Add Previous/Next pagination to single posts within a category. If there are no adjacent posts, don't display anything.

prev_next_page.php

<? php //remove this line

// Adding pagination before and after post entry in Genesis Framework
add_action( 'genesis_before_entry', 'cd_prev_next_posts_nav' );
add_action( 'genesis_after_entry', 'cd_prev_next_posts_nav' );

// Add Prev/Next post navigation within a single category
function cd_prev_next_posts_nav() {

	// Check to see if there are previous and next posts
	$previous = get_adjacent_post( true, '', true );
	$next = get_adjacent_post( true, '', false );

	//bail if we're not on a single post with a previous or next post available
	if ( ! is_single() || ( empty( $next ) || empty( $previous ) ) ) {
		return;
	}

	echo '<div class="archive-pagination">';

	// build links to prev/next post in same category
	$prev_link = previous_post_link( '<div class="pagination-previous alignleft">%link</div>', '&laquo; Previous Post', TRUE );
	$next_link = next_post_link( '<div class="pagination-next alignright">%link</div>', 'Next Post &raquo;', TRUE );

	echo '</div>';
}

Thanks for this. Wondering how you would change the code if you wanted to add pagination on a single post but not limit it to within a category?

Could you add simple pagination that would just go to the previous/next post?
