有什么方法可以存储表中使用的按钮的ID？

Question

<?php
     while($row = mysqli_fetch_array($results)){
?>
  <tbody>
    <tr>
      <td> <?php echo $row['Product_ID'] ?></td>
      <td> <?php echo $row['Product_Name'] ?></td>
      <td> <?php echo $row['Product_Price'] ?></td>
      <td> <?php echo $row['Product_Stock'] ?></td>
      <td> <button type="submit" name="add" id="<?php $row['Product_ID'] ?>" onclick="func(<?php $row['Product_ID'] ?>)"> Add </button></td>    
    </tr>

<?php } ?>`

<script type="text/javascript" method="post">
    function func(id){
        window.alert(id); 
    };
 </script>

Is there a way I could store id of my button named add? I've to store multiple product ids and use them in a receipt that would be generated using product ids. the method of the form is POST but I don't know how to get the id

Answer 1

Replace this

 func(<?php $row['Product_ID'] ?>)

With This

 func(<?php echo $row['Product_ID']; ?>)
