Php 在最后一行插入值

如上图所示，我的

stock\u transfer

表中有两个条目。 作为一个例子，我将插入两个不同的值来向您显示它正在工作。（产品1的5只股票和产品2的10只股票）

现在，当我尝试在

产品1

上插入请求的剩余库存，并离开

产品2

时，它将成功。

问题来了。当我尝试在我的

产品2

上插入值（290只股票）时，它将在

产品1

表中插入值。 有人能帮我吗？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：

我认为问题在于你输入的名字。您已将数组指定为输入的名称。尝试使用产品id使其唯一。
请参见：

  <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>


问题就在眼前

<?php if (!$remainingStocks == 0){ ?>
        <input type="number" name="qtyBuy[]" id="<?php echo "qtyBuy" . $b++; ?>" min="1" max="<?php echo $remainingStocks;?>">
        <?php } else{ ?>
          <i class="glyphicon glyphicon-check"></i> Completed
        <?php } ?>


对于安全问题，我建议您使用ajax，每次只提交一行的数量输入：

<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>Description</th>
    <th>Sell Price</th>
    <th>Expiry Date</th>
    <th>Instock</th>
    <th>Stocks Requested Remaining</th>
    <th>Stocks Transferred</th>
    <th>Quantity to Transfer</th>
  </tr>
</thead>
<tbody>

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

  while ($row = mysqli_fetch_array($getReqE)) {
    $transfer_id = $row['transfer_id'];
    $transfer_number = $row['transfer_number'];
    $transfer_status = $row['transfer_status'];
    $transfer_frombranch = $row['transfer_frombranch'];
    $transfer_tobranch = $row['transfer_tobranch'];

    $transfer_date = $row['transfer_date'];
    $stocks_transferred = $row['stocks_transferred'];

    $remainingStocks = $transfer_quantity - $stocks_transferred;

    $product_id = $row['product_id'];
    $product_name = $row['product_name'];
    $product_price = $row['sell_price'];

echo“UPDATE stock\u transfer SET stocks\u transfer=stocks\u transfer+$value，其中transfer\u id=$cartProd\u transid”
并查看您是否获得了产品的正确
id
？对于这两种情况，@BarneyStinson
更新库存转移集库存转移=库存转移+10，其中转移id=2
它第二次给了我正确的
id
。请将这两个案例都回显并粘贴到这里。我不知道你的更新查询是怎么做的properly@BarneyStinson
更新库存转移集库存转移=库存转移+300，其中转移id=1这是在完成对
产品1
@BarneyStinson
的请求后，第一次在
产品2
上插入值，其中transfer\u id=1
是我的
产品2
的查询结果，你能给我举个例子吗？
