I need to pick with the foreach of PHP, the id of the question and the reply of each answered question.

I can only get the id of the question, as I would also get the typed answer?

Man foreach

<?
 if (isset($_POST['resposta'])) {


 foreach ($_POST['id_pergunta'] as $value) {

     echo $value."<br><br>";


 }



 }
?>

I have the form like this:

<form role="form" action="" method="post">





                          <div class="row setup-content" id="step-1" style="display: block;">
        <div class="col-xs-12">
            <div class="col-md-12">
                <h3 style="color: #0093cf;text-transform: uppercase;">teste1</h3>
                <div class="form-group">

                </div>
                <div class="form-group">
                    <label class="control-label">Resposta</label>

php foreach

  • When you say you want to get the question id, do you refer to the input id attribute? Sorry, that’s not clear to me yet.

  • that’s right, take the value of the id_question and also the answer

How it comes to 2 arrays can be done as follows:

foreach(array_combine($_POST['id_pergunta'], $_POST['resposta']) as $p => $r)
{

   echo $p." ".$r.PHP_EOL;

}

array_combine - Create an array using an array for keys and another for values
