Ich habe versucht, indem ich ein Formular mit PHP machte und die Info mit Arrays, aber ich scheitere, und ich denke, ich muss jQuery verwenden, aber ich weiß nicht viel über jQuery, hoffe, Sie könnten mir helfen.

HTML-Formular:

<form method="post" action="anadirexamen.php"> 
    <div class="form-group"> 
    <label for="nombre">Nombre de Examen</label> 
    <input type="text" class="form-control" name="nombre" id="nombre" placeholder="Nombre de Examen"> 
    </div> 
<div class="form-group"> 
    <label for="descripcionexamen">Descripcion de Examen</label> 
    <input type="text" class="form-control" name="descripcionexamen" id="descripcionexamen" placeholder="Pequeña descripcion de Examen"> 
    </div> 

<div class="panel panel-default">

</div> 
    <div class="panel-heading">Respuestas</div> 
    <div class="panel-body">

    <input type="text" class="form-control" name="pregunta[][]" id="respuestas" placeholder="Respuesta 4">

</div> 
</div> 

<div class="form-group"> 
    <label for="mensajecorrecto">Mensaje Correcto</label> 
    <input type="text" class="form-control" name="mensajecorrecto" id="mensajecorrecto" placeholder="Mensaje Correcto">

    <input type="text" class="form-control" name="mensajeincorrecto" id="mensajeincorrecto" placeholder="Mensaje Incorrecto"> 
    </div> 


    <button type="submit" class="btn btn-default" name="anadir-examen">Submit</button> 
</form> 

PHP anadirexamen.php:

<?php 
session_start(); 

if(isset($_POST['anadir-examen'])) 
{ 
    $nombre = trim($_POST['nombre']); 
    $descripcion = trim($_POST['descripcionexamen']); 
} 

$arr = array(
    "info" => array(
     "name" => "$nombre", 
     "main" => "$descripcion" 
    ) 
); 

echo json_encode($arr); 

?> 

ich weiß, wie das Format mit statischen Informationen in php Array zu machen, aber ich weiß nicht, wie es zu machen mit die form daten, hier ist, wie ich es mit statischen info mit php arrays machen:

<?php 
$arr = array(
    "info" => array(
     "name" => "The Quiz Header", 
     "main" => "The Quiz Description Text"), 
    "questions" =>array(
     array(
      "q" => "The Question?", 

      "a" =>array(
     array(
     "option" => "an incorrect answer", 
     "correct" => "false"), 
     array(
     "option" => "a correct answer", 
     "correct" => "true"), 
     array(
     "option" => "an incorrect answer", 
     "correct" => "false"),), 

    "correct" => "The Correct Response Message", 

    "incorrect" => "The Incorrect Response Message", 

"select_any" => false, 

"force_checkbox" => false), 
    ) 
); 

echo json_encode($arr); 
?> 

Answer 1

Sieht aus wie die Werte sind nicht korrekt in PHP gefüllt. Verwenden Sie in Ihrem PHP-Code die folgenden Werte, um Werte zu arr zuzuweisen:

$arr = array(
    "info" => array(
    "name" => $nombre, 
    "main" => $descripcion 
) 
);
