php - 从 json 返回多个值

Question

目前，我正在使用一个脚本，该脚本以 msg[0].box msg[1].box 等格式从 json 返回一个值。如果用户输入 2 个项目，那就可以了。但如果用户输入的内容不止于此，该怎么办？我的一个 friend 建议我查看 jquery every 函数来重新调整多个值，但由于我对 jquery 相当陌生，如果有人可以帮助我使用我的代码实现此目的，我将不胜感激。

我也很困惑为什么返回值时firebug中没有json选项卡，只有reposnse和html。这是正常的吗？请注意，输入值时使用 , 作为分隔符。

php代码

    $dept = mysql_real_escape_string($_POST['customerdept']);
    $company = mysql_real_escape_string($_POST['BA_customer']);
    $address = mysql_real_escape_string($_POST['customeraddress']);
    $service = mysql_real_escape_string($_POST['BA_service']);
    $box = mysql_real_escape_string($_POST['BA_box']);
    $date = DateTime::createFromFormat('d/m/Y', $_POST['BA_destdate']);
    $destdate = $date -> format('Y-m-d');
    $authorised = mysql_real_escape_string($_POST['BA_authorised']);
    $activity = 'New Intake';
    $submit = mysql_real_escape_string($_POST['submit']);
    $boxerrortext = 'You must enter a box for intake';

    $array = explode(',', $_POST['BA_box']);

        if (isset($_POST['submit']))   {
          foreach ($array as $box) {


          $form=array('dept'=>$dept,
                 'company'=>$company,
                 'address'=>$address,
                 'service'=>$service,
                 'box'=>$box,
                 'destroydate'=>$destdate,
                 'authorised'=>$authorised,
                 'submit'=>$submit);

          $result[]=$form;

   }  

          echo json_encode( $result );
   }

jquery代码

submitHandler: function()   {
                if ($("#BA_boxform").valid() === true)  { 
                var data = $("#BA_boxform").serialize();
                $.post('/sample/admin/requests/boxes/boxesadd.php', data, function(msg) {
                $("#BA_addbox").html("You have entered box(es): " + "<b>" + msg[0].box + "  " + msg[1].box + "</b><br /> You may now close this window.");
                //console.log(msg[0].box);
                $("#BA_boxform").get(0).reset();
                }, 'json');

         } else

         { 
           return; 
         }
        },
        success:    function(msg)   {
                //$("#BA_addbox").html("You have entered a box");
                //$("#BA_boxform").get(0).reset();
        }

关于如何使用$.each函数...

var html = "You have entered box(es): <b>"
$.each(msg, function(index, element) { 
    if(index > 0)
         html += " ";
    html += element.box;
});
html += "</b><br /> You may now close this window."
