Conditional output

What would be the best practices to output some blocks only if the custom field (that I want to output within a HTML block) is not empty?

Example:

<div class="content-col content-col-4 last">
 <div class="productprice"><?php echo CFS()->get('productprice'); ?></div>
 <p class="priceoption"><?php echo CFS()->get('priceoption'); ?></p>
 <br />
  <a class="button align-right" href="<?php echo CFS()->get('order_url'); ?>"><?php echo CFS()->get('btn_text'); ?></a><br />
 </div>

If productprice is empty the whole div-block should not be outputted.

So I guess, I could do something like

<?php
if (!empty(CFS()->get('productprice'))) {
?>
      <div class="content-col content-col-4 last">
        <div class="productprice"><?php echo CFS()->get('productprice'); ?></div>
        <p class="priceoption"><?php echo CFS()->get('priceoption'); ?></p>
        <br />
        <a class="button align-right" href="<?php echo CFS()->get('order_url'); ?>"><?php echo CFS()->get('btn_text'); ?></a><br />
      </div> <!-- .second-col -->
<?php
}
?>

But would this considered the right way to do it?
