如何从数据集（PHP）传递正确的ID？

Question

This is a part of index.php. This code is used to display the all the products in database.

 while($row = mysqli_fetch_array($result)) {?>     
      <form action="product.php?>" method="post">

           <tr class="info">
            <td align="center"><h3><?php echo $row['name'];?></h3></td>
          </tr>

          <tr class="success">
            <td align="center"><div class="grow pic"><img src="uploads/<?php echo $row['image'];?>"></div></td>
          </tr>

          <tr class="info">
            <td><?php echo substr($row['description'],0,75);?></td>
          </tr>

          <tr class="success">
            <td align="center"><input name="cart" type="submit" value="More Details"></td>
            </tr>

          <tr>
          <td></td>
          </tr>

      </form>
      <?php
      }
      ?>

There is a another page called product.php. When user click the "More details" button in index.php it will redirect to the product.php.

What I want to do is, I need to pass the correct product id for that page when user click the "more details" button. How to do it?

Answer 1

like the comments say, add a hidden input tag to your form:

<input name="id" type="hidden" value="<?=$row['id'];?>"/>

then in product.php, you can access it by:

$id = $_POST['id'];

that's it..
