我需要創(chuàng)建一個訂單表，其中有一個表格中每個產(chǎn)品的復(fù)選框，每個產(chǎn)品旁邊都有一個數(shù)量框。我需要處理已檢查的產(chǎn)品并使用已檢查的產(chǎn)品和輸入的數(shù)量更新訂單表。我不知道如何將產(chǎn)品復(fù)選框鏈接到數(shù)量字段。$sql="select * from tproducts";$result=mysqli_query($con, $sql) or die(mysqli_error($con));echo "<table>";echo "<tr>";echo "<th>Product Names</th>";echo "</tr>";if(mysqli_num_rows($result)>0){  echo "<form action=welcome1.php method=post>";  while ($row = mysqli_fetch_array($result))  {    echo "<tr>";    echo '<td><input type="checkbox" value="' . $row['intProductID'] . '" name="materialcode[]">' . $row['strProductName'] . "</td>";    echo "<td>Enter Quantity </td>";    echo "<td><input type='text' name='qty[]' value='qty' size=5></td>";      echo "</tr>";  } } echo "</table>";echo '<input type="submit" name="submit" value="submit" />';echo "</form>";echo "</html>";welcome1.php<?phpecho "materialcode<br>";print_r($_POST['materialcode']);echo "<br>";echo "qty<br>";print_r($_POST['qty']);?>
