Limit Next & Previous on Single Post page to same category

Hi, @iambeeblebrox,
If you use a child theme, you can modify the theme’s function to link posts from the same category using in_same_term parameter as described here:

I hope this helps. If it doesn’t work, please let us know again.

Thanks.

Hmmm. I cannot find any call to next_post_link in the theme files (I did a ‘grep -r’ for next_post_link).

Please add this code inside the child theme’s functions.php file:

function zakra_child_post_navigation() {
   the_post_navigation( array( 'in_same_term' => true, ) );
}
add_action( 'zakra_after_single_post_content', 'zakra_child_post_navigation', 10 );

Ah. This worked to some extend … after adding this code I get two ‘nav’ elements with the post-navigation class. The first one is the right one, the second one is the old version.

I have now managed to hide the last one using CSS, but there must be a better way. Maybe by doing a “remove_action”. Only thing is that the original action is only added after functions.php from my child_theme executes.

And …. I think I have found the best solution.

I just have to define zakra_post_navigation instead of zakra_child_post_navigation in my functions.php. I can then omit the add_action. I found that within the Zakra team the code checks whether this function exists and only then defines it.

So what I have now is this:

function zakra_post_navigation() {
   the_post_navigation( array( 'in_same_term' => true, ) );
}

Yes. That’ll also work. ??
