Wordpress：分类术语的自定义助行器

标签： wordpress categories taxonomy

我需要一些自定义Wordpress导航的帮助。

我有这个助手返回一个类别列表，显示每个级别的帖子数，但仅在第三级发布链接。到目前为止，非常好。

但是，如何根据自定义帖子类型分类法重写此内容？我已经摆弄了get_terms而不是get_categories，但我得到的只是一个空白屏幕。

以下是我要重写的类别版本的代码（抱歉，它很长）：

<?php

add_filter( 'cat_index', 'return_cat_index' );

function return_cat_index()
{

$categories = get_categories( array(
  'orderby'    => 'name',
  'order'      => 'ASC',
  'parent'     => 0,
  'hide_empty' => false,
  'exclude'    => 1,
  'count'      => false
));

$return .= '<nav id="cat-index">';
$return .= '<ul class="menu">';
  foreach ( $categories as $category ) {
    $subcats = get_categories( array(
      'parent'   => $category->cat_ID,
      'hide_empty' => false
    ));

  //count posts in category
  $count = 0;
  $taxonomy = 'category';
  $args = array(
    'child_of' => $category->cat_ID,
    );
  $tax_terms = get_terms($taxonomy,$args);
  foreach ($tax_terms as $tax_term) {
    $count +=$tax_term->count;
    }

  //sprintf categories
  $return .= sprintf(
    '<li id="category-%1$s" class="toggle">%3$s <span class="post-count">' . $count . '</span><span class="cat-description">%5$s</span>',
    $category->cat_ID,
    get_category_link( $category->term_id ),
    $category->name,
    $category->category_count,
    $category->description
  );

  //if subcats are available
  if( $subcats ){
    $return .= sprintf(
      '<ul id="subCategories-%1$s">',
      $category->cat_ID
      );

    foreach ( $subcats as $subcat ) {
      $subsubcats = get_categories( array(
        'parent'   => $subcat->cat_ID,
        'hide_empty' => false
      ));

      //count posts in subcategory
      $countsub = 0;
      $taxonomy = 'category';
      $args = array(
        'child_of' => $subcat->cat_ID,
        );
      $tax_term_subs = get_terms($taxonomy,$args);
      foreach ($tax_term_subs as $tax_term_sub) {
        $countsub +=$tax_term_sub->count;
      }

      //sprintf subcats
      $return .= sprintf(
        '<li id="subCategory-%1$s" class="toggle">%3$s <span class="post-count">' . $countsub . '</span><span class="cat-description">%5$s</span>',
        $subcat->cat_ID,
        get_category_link( $subcat->cat_ID ),
        $subcat->name,
        $subcat->category_count,
        $subcat->description            
      );

      //if subsubcats are available
      if( $subsubcats ) {
        $return .= sprintf(
          '<ul id="subSubCategories-%s">', 
                      $subcat->cat_ID
                    );

                  foreach ( $subsubcats as $subsubcat ){

          //sprintf subsubcats
          $return .= sprintf(
            '<li id="subsubCategory-%1$s" class="toggle">%3$s <span class="post-count">%4$s</span><span class="cat-description">%5$s</span>',
            $subsubcat->cat_ID,
            get_category_link( $subsubcat->cat_ID ),
            $subsubcat->name,
            $subsubcat->category_count,
            $subsubcat->description
          );

          //print posts
          $the_query = new WP_Query(array( 'post_type' => 'bestpractices', 'cat' => $subsubcat->cat_ID )); ?>

          <?php if ( $the_query->have_posts() ) : 
            $return .= '<ul>';
            while ( $the_query->have_posts() ) : $the_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 .= '</ul>'; //end subsubcat ul
      }
      else{} //endif subsubcats

      $return .= '</li>'; //end subcat ul
    }

    $return .= '</ul>'; //end subcat ul
  }
  else{} //endif subcats

  $return .= '</li>'; //end category li
} //end for each category

$return .= '</ul>';
$return .= '</nav>';

return $return;
}
?>

修改 - 更新代码： 我正在从头开始重建它，解决了空白屏幕问题。但是新代码不会返回任何用于嵌套子项的term_ID。

有什么想法吗？

add_filter( 'ap14-index', 'return_ap14_index' );

function return_ap14_index()
{

  $taxonomies = array( 
    'ap14',
  );

  $args = array(
    'orderby'           => 'name', 
    'order'             => 'ASC',
    'hide_empty'        => false, 
    'exclude'           => array(), 
    'exclude_tree'      => array(), 
    'include'           => array(),
    'number'            => '',
    'fields'            => 'all',
    'slug'              => '',
    'parent'            => '',
    'hierarchical'      => true,
    'child_of'          => 0,
    'get'               => '', 
    'name__like'        => '',
    'description__like' => '',
    'pad_counts'        => false,
    'offset'            => '',
    'search'            => '',
    'cache_domain'      => 'core'
  );

  $terms = get_terms($taxonomies, $args);

  $return .= '<ul class="menu cat-index">';

     foreach ( $terms as $term ) {

       $subterms = get_terms( array(
        'parent'   => $term->term_id,
        'hide_empty' => false
        ));

       $return .= sprintf(
         '<li>%1$s',       
         $term->name
       );

       //if subterms are available
       if( $subterms ){
        $return .= sprintf(
          '<ul id="subTerms-%1$s">',
          $term->term_id
          );

        $return .= '</ul>'; //end subcat ul
      }


      $return .= '</li>'; //end category li
    } //end for each category

  $return .= '</ul>';

  return $return;
}

编辑：再次更新，抱歉。 Term_ID现在返回正常，但子术语仍未显示。输出应该是嵌套列表，子术语显示在每个父术语li中。但他们只是没有显示，我认为这段代码不能按预期工作：

foreach ( $terms as $term ) {         
  $subterms = get_terms( array(
    'parent'   => $term->term_id,
    'hide_empty' => false
  ));
}

这是完整的代码：

add_filter（'cat_index'，'return_cat_index'）; 

function return_cat_index()
{

  $taxonomies = array( 
    'taxonomy_name',
  );

  $args = array(
    'orderby'           => 'name', 
    'order'             => 'ASC',
    'hide_empty'        => false, 
    'exclude'           => array(), 
    'exclude_tree'      => array(), 
    'include'           => array(),
    'number'            => '',
    'fields'            => 'all',
    'slug'              => '',
    'parent'            => 0,
    'hierarchical'      => true,
    'child_of'          => 0,
    'get'               => '', 
    'name__like'        => '',
    'description__like' => '',
    'pad_counts'        => false,
    'offset'            => '',
    'search'            => '',
    'cache_domain'      => 'core'
