Question

i want to display my portfolio contents in fancybox. I could display the featured image but couldn't display text content. My codes which i used:

<div class="port-img fancybox" rel="gallery">
                                    <img src="<?php echo esc_url( $featured_img ); ?>" alt="Work"/><br/>
                                     <?php $postQuery->printText('general description-small'); ?>
                              </div>

And my full document is here.
