Show Last Post Excerpt On Any WordPress Page

So there is a little code that you can use to query the posts then show the last post on a page. in this particular code we are ordering by date and grabbing the last post that was made according to the date. The following code will grab:

1. The Permalink
2. The title
3. The Excerpt
4. The Featured image

 

<?php $the_query = new WP_Query( 'posts_per_page=1&order=DESC&orderby=date' ); ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>

<div class="entry">
 <a href="<?php echo get_post_permalink();?>">
<h3><?php the_title(); ?></h3>

 <?php $feat_image = wp_get_attachment_url( get_post_thumbnail_id($post->ID) ); 
 echo '<img src="'.$feat_image.'"/>'; ?>
 <?php the_excerpt(); ?></a>
  </div>

<?php endwhile; wp_reset_postdata(); ?>
