[Plugin: Custom Field Template] display function or…?

hi just wonder there is any function or something similar to display output titles only when fields are filled out

atm got this code in my single_post
<strong style="color:#0099cc;">date</strong> <?php getCustomField('date'); ?> | <strong style="color:#0099cc;">price</strong> <?php getCustomField('price'); ?>

but as u see titles are showing up each post
