<form method='post' action='calificar.php'>

<div class='pruebaAlumno'>

    <h5>Pregunta 3</h5>
    <h3>¿Que factores definen la capacidad de una persona?</h3>

    <input type='checkbox' name='respuestaAlumno[]' 
                      value='Voluntad'> Voluntad <br>
    <input type='checkbox' name='respuestaAlumno[]' 
                      value='Cultura'> Cultura <br>
    <input type='checkbox' name='respuestaAlumno[]' 
                      value='Hábitos'> Hábitos <br>
    <input type='checkbox' name='respuestaAlumno[]' 
                      value='Habilidad'> Habilidad <br>
    <input type='checkbox' name='respuestaAlumno[]' 
                      value='Perfil'> Perfil <br>
    <input type='checkbox' name='respuestaAlumno[]' 
                      value='Dones'> Dones <br>

    <input type='hidden' name='idPregunta' value='41'>
    <input type='hidden' name='tipo' value='C'>
             </fieldset>

            </div>  <div class='calificar'>
                    <input type='submit' name='calificar' value='enviar' >
                </div>
            </form>

I want to get

1. Answer (respuestaAlumno)
2. questionID (idPregunta)
3. type (tipo)

from each question.

Then I want to save the data in an array.

A test can have as many questions as the teacher wants. The form has one submit button.

I´ve tried to get the data in different ways. Using JS DOM. Using POST. I´ve found some PHP DOM tutorials but them all teach how to modify an static HTML.
Please help me to get the submitted data from each fieldset. Thanks in advance.

Answer 1

You could format your form names like this.

First question

name="respuestaAlumno[0][]"
name="respuestaAlumno[0][]"
...
name="idPregunta[0]"
name="tipo[0]"

Second question

name="respuestaAlumno[1][]"
name="respuestaAlumno[1][]"
...
name="idPregunta[1]"
name="tipo[1]"

You would end up with three arrays in your $_POST.
