WordPress:分类术语的层次列表 [英] Wordpress: hierarchical list of taxonomy terms
问题描述
尽管听起来很简单,但我还是碰壁了:我想返回自定义帖子类型分类术语的层次列表.我得到的是术语和嵌套ul的第一层.但是子条款没有显示.有什么想法吗?
I am hitting a wall here, although it sounds pretty simple: I want to return a hierarchical list of custom post type taxonomy terms. What I get is the first level of terms and nested uls. But the sub terms are not showing. Any ideas?
代码如下:
function return_terms_index() {
$taxonomies = array(
'taxonomy_name',
);
$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 ) {
// return terms (working)
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$term->term_id,
$term->name,
$term->description
);
$subterms = get_terms( array(
'parent' => $term->term_id,
'hide_empty' => false
));
$return .= '<ul>';
foreach ( $subterms as $subterm ) {
//return sub terms (not working :( )
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$subterm->term_id,
$subterm->name,
$subterm->description
);
$return .= '</li>'; //end subterms li
}
$return .= '</ul>'; //end subterms ul
$return .= '</li>'; //end terms li
} //end foreach term
$return .= '</ul>';
return $return;
}
谢谢!
.这是输出.
<ul>
<li id="category-176">
1. <span class="post-count">0</span><span class="cat-description" style="display: none;">Description</span>
<ul id="subTerm-176" style="display: block;"></ul>
</li>
<li id="category-49">
2. <span class="post-count">0</span><span class="cat-description" style="display: none;">Langtitel/Beschreibung</span>
<ul id="subTerm-49" style="display: none;"></ul>
</li>
</ul>
现在,分类列表中返回了分类法. 但是我也想查询和显示第三级分类术语的帖子,而这段代码并不能解决问题.
taxonomies are returned in hierarchical list now, YAY! But I want to query and display posts of third level taxonomy terms as well and this bit of code doesn't do the trick.
$post_query = new WP_Query($taxonomies, array(
'term' => $subsubterm->term_id
)); ?>
<?php 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;
它必须是动态的,所以我不能通过名称/子句来指定一个术语.但这有可能吗?
It has to be dynamic, so I can't specify a term by name/slug. But is this even possible?
'term' => $subsubterm->term_id
再次感谢.
推荐答案
您错过了传递$ taxonomies的功能
You have missed to pass $taxonomies in
$subterms = get_terms($taxonomies, array(
'parent' => $term->term_id,
'hide_empty' => false
));
尝试以下代码
function return_terms_index() {
$taxonomies = array(
'taxonomy_name',
);
$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 ) {
// return terms (working)
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$term->term_id,
$term->name,
$term->description
);
$subterms = get_terms($taxonomies, array(
'parent' => $term->term_id,
'hide_empty' => false
));
$return .= '<ul>';
foreach ( $subterms as $subterm ) {
//return sub terms (not working :( )
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$subterm->term_id,
$subterm->name,
$subterm->description
);
$return .= '</li>'; //end subterms li
}
$return .= '</ul>'; //end subterms ul
$return .= '</li>'; //end terms li
} //end foreach term
$return .= '</ul>';
return $return;
}
