Ok i realized i asked you a similar question before and this is how far i have come now
//Kundcase show links instead of content
add_action( 'wpsp_before_content','wpsp_add_custom_meta' );
function wpsp_add_custom_meta()
{
$meta = get_post_meta( get_the_ID(), 'kundcase_site_url', true );
if ( isset( $meta ) && '' !== $meta )
echo '<a class="button" href="'.$meta.'">Besök sidan</a>';
}How can i fetch and show post permalink beside this link?
