    <a  class="buttonside" href="vpa.php?pgid=<?php echo $row['page_id']; ?>">
     <?php echo $row['btn_text']?></p>
              </a>
                                  </div>

                                    </td>
                                </tr>

                            </table>

                            </td>
                          </tr>
                        </table>
                       <?php
                       }
                       ?>

this code is working fine but the link is on text, i want to put link on full button(background)

Thanks

To make the button 'linkable', you'll need to wrap the <a> tag around it.

However, you're going to need to change your HTML markup structure - you can't wrap an anchor around a table cell!
