How can I check for a thumbnail in WordPress?

Question

How can I can I check if a post has a thumbnail and if does do something? If doesn't do something else. This is what I have:

 <?php if (has_post_thumbnail()) ?>

 <?php the_thumbnail(); ?>
 ?>

 <?php else ?>

 <?php the_permalink();?>

 <?php endif; ?>

Any help will be appreciate it.

You need to use the_post_thumbnail instead of the_thumbnail within the loop. This is how it should be formatted:

<?php if(have_posts()){
    while(have_posts()){
        the_post();
        if(has_post_thumbnail()){
            the_post_thumbnail();
        }
    }
}?>
