经过相当多的搜索和广泛的测试，我找到了答案。

将此代码添加到主题的函数中。php：

function set_the_terms_in_order ( $terms, $id, $taxonomy ) {
    $terms = wp_cache_get( $id, "{$taxonomy}_relationships_sorted" );
    if ( false === $terms ) {
        $terms = wp_get_object_terms( $id, $taxonomy, array( \'orderby\' => \'term_order\' ) );
        wp_cache_add($id, $terms, $taxonomy . \'_relationships_sorted\');
    }
    return $terms;
}
add_filter( \'get_the_terms\', \'set_the_terms_in_order\' , 10, 4 );

function do_the_terms_in_order () {
    global $wp_taxonomies;  //fixed missing semicolon
    // the following relates to tags, but you can add more lines like this for any taxonomy
    $wp_taxonomies[\'post_tag\']->sort = true;
    $wp_taxonomies[\'post_tag\']->args = array( \'orderby\' => \'term_order\' );    
}
add_action( \'init\', \'do_the_terms_in_order\');

我知道这是一种欺骗，但你可以用Simple Custom Post Order 插件。它是免费的，并且允许您对文章类型之外的分类法进行排序。

我一直在努力寻找自定义分类法中按字母顺序排列的子术语的答案。。。我不建议更改核心WP文件，所以下面是我添加到分类中的内容。php文件列出自定义分类描述，并按字母顺序链接到子术语。修改以满足您的需要，我希望这对其他人有所帮助。

// Get Main Taxonomy for use in template file
$term = get_term_by( \'slug\', get_query_var( \'term\' ), get_query_var( \'taxonomy\' ) );
$termTaxonomy = $term->taxonomy;

<h1><?php echo apply_filters( \'the_title\', $term->name ); ?></h1>

<?php // test for description before unleashing a div 
if ( !empty( $term->description ) ): 
  echo \'<div class="description">\';
  echo $term->description;
  echo \'</div>;
endif; ?>

// Now get children terms, using get_term & \'child_of\' get\'s us alphabetical order
$termchildren = get_terms( $termTaxonomy, array(
  \'child_of\'     => $term->term_id,
  \'hierarchical\' => 0,
  \'fields\'       => \'ids\',
  \'hide_empty\'   => 0
) );

// Make an alphabetical linked list
echo \'<ul>\';
foreach ($termchildren as $child) {
  $term = get_term_by( \'id\', $child, $termTaxonomy );

  // Modify this echo to customize the output for each child term
  echo \'<li><a href="\' . get_term_link( $term->name, $termTaxonomy ) . \'" alt="\' .$term->description. \'">\' . $term->name . \'</a></li>\';
}
echo \'</ul>\';

在网页中显示好的顺序之后，可能是：

将“orderby”=>“term\\u group”放入wp\\u get\\u post\\u术语中

例子：

“poste”是我的自定义分类名称，请输入您的

$poste =  wp_get_post_terms($post->ID, \'poste\', array("fields" => "names", "orderby" => "term_group"));
        if(!empty($poste[0])){ echo $poste[0];}
        if(!empty($poste[1])){
          echo " - ", $poste[1]; }
