Getting the values of custom post fields

It is possible to get the custom post field value?

Yes use get_post_meta function.

If “in the WordPress Loop” use this code:

$result = get_post_meta($post->ID, 'customField', true);

If outside the Loop use this code:

global $wp_query;
$postid = $wp_query->post->ID;
echo get_post_meta($postid, 'customField', true);
