I have a custom post type and used get_next_post() and get_previous_post() to create a simple pagination. However i need to create a pagination loop (if that is the correct term). If i'm on the first post i need to browse back to the last post and if i'm on the last post i need to browse to the first post. Is there a simple way to do this that i haven't seen but Google, this site and the codex has not been very helpfull :/
The current code i have is. I've tried to use wp_list_pages and other functions but with little luck.
$next_post = get_next_post();
$prev_post = get_previous_post();
$nav = array(
"next_post" => array(
"url" => get_permalink($next_post->ID),
"id" => $next_post->ID,
"titill" => get_field("vinstri_titill", $next_post->ID)." - ".get_field("vinstri_undirtitill", $next_post->ID)
),
"prev_post" => array(
"url" => get_permalink($prev_post->ID),
"id" => $prev_post->ID,
"titill" => get_field("vinstri_titill", $prev_post->ID)." - ".get_field("vinstri_undirtitill", $prev_post->ID)
),
);

Reset to default 1Here is one idea for the previous post circle:
$next_post = get_next_post();
$prev_post = get_previous_post_circle();
where we have defined this function:
function get_previous_post_circle($in_same_cat = false, $excluded_categories = ''){
$prev_post = get_previous_post($in_same_cat,$excluded_categories);
if($prev_post){
return $prev_post;
}else{
add_filter('get_previous_post_where','custom_get_previous_post_where');
$prev_post = get_previous_post($in_same_cat,$excluded_categories);
remove_filter('get_previous_post_where','custom_get_previous_post_where');
if($prev_post){
return $prev_post;
}else{
return '';
}
}
}
and the filter function to remove the specific date comparison:
function custom_get_previous_post_where($where){
$where=" WHERE ".implode(" AND ",array_slice(explode("AND",$where),1));
return $where;
}
The aim is to emulate the get_previous_post() function with the same input parameters, but you could of course play with get_post() in your code instead to create the closed loop.
My solution if next is not empty give me loop, but only the first with permalink:
<?php
$next_post = get_previous_post();
if (!empty( $next_post )): ?>
<a href="<?php echo esc_url( get_permalink( $next_post->ID ) ); ?>"><?php echo esc_attr( $next_post->post_title ); ?></a>
<?php else: ?>
<?php $args = array(
'post_type'=> 'post',
'orderby' => 'ID',
'post_status' => 'publish',
'order' => 'ASC',
'posts_per_page' => 1 // this will retrive all the post that is published
);
$result = new WP_Query( $args );
if ( $result-> have_posts() ) : ?>
<?php while ( $result->have_posts() ) : $result->the_post(); ?>
<?php the_permalink(); ?>
<?php endwhile; ?>
<?php endif; wp_reset_postdata(); endif; ?>
