显示分配给按父子类别关系排序的帖子的类别（或来自其他分类法的术语）。类似于函数get\\u the\\u category\\u list（），它按名称对类别进行排序。此示例必须在循环内使用。

<?php
$taxonomy = \'category\';

// Get the term IDs assigned to post.
$post_terms = wp_get_object_terms(
    $post->ID,
    $taxonomy,
    array(
        \'fields\' => \'ids\'
    )
);

// Separator between links.
$separator = \', \';

if ( ! empty( $post_terms ) && ! is_wp_error( $post_terms ) ) {

    $term_ids = implode( \',\' , $post_terms );

    $terms = wp_list_categories( array(
        \'title_li\' => \'\',
        \'style\'    => \'none\',
        \'echo\'     => false,
        \'taxonomy\' => $taxonomy,
        \'include\'  => $term_ids
    ) );

    $terms = rtrim( trim( str_replace( \'<br />\',  $separator, $terms ) ), $separator );

    // Display post categories.
    echo  $terms;
}
