Here’s a growing collection of code snippets I find useful.

Enable the Post Thumbnail Feature

Post thumbnails were added in WordPress 2.9. Justin Tadlock has a great article about this. To enable the feature in your theme, simply add this code snippet to the functions.php file:

if ( function_exists( 'add_theme_support' ) ) {
	add_theme_support( 'post-thumbnails' );
}

To Use Post Thumbnails

<?php the_post_thumbnail( 'thumbnail' ); ?>
<?php the_post_thumbnail( 'medium' ); ?>
<?php the_post_thumbnail( 'full' ); ?>

Get the Post Name

This function is great if you need to style a certain element differently from page to page.

<div class="<?php echo $post->post_name; ?>">
</div>
