                    if ($r=mysqli_num_rows($q)>0 )?>
                        <?php while ($r=mysqli_fetch_array($q)): ?>
                <tr>

                    <td>
                        <a class="label label-primary" data-toggle="modal"  data-target="#modal-id">View</a>    
                             <div class="modal fade" id="modal-id">
                                <div class="modal-dialog">
                                    <div class="modal-content">
                                        <div class="modal-header">
                                            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                                            <h4 class="modal-title">Full Record</h4>
                                        </div>
                                        <div class="modal-body">
                                        <h1>Ok</h1>
                                        </div>
                                        <div class="modal-footer">
                                            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                                        </div>
                                    </div>
                                </div>
                             </div>      
                    </td>
                </tr>
            <?php endwhile ?>
            </tbody>
            </table>

but i fetech some of columns of that data now i want to fetch the rest of the columns in the modal which created dynamically in other words i fetch half data in table columns and others data in table inside modal my problem is how to fetch the rest of column in modal parallel to the data means when someone trigger modal all the data of clicked id modal is fetched which is fetched already.
