php - 在最后一行插入值

Question

如上图所示，我的 stock_transfer 表中有两个条目。 作为示例，我将插入两个不同的值来向您展示它的工作原理。 (产品 1 有 5 只股票，产品 2 有 10 只股票)

现在，当我尝试插入 Product 1 上剩余的请求库存并保留 Product 2 时，它将成功。

问题来了。当我尝试在我的 Product 2 上插入值(290 支股票)时，它会将值插入到 Product 1 表中。 谁能帮我这个？这是我的查询代码:

 if (isset($_POST['addCart']) && $_POST['addCart']=="Confirm Stock Transfer") {
 foreach($_POST['qtyBuy'] as $index=>$value){
 if($value > 0){

  $cartProd_id = $_POST['product_id'][$index];
  $cartProd_name = $_POST['product_name'][$index];
  $cartProd_date = $_POST['product_exp'][$index];
  $cartProd_desc = $_POST['product_desc'][$index];
  $cartProd_transid = $_POST['transfer_id'][$index];

  //Update stock_transfer requests
  $update_stock = "UPDATE stock_transfer SET stocks_transferred = stocks_transferred + $value WHERE transfer_id = $cartProd_transid;";
  $update_stockE = mysqli_query($connection, $update_stock);

这是我的代码:

<table class="table table-striped table-bordered table-hover results table-fixed table-condensed" id="example">
    <thead>
      <tr>
        <th>#</th>
        <th>Product Name</th>

        <th>Instock</th>
        <th>Stocks Requested Remaining</th>
        <th>Stocks Transferred</th>
        <th>Quantity to Transfer</th>
      </tr>
    </thead>

      $getReqE = mysqli_query($connection, $getReq);

      while ($row = mysqli_fetch_array($getReqE)) {
        $transfer_id = $row['transfer_id'];

这是我的架构:

Answer 1

看这个:

  <td>
     <input type="number" name="qtyBuy[]" id="<?php echo "qtyBuy" . $b++; ?>" min="1" max="<?php echo $remainingStocks;?>" <?php echo ($remainingStocks == 0') ? 'Disabled=true' : '';?> value="0">
   </td>
