Value inserting on last row - php

Question

Shown in the image above, I have two entries on my stock_transfer table.
As an example, I will insert two different values to show you that it's working. (5 stocks on Product 1 and 10 stocks on Product 2)
Now, when I try to insert the stocks requested remaining on Product 1 and leave the Product 2, it will be successful.
Here comes the problem. When I try to insert value (290 stocks) on my Product 2, it will insert the value in the Product 1 table.
Can anyone help me with this? Here's my query code:
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);
Here's is my code:
<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>

$getReq = "SELECT * FROM stock_transfer INNER JOIN td_products ON stock_transfer.transfer_product_id = td_products.product_id WHERE stock_transfer.transfer_number = $tid AND stock_transfer.transfer_tobranch = '$capitalPrefix';";
$getReqE = mysqli_query($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'];

Here's my schema:

Answer 1

See this:
<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>

Answer 2

for security issues, I advise you to use ajax and submit just the qty input for one row each time:
<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>

$getReq = "SELECT * FROM stock_transfer INNER JOIN td_products ON stock_transfer.transfer_product_id = td_products.product_id WHERE stock_transfer.transfer_number = $tid AND stock_transfer.transfer_tobranch = '$capitalPrefix';";
$getReqE = mysqli_query($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_product_id = $row['transfer_product_id'];
$transfer_quantity = $row['transfer_quantity'];
$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'];
$description = $row['description'];
$quantity = $row['quantity'];
$expiry_date = $row['expiry_date'];
echo $transfer_id;
?>
<tr>
<td class="text-center"><?php echo $product_id; ?>
</td>
<td><?php echo $product_name; ?>
</td>
<td><?php echo $description; ?>
</td>
<td>₱ <?php echo number_format($product_price, 2); ?></td>

Answer 3

The problem was on the
<?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 } ?>

Answer 4

I think the problem is with your input names. You have assigned arrays as names of your inputs. Try to make them unique using the product id.
