New option to swap next and previous on single post

Hi all,

I was looking for a solution to swap the next and previous navigation buttons on a single post. To be clear, if I have a post category with 10 posts and open the category listing page, and then click on the first item (newest post/portfolio entry) in the list. When I view the first item, I will have an arrow on the left to navigate to the next post, which is the newest post after the one I am currently viewing. This is by default. I want the arrow to be on the right.

I searched the forums for a solution and found this: https://kriesi.at/support/topic/blog-post-previous-and-next-arrows/, which is closed to comments. While this solution worked and still works, the thread is old, so it’s a little outdated and there’s a better option in the current version of Enfold (v4.0.5). So I thought I would share it in case it’s useful to someone else out there:

Create a child theme if you haven’t already, and add the following code to the functions.php file in your child theme:

if (!function_exists('swap_single_post_next_and_previous_mod')) {
	add_filter( 'avia_post_nav_entries', 'swap_single_post_next_and_previous_mod' );
	/**
	 * Swap the next and previous navigation on single posts
	 *
	 * @param array $entries
	 *
	 * @return array
	 */
	function swap_single_post_next_and_previous_mod( $entries ) {
		if ( ! isset( $entries['prev'], $entries['next'] ) ) {
			return $entries;
		}

		$temp_prev = $entries['prev'];
		$entries['prev'] = $entries['next'];
		$entries['next'] = $temp_prev;

		return $entries;
	}
}

If you wanted to, you could also pass the $settings array to the function via the filter, and then only apply this to certain taxonomies or if certain other conditions are met, e.g.

if (!function_exists('swap_single_post_next_and_previous_mod')) {
	add_filter( 'avia_post_nav_entries', 'swap_single_post_next_and_previous_mod', 10, 2);
	/**
	 * Swap the next and previous navigation on single posts
	 *
	 * @param array $entries
	 * @param array $settings
	 *
	 * @return array
	 */
	function swap_single_post_next_and_previous_mod( $entries, $settings ) {
		if ( ! isset( $entries['prev'], $entries['next'] ) || $settings['taxonomy'] != 'my-category') {
			return $entries;
		}

		$temp_prev = $entries['prev'];
		$entries['prev'] = $entries['next'];
		$entries['next'] = $temp_prev;

		return $entries;
	}
}
