I am using something like these arguments to order the archive loop, to order posts by a custom field.
$args = array(
'category_name' => $filter_cat,
'posts_per_page' => -1,
'meta_key' => 'year_start',
'orderby' => array( 'meta_value_num' => 'DESC', 'title' => 'ASC' )
);
On single.php
, how can I add a link to the next post and previous post in the same order as the main query above?
I want to have the possibility to skip from one post to another through all posts (not in one category).
