Blogger has a simple post navigation, older & newer posts or prev & next posts, which displays all posts in a row.
<div class='blog-pager' id='blog-pager'>
<b:if cond='data:newerPageUrl'>
<span id='blog-pager-newer-link'>
<a class='blog-pager-newer-link' expr:href='data:newerPageUrl' expr:id='data:widget.instanceId + "_blog-pager-newer-link"' expr:title='data:newerPageTitle'>
<data:newerPageTitle/>
</a>
</span>
</b:if>
<b:if cond='data:olderPageUrl'>
<span id='blog-pager-older-link'>
<a class='blog-pager-older-link' expr:href='data:olderPageUrl' expr:id='data:widget.instanceId + "_blog-pager-older-link"' expr:title='data:olderPageTitle'>
<data:olderPageTitle/>
</a>
</span>
</b:if>
</div>
I need what this navigation display next and prev posts by labels, for example as related posts widget display only that posts, which belong to the categories of this post.
I found some scripts, but all of them not working. Does anybody know, how to resolve this problem?
