I want to have a link to another page, with particular subject, How can I pass the id ?

            <td><a href='approve.php?id=".$sub->id."' role="button" class="btn">Add Topic</a></td>
        </tr>
        <?php endforeach;?>
    </tbody>
</table>

推荐答案

您仍然需要将其回显.

<?php foreach($subjects as $sub): ?>
    <tr>
    <td><?php echo $sub->subject ?></td>
    <td><a href="approve.php?id=<?php echo $sub->id ?>" role="button" class="btn">Add Topic</a></td>
    </tr>
<?php endforeach; ?>
