I have several portfolio sections at my site: 4 pages, each showing another portfolio category.
When I'm on a single portfolio item, then I have the navigation on top of it:
<-- previous entry
--> next entry
The code for this is in single-portfolio.php:
<?php previous_post_link('<span class="previous_post_link">%link </span>'.__('(previous entry)','avia_framework')); ?>
<?php next_post_link('<span class="next_post_link">'.__('(next entry)','avia_framework').' %link</span>'); ?>
My problem is, these links "next" and "previous" make no difference, in which "portfolio category" I am at this moment:
they navigate through all portfolio categories.
That means, for example I am currently viewing a single portfolio item in category "acryl", and the "next" link on top of it leads me to an item from category "oil", depending on what I have posted after this item.
But I would like, that the "next" and "previous" navigation on top of this single portfolio items remains in ONE category. So I would like to change this code to something like this:
"show the next and previous link only to posts within this category from which this portfolio post is, that you are seeing here"
How can I change the code mentioned above please?
