如何在 WordPress 中获取自定义分类法的所有父/子类别 [英] How to get all parents/children categories of a custom taxonomy in WordPress

问题描述

我正在开发一个自定义 WordPress 主题，我想显示所有分类列表

例如，如果我想要这个结构:

1. 父类别 1

   • 儿童类别 1
   • 儿童类别 2
   • 儿童类别 3<块引用>

     1.1 - 孙子类别 1

2. 父类别 2

   • 儿童类别 4
   • 儿童类别 5<块引用>

     2.1.- 大孩子类别 2

你们能帮我解决这个难题吗

解决方案

要创建此结构，使用辅助数组可能是解决方案.这不是一个 100% 的解决方案，它只会让您启动，您可以从这里开始，因为单独解决它会更有帮助.

$all_terms = array();$taxonomy = '类别';$parent_args = ['分类' =>$分类法，'父母' =>0,'hide_empty' =>错误的];$parent_terms = get_terms( $parent_args );foreach ( $parent_terms 作为 $parent_term ) {$all_terms[ $parent_term->term_id ] = get_all_term_children( $parent_term, $taxonomy );}函数 get_all_term_children( $term, $taxonomy ){if ( is_wp_error( get_term_children( $term->term_id, $taxonomy ) ) ) {返回;}返回 get_term_children( $term->term_id, $taxonomy );}

I’m working on a custom WordPress theme and I want to show all the taxonomies list

So, for example, if I want this structure:

1. Parent Category 1

   • Child Category 1
   • Child Category 2
   • Child Category 3

     1.1 - Grand Child Category 1

2. Parent Category 2

   • Child Category 4
   • Child Category 5

     2.1. - Grand Child Category 2

can you guys please help me to solve this puzzle

解决方案

To create this structure, maybe going with a helper array is the solution. This is not a 100% solution it will just give you start up and you can go from here since figuring it out all alone will be more helpful.

$all_terms = array();
$taxonomy = 'category';
$parent_args = [
    'taxonomy'     => $taxonomy,
    'parent'        => 0,
    'hide_empty'    => false
];
$parent_terms = get_terms( $parent_args );

foreach ( $parent_terms as $parent_term ) {
   $all_terms[ $parent_term->term_id ] = get_all_term_children( $parent_term, $taxonomy );
}

function get_all_term_children( $term, $taxonomy ){
    if ( is_wp_error( get_term_children( $term->term_id, $taxonomy ) ) ) {
        return;
    }

    return get_term_children( $term->term_id, $taxonomy );
}
