If you want to change the existing navigation in Atahualpa Theme of your WordPress website that navigate all post based on the order of the general Post ID no matter which category you choose, become the smarter technique which will navigate based on the current category that selected by user, then this following modification is for you! As we know, Atahualpa theme has provided the previous/next link when we display the certain post in the top of the post page. Unfortunately, by default, when we choose the certain category, then we navigate through that navigation post link, it will avoid the selected category. Now, after you implement this following modification, you will be able to navigate only through the posts that located in the certain category that you have choosen. Isn’t smarter, huh?

1. Download the Smarter Navigation plugin.
2. Upload this plugin to your /wp-content/plugins/ and then extract it.
3. Activate this plugin from your wp-admin.
4. Open your /wp-content/themes/{youratahualpaname}/functions/bfa_next_previous_links.php file, and find this code:

   137 138

   previous_post_link($bfa_ata['single_next_prev_older']) : next_post_link($bfa_ata['single_next_prev_newer']);

   then replace with this following code:

   137 138

   previous_post_smart($bfa_ata['single_next_prev_older']) : // previous_post_link replaced by previous_post_smart in order to navigate only in the current category using Smarter Navigation plugin, modified by Masino Sinaga, Januari 16, 2010 next_post_smart($bfa_ata['single_next_prev_newer']); // next_post_link replaced by next_post_smart in order to navigate only in the current category using Smarter Navigation plugin, modified by Masino Sinaga, Januari 16, 2010

   Find again this code:

   147 148

   next_post_link($bfa_ata['single_next_prev_newer']) : previous_post_link($bfa_ata['single_next_prev_older']);

   then replace with this following code:

   147 148

   next_post_smart($bfa_ata['single_next_prev_newer']) : // next_post_link replaced by next_post_smart in order to navigate only in the current category using Smarter Navigation plugin, modified by Masino Sinaga, Januari 16, 2010 previous_post_smart($bfa_ata['single_next_prev_older']); // previous_post_link replaced by previous_post_smart in order to navigate only in the current category using Smarter Navigation plugin, modified by Masino Sinaga, Januari 16, 2010

The conclusion: All you need to do is simply replace the link with smart in the previous_post_link and next_post_link function call in bfa_next_previous_links.php file belongs to Atahualpa theme. Afterwards, you can navigate through the posts only that located in the certain category you chose.
