Question

尝试使用解决方案尝试了多个问题，但都没有解决我的问题。

此表单使用JQuery动态添加一组字段。问题是MySQL在提交时没有插入数据集。这是代码：

HTML：

<form action="new_purchase_order%20(1).php" method="post">
       Supplier
       <select name="supplier[]">
         <option value="">Select supplier...</option>
          <?php
            $get_supps = "select supplier_name from suppliers";
            $supplist = mysqli_query($db, $get_supps);
              //get suppliers available in the database
              while($row = mysqli_fetch_assoc($supplist)) {
          ?>
         <option value="<?php echo $row['supplierID'] ?>"><?php echo $row['supplier_name'] ?></option>
        <?php } ?>
      </select><br /><br />

      <select name="item[]">
         <option value="">Select item...</option>
          <?php
            $get_items = "select name from raw_materials";
            $itemlist = mysqli_query($db, $get_items);
            //get all raw materials available in the database
            while($row = mysqli_fetch_assoc($itemlist)) {
          ?>
          <option value="<?php echo $row['materialID'] ?>"><?php echo $row['name'] ?></option>
          <?php } ?>
       </select>
       <!--enter its unit price-->
       <input type="text" name="price[]" placeholder="Unit Price">
       <!--enter the qty of the item selected-->
       <input type="number" name="qty[]" min=1 placeholder="Qty" width="30px">
       <a href="javascript:void(0)" class="button addMore">ADD</a>

PHP：

<?php
include("session.php");

if (isset($_POST['submit'])) {
$supplier = $_POST['supplier'];
$item = $_POST['item'];
$qty = $_POST['qty'];
$price = $_POST['price'];

for ($i=0; $i < count($item); $i++) {
  $supplier[$i] = mysqli_real_escape_string($db, $supplier[$i]);
  $item[$i] = mysqli_real_escape_string($db, $item[$i]);
  $qty[$i] = mysqli_real_escape_string($db, $qty[$i]);
  $price[$i] = mysqli_real_escape_string($db, $price[$i]);

  if (count($item) >= 0 && count($item) <= 24) {
    mysqli_query($db, "insert into purchase_order_history values('', '{$item[$i]}', '{$qty[$i]}', '{$price[$i]}', '', '$supplier[$i]', 'Pending')");
    echo "Success";
  }
  else {
    echo "Error";
  }
}
}

?>

基本上它使用item，qty和price的数组。我的问题是尽管PHP没有错误，它根本不插入任何东西。查询是：

插入purchase_order_history值（''，'{$ item [$ i]}'，'{$ qty [$ i]}'，'{$ price [$ i]}'，''，'$供应商[$ i]'，'待定'）;

编辑：这是JQuery代码：

  <!-- jQuery library -->
  <script 
   src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <!-- Bootstrap js library -->
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"> 
  </script>

  <script type="text/javascript">
  $(document).ready(function(){
  //group add limit
  var maxGroup = 24;
  //add more fields group
  $(".addMore").click(function(){
      if($('body').find('.form').length < maxGroup){
          var fieldHTML = '<div 
  class="form">'+$(".formCopy").html()+'</div>';
          $('body').find('.form:last').after(fieldHTML);
      }else{
          alert('Only '+maxGroup+' items are allowed.');
      }
  });

  //remove fields group
  $("body").on("click",".remove",function(){
      $(this).parents(".form").remove();
  });
  });
  </script>

查询本身是否有错误？或者是导致问题的数组编码？
