I'm trying to display only those posts which are under the same category of the post which I have clicked as related posts. My custom taxonomy are like this :
Fsc year 1 => Biology => Bio chapter 1 . Now the problem is when I click a post from category bio chapter 1 all the posts in biology and bio chapter 1 display on the page that is the code that I found on google:
<?php
// get the custom post type's taxonomy terms
$custom_taxterms = wp_get_object_terms( $post->ID, 'category', array('fields' => 'slugs') );
$args = array(
'post_type' => 'subject',
'post_status' => 'publish',
'posts_per_page' => -1, // you may edit this number
'orderby' => 'rand',
'post__not_in' => array ( $post->ID ),
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => $custom_taxterms
)
)
);
$related_items = new WP_Query( $args );
// loop over query
if ( $related_items->have_posts() ) : ?>
<li class="widget widget_categories">
<h3 class="widget-title">Similar Posts</h3>
<ul>
<?php while ( $related_items->have_posts() ) : $related_items->the_post(); ?>
<li><a href="<?php the_permalink(); ?>"><?php the_excerpt(); ?></a></li>
<li><a href="<?php the_permalink(); ?>"><?php the_content(); ?></a></li>
<?php endwhile; ?>
</ul>
</li>
<?php endif;
// Reset Post Data
wp_reset_postdata();
?>
I want to display only bio chapter 1 posts as related post not the parent taxonomy's post in these related posts or if I click post from biology taxonomy only posts from biology show not posts from bio chapter 1 category. Can you please help me how I can do this I'm new to WordPress theme development I'll be very thankful to you.
