wordpress — Get posts if they had a thumbnail

Question

Who knows, how can i get only posts, what had a thumbnail picture? I didn't find anything in WP documentation. Please, help! Filters of get_posts() are not including thumbnail.

Answer 1

This should work:

<?php 
   $loop = new WP_Query( array('meta_key' => '_thumbnail_id', 'post_type' => 'post')); 
   while($loop->have_posts()) : $loop->the_post(); 
?>
<h2><?php the_title(); ?></h2>
<?php the_post_thumbnail(); ?>
<?php endwhile; ?>

That will return all posts that has a thumbnail (featured image) attached.

Answer 2

you can check the post have thumb or not using has_post_thumbnail( $post_id );

example :

<?php
while ( have_posts() ) : the_post();
if(has_post_thumbnail( the_ID )) {
 #code....
}
endwhile;
?>
