it simple, add condition above search code , put code inside condition. please check below code

used isset () in condition determine if variable set , not null , !empty()

if(isset($_post['search_code']) && !empty($_post['search_code'])) {     // code goes here      $search_code = $_post['search_code'];     global $wpdb;     $helloworld_id = $wpdb->get_var("select s_image search_code s_code = $search_code");     if (empty($helloworld_id)) {          echo '<div class="no_results">no results found</div>';      }else { ?>         <img src="http://igtlaboratories.com/wp-content/uploads/images/<?php echo $helloworld_id; ?>"style="width:200px;height: auto;">     <?php } }
