restrict nav links in blog page-builder element to the same category

[brianfogel]

Hello I’m adding posts to the bottom of a page using the Blog page-builder element.  Can I can restrict the display of nav-previous and nav-next links in DIV class=”pagination-wrap blog-pagination” to posts that belong to the same category (or categories) as the current post?

For example, although a post belongs only to the “A” category there is a nav-next link to a post that belongs to the “C” category.  I want people to be able to navigate within this blog element only to posts sharing the same category.

Hi,

Having it hidden on particular posts would need advanced custom coding, with which we can’t help unfortunately. I suggest hiring a freelancer to custom code it.

Thanks very much for your answer.  I am a javascript and PHP coder.  Is there online info that could direct me to the appropriate locations in the codebase?  That would give me a head start?

You can do this quite easily actually, just edit single.php and change line 304-307:

<div class="pagination-wrap blog-pagination clearfix">
	<div class="nav-previous"><?php next_post_link('%link', __('<i class="icon-angle-left"></i> <span class="nav-text">%title</span>', 'swiftframework'), TRUE); ?></div>
	<div class="nav-next"><?php previous_post_link('%link', __('<span class="nav-text">%title</span><i class="icon-angle-right"></i>', 'swiftframework'), TRUE); ?></div>
</div>

Hope that helps.

Thanks, that was easy and it restricts navigation to posts in the same category.  However, this apparently works only if posts belong to a single category.  If any belong to multiple categories they don’t obey.  I guess there’s something more complicated going on with those.  Do you have any idea how to make this really, truly strict?

That’s why I was saying it requires advanced theme customizations.

You would need to custom code a meta field for your posts, where you could specify if the nav links should show up or not. Something similar to what we have for the post options; you could add an option with a dropdown per post, to choose yes/no for the nav links.

If you’re familiar with WordPress development, you can take a look at our options framework and eventually add your own option in there.

Cosmin, I am new to WordPress development but this is a good a time as any to get started.  Are you referring to the WordPress options framework or one created by swiftideas?

Hi Brian,

Our theme options are a hybrid of Options Framework, custom shortcodes, custom Page Builder code and custom meta boxes added to the WordPress admin pages.

You would need to tie a custom coded theme option together with a custom coded meta box that you would add to post edit screens.
