I am working on a dynamic website. here is the code of a particular page. In this page there is a div section with class="col md-4". If the number of content panel in that division appears to 5 or 7 in that case I want only the last panel (i.e 5th and 7th) to be in full column (col-12). What should I do?

Answer 1

Since you are using col-md-4, 3 divs will be shown each row. So I think what you are looking for is a way to make the last div full width if its going to be alone in its row. In that case, you will need to make it col-md-12 on 4th (not 5th) and 7th and 10th records and so on. This is exactly what the following code does,

I think what you want to do is show the

    <?php
    if($_GET[id] == 0)
{
    $querysb=mysql_query("SELECT  * FROM services WHERE parentid !=0 order by parentid, cid ");
}
    else
{
    $querysb=mysql_query("SELECT  * FROM services WHERE parentid='".$_GET[id]."'");
}
$number_of_records = mysql_num_rows($querysb);
    $counter = 1;
    while($rowsb=mysql_fetch_assoc($querysb))
{
        if($val == '6' || $val =='10'){
            $classname= 'whitebg';
        }else{
            $classname= 'bg-blue co-white';
}
        //if($number_of_records %3 ==1 && $counter == $number_of_records)
        if(($number_of_records == 5 ||  $number_of_records == 7) && $counter == $number_of_records)
            $col_class = "col-md-12";
        else
            $col_class = "col-md-4";
 
    ?>
 
              <div class="<?php echo $col_class;?> mrgnBtm15">
                <div class="<?php echo $classname;?> padding30" style="min-height: 250px">
                 <h3 class="service-heading">
                    <?php echo $rowsb['cname'];?>
                  </h3>
                  <h4>
                    RS <?php echo $rowsb['price'];?><br>
                  </h4>
                  <div class="mrgnTop15 clearfix"></div>
 
                  <a  class="btn bg-orange co-white" href="<?php echo MYWEBSITE;?>servicedetail/<?php echo to_prety_url($rowsb['cname']).'-'.$rowsb['cid'];?>.html">
                      <font style="size:14px; color:#000; font-weight:bolder;font-family: "Open Sans";">Register</font></a>
 
                </div>
              </div>
    <?php
$counter++;
     } ?>
            </div>
          </div>
        </div>
