I have a walker to display terms of a taxonomy (see post here). It's a hierarchical list that is 3 levels deep:
Taxonomy
terms (number of posts incl. all sub levels)
1.1. subterms (number of posts incl. subsubterms 1 & 2)
1.1.1. subsubterms (number of posts)
- display post with Category "Subsubterms"
1.1.2 subsubterms (number of posts)
- display post with Category "Subsubterms"
The terms display fine, but the posts on subsubterm-level do not display. The following code only displays post from the "Uncategorized" category.
add_filter( 'XYZ_index', 'return_XYZ_index' );
function return_XYZ_index()
{
$taxonomies = array(
'XYZ'
);
$args = array(
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => false,
'fields' => 'all',
'parent' => 0,
'hierarchical' => true,
'child_of' => 0,
'pad_counts' => false,
'cache_domain' => 'core'
);
$terms = get_terms($taxonomies, $args);
$return .= '<ul>';
foreach ( $terms as $term ) {
$subterms = get_terms($taxonomies, array(
'parent' => $term->term_id,
'hide_empty' => false
));
//count posts in terms plus subterms
$count = 0;
$countargs = array(
'child_of' => $term->term_ID,
);
$tax_terms = get_terms($taxonomies,$countargs);
foreach ($tax_terms as $tax_term) {
$count +=$tax_term->count;
}
// return terms
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="post-count">' . $count . '</span><span class="cat-description">%3$s</span>',
$term->term_id,
$term->name,
$term->description
);
//count posts in subterm
$countsub = 0;
$countsubargs = array(
'child_of' => $subterm->term_id,
);
$tax_term_subs = get_terms($taxonomies, $countsubargs);
foreach ($tax_term_subs as $tax_term_sub) {
$countsub +=$tax_term_sub->count;
}
$return .= '<ul>';
foreach ( $subterms as $subterm ) {
$subsubterms = get_terms($taxonomies, array(
'parent' => $subterm->term_id,
'hide_empty' => false
));
// return subterms
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="post-count">' . $countsub . '</span><span class="cat-description">%3$s</span>',
$subterm->term_id,
$subterm->name,
$subterm->description
);
$return .= '<ul>';
foreach ( $subsubterms as $subsubterm ) {
// return subsubterms
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="post-count">%3$s</span><span class="cat-description">%4$s</span>',
$subsubterm->term_id,
$subsubterm->name,
$subsubterm->count,
$subsubterm->description
);
// return posts (**EDITED CODE**)
$postargs = array(
'tax_query' => array(
array(
'taxonomy' =>'XYZ,
'field' => 'id',
'terms' => $subsubterm->term_id
)
)
);
$post_query = new WP_Query( $args );
if ( $post_query->have_posts() ) :
$return .= '<ul>';
while ( $post_query->have_posts() ) : $post_query->the_post();
$return .= '<li><a class="link" href="' . get_permalink() . '">' . get_the_title() . '</a></li>' . "\n";
endwhile;
$return .= '</ul>';
wp_reset_postdata();
else:
endif;
$return .= '</li>'; //end subsubterms li
}
$return .= '</ul>'; //end subsubterms ul
$return .= '</li>'; //end subterms li
}
$return .= '</ul>'; //end subterms ul
$return .= '</li>'; //end terms li
} //end foreach term
$return .= '</ul>';
return $return;
}
I'm not sure if this part is even possible:
'term' => $subsubterm->term_id
Thanks!
