I'm trying to modify a old theme but im getting stuck on this code
$post_type = 'portfolio' == get_post_type() ? 'portfolio' : 'post';
if ( ! themify_check( "setting-{$post_type}_nav_disable" ) ) :
$in_same_cat = themify_check( "setting-{$post_type}_nav_same_cat" )? true: false;
$this_taxonomy = 'post' == get_post_type() ? 'category' : get_post_type() . '-category';
$previous = get_previous_post_link( '<span class="prev">%link</span>', '<span class="arrow">' . _x( '«', 'Previous entry link arrow','themify') . '</span> %title', $in_same_cat, '', $this_taxonomy );
$next = get_next_post_link( '<span class="next">%link</span>', '<span class="arrow">' . _x( '»', 'Next entry link arrow','themify') . '</span> %title', $in_same_cat, '', $this_taxonomy );
if ( ! empty( $previous ) || ! empty( $next ) ) : ?>
<div class="post-nav clearfix">
<?php echo $previous; ?>
<?php echo $next; ?>
</div>
<!-- /.post-nav -->
<?php endif; // empty previous or next
endif; // check setting nav disable
This part specifically. Currently it is listing all of my articles but I cant figure out how to list only category id 1 2 3
$this_taxonomy = 'post' == get_post_type() ? 'category' : get_post_type() . '-category';

Reset to default 1You are looking at the wrong line. $this_taxonomy is telling what taxonomy type (category, tag, custom tax, etc.) to look for, not what actual term in that taxonomy type.
That being said, you should look at $previous and $next. More specifically, get_previous_post_link() and get_next_post_link(). The fourth parameter is $excluded_terms which is currently empty.
The codex says you can supply an array or comma-separated list of term ids.
This would seem cumbersome to maintain because you would have to update that parameter each time a new term is added to your taxonomy.
But technically, if you have categories 1,2,3,4 and 5, then supplying $excluded_terms = '4,5'; to your previous and next function would exclude those terms from your list.
So, if you want a method that won't need updating each time a new category is added, I would try to do it by modifying the main query instead. Add this to your functions.php
add_action( 'pre_get_posts', 'my_allowed_cats' );
function my_allowed_cats( $query ){
$post_type = get_post_type();
if( $post_type == 'post' || $post_type == 'portfolio' ){
// Use category ids
$allowed_cats = array(
1,
2,
3,
);
$query->set( 'category__in', $allowed_cats );
}
}
This is untested, but it should work
