PROBLÈME: PHP strip_tags & multi-dimensional array form parameter

Question

Je rencontre des problèmes pour supprimer les balises des entrées textuelles récupérées dans mon formulaire afin de faire quelque chose avec elles dans checkout.php. L'entrée est stockée dans un multi-dimensional array.

Voilà ma forme:

echo '<form name="choose" action="checkout.php" method="post" onsubmit="return validate_second_form(this);">'; 

     echo '<input type="hidden" name="hidden_value" value="'.$no_guests.'" />'; 

     if($no_guests >= 1){ 

      echo '<div class="volunteer">'; 
       echo '<fieldset>'; 
        echo '<legend>Volunteer:</legend>'; 
         echo '<label>Table:</label>'; 
         echo '<select name="volunteer_table">'; 
          foreach($tables as $t){ 
            echo '<option>'.$t.'</option>'; 
           } 
         echo '</select><br><br>'; 
         echo '<label>Seat number:</label>'; 
         echo '<select name="volunteer_seat">'; 
          foreach($seats as $seat){ 
            echo '<option>'.$seat.'</option>'; 
           } 
         echo '</select><br><br>'; 
         //echo '<br>'; 
       echo '</fieldset>'; 
      echo '</div>'; 

      for($i=0;$i<$no_guests;$i++){ 
       $guest = "guest_".$i; 
       echo '<div class="'.$guest.'">'; 
        echo '<fieldset>'; 
         echo '<legend>Guest '.$i.':</legend>'; 
          echo '<label>First Name:</label>'; 
          echo '<input type="text" name="guest['.$i.']['.$first_name.']" id="fn'.$i.'">'; 
          echo '<label>Surname:</label>'; 
          echo '<input type="text" name="guest['.$i.']['.$surname.']" id="surname'.$i.'"><br><br>'; 

          echo '<label>Date of Birth:</label> <br>'; 
          echo '<label>Day:</label>'; 
          echo '<select name="guest['.$i.'][dob_day]">'; 
           for($j=1;$j<32;$j++){ 
            echo"<option value='$j'>$j</option>"; 
           } 
          echo '</select>'; 

          echo '<label>Month:</label>'; 
          echo '<select name="guest['.$i.'][dob_month]">'; 
           for($j=0;$j<sizeof($month);$j++){ 
            $value = ($j + 1); 
            echo"<option value='$value'>$month[$j]</option>"; 
           } 
          echo '</select>'; 

          echo '<label>Year:</label>'; 
          echo '<select name="guest['.$i.'][dob_year]">'; 
           for($j=1900;$j<$year_limit;$j++){ 
            echo"<option value='$j'>$j</option>"; 
           } 
          echo '</select> <br><br>'; 

          echo '<label>Sex:</label>'; 
          echo '<select name="guest['.$i.']['.$sex.']">'; 
           echo '<option>Female</option>'; 
           echo '<option>Male</option>'; 
          echo '</select><br><br>'; 

          echo '<label>Table:</label>'; 
          echo '<select name="guest['.$i.']['.$table.']">'; 
           foreach($tables as $t){ 
            echo '<option>'.$t.'</option>'; 
           } 

          echo '</select><br><br>'; 
          echo '<label>Seat number:</label>'; 
          echo '<select name="guest['.$i.']['.$seat_no.']">'; 
           foreach($seats as $seat){ 
            echo '<option>'.$seat.'</option>'; 
           } 
          echo '</select><br><br>'; 
          //echo '<br>'; 
        echo '</fieldset>'; 
       echo '</div>'; 
      } 
     } 
     else{ 
      echo '<div id="volunteer">'; 
       echo '<fieldset>'; 
        echo '<legend>Volunteer:</legend>'; 
         echo '<label>Table:</label>'; 
         echo '<select name="volunteer['.$table.']">'; 
          foreach($tables as $t){ 
            echo '<option>'.$t.'</option>'; 
           } 
         echo '</select><br><br>'; 
         echo '<label>Seat number:</label>'; 
         echo '<select name="volunteer['.$seat_no.']">'; 
          foreach($seats as $seat){ 
            echo '<option>'.$seat.'</option>'; 
           } 
         echo '</select><br><br>'; 
         //echo '<br>'; 
       echo '</fieldset>'; 
      echo '</div>'; 
     } 
     echo '<input type="submit" value="Submit form">'; 
    echo '</form>'; 

est ici checkout.php:

if(isset($_POST['guest'])){ 
foreach($_POST['guest'] as $guest){ 
    $guest['first_name'] = strip_tags($guest['first_name']); 
    $guest['surname'] = strip_tags($guest['surname']); 
} 
//$_SESSION['guest'] = $guests; 
}

Vous avez besoin d'un & pour permettre l'édition de l'objet.

foreach ($_POST['guest'] as &$guest)
