如何从嵌套表单中收集数据数组

嗨，我正试图使用javascript让管理员输入产品的尺寸、袋子数量和纸箱数量。由于我不能使用嵌套表单，所以我在表单中使用javascript。我可以使用javascript实现它，但无法收集文本框中输入的所有数据。仅显示第一个条目。

Php显示输入的数据

 $_SESSION['myInputs_all'][]=array($_POST["myInputs_d"],$_POST["myInputs_d1"],$_POST["myInputs_bags"],$_POST["myInputs_carton"]);
 print_r($_SESSION['myInputs_all']);
foreach ( $_SESSION['myInputs_all'] as $eachInput) 
{
     echo $eachInput . "<br>";
}

HTML

            <tr>
                <th>Size D(mm)</th>
                <th>Size D1(mm)</th>
                <th>No of Bags</th>
                <th>No of Carton</th>
                </tr>   
               <div id="dynamicInput">

         <tr><td> Entry 1</td></tr>
         <tr>
          <td><input type="text" name="myInputs_d" size='5'>
          <input type="text" name="myInputs_d1" size='5'>
          <input type="text" name="myInputs_bags" size='5'>
          <input type="text" name="myInputs_carton" size='5'></td>
         </tr>
     </div>
     <tr>
     <td>
     <input type="button" value="Add another text input"  name="myInputs[]" onClick="addInput('dynamicInput');">
                                                         </td>  
                                                        </tr>

javascript

<script>
var counter = 1;
var limit = 10;
function addInput(divName){
     if (counter == limit)  {
          alert("You have reached the limit of adding " + counter + " inputs");
     }
     else {
          var newdiv = document.createElement('div');
          newdiv.innerHTML = "Entry " + (counter + 1) + " <input type='text' name='myInputs_d[]' size='5'><input type='text' name='myInputs_d1[]' size='5'><input type='text' name='myInputs_bags[]' size='5'><input type='text' name='myInputs_carton[]' size='5'>";
          document.getElementById(divName).appendChild(newdiv);
          counter++;
     }
}
</script>

当我打印_r（$_SESSION[myInputs_all]）时，它显示

Array ( [0] => Array ( [0] => ujkopl [1] => jl[ [2] => uj [3] => juy ) ) Array
