try this!it checks if special offers set before echoing out content. hope that's looking for.

<?php  global $post;  $args = array(    'posts_per_page' => 4 , 'post_type' => 'gd_arts',);  $lastposts = get_posts( $args );  foreach ( $lastposts $post ) {?> <?php if(strlen ($post->geodir_special_offers) > 5){ ?> <h2><a href="<?php the_permalink(); ?>"> <?php the_title(); ?> </a></h2>  <?php if ( has_post_thumbnail() ) {              the_post_thumbnail(array(486,226));         }       } } wp_reset_postdata();  ?>
