Wordpress - get_posts assigned to a specific custom taxonomy term, and not the term's children
In looking at the WP_Tax_Query class in /wp-includes/taxonomy.php, I found that there is a 'include_children' option which defaults to true. I modified my original get_posts() call with the following, and it works great:
$pages = get_posts(array(
'post_type' => 'page',
'numberposts' => -1,
'tax_query' => array(
array(
'taxonomy' => 'taxonomy-name',
'field' => 'term_id',
'terms' => 1, /// Where term_id of Term 1 is "1".
'include_children' => false
)
)
));
List of more query parameters: https://developer.wordpress.org/reference/classes/wp_query/#taxonomy-parameters
just came across this the other day:
$tax = 'music';
$oterm = 'pop';
$term = get_term_by('slug', $oterm, $tax);
$termChildren = get_term_children($term->term_id, $tax);
$wp_query = new WP_Query();
$wp_query->query(
array(
'posts_per_page' => '5',
'tax_query' => array(
array(
'taxonomy' => $tax,
'field' => 'slug',
'terms' => $oterm
),
array(
'taxonomy' => $tax,
'field' => 'id',
'terms' => $termChildren,
'operator' => 'NOT IN'
)
)
)
);

Here is complete code hope it helps. Thanks
<?php
$terms_array = array(
'taxonomy' => 'services', // you can change it according to your taxonomy
'parent' => 0 // If parent => 0 is passed, only top-level terms will be returned
);
$services_terms = get_terms($terms_array);
foreach($services_terms as $service): ?>
<h4><?php echo $service->name; ?></h4>
<?php
$post_args = array(
'posts_per_page' => -1,
'post_type' => 'service', // you can change it according to your custom post type
'tax_query' => array(
array(
'taxonomy' => 'services', // you can change it according to your taxonomy
'field' => 'term_id', // this can be 'term_id', 'slug' & 'name'
'terms' => $service->term_id,
)
)
);
$myposts = get_posts($post_args); ?>
<ul>
<?php foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach; // Term Post foreach ?>
</ul>
<?php wp_reset_postdata(); ?>
<?php endforeach; // End Term foreach; ?>
