我试图以保持层次结构的方式查询自定义分类术语。

这是我正在使用的代码。。

function ev_test_data() {
    $title = \'Mens Levi\\\'s Jeans\';
    $titles = str_replace( array("\'", \'"\', \'-\', \'\\\\\' ), \'\', explode( \' \', trim($title)) );
    $cats = array();
    foreach ( $titles as $kw ) {
        $terms = get_terms( array(
            \'taxonomy\' => \'product_cat\',
            \'orderby\' => \'parent\', // I guess this is where I am lost.
            \'hide_empty\' => false,
            \'name__like\' => $kw,
        ) );
        foreach ( $terms as $term ) {
            $cats[] = $term->term_id;
        }
    }

    $finals = array();
    foreach ( $cats as $cat ) {
        $catobj = get_term_by( \'id\', $cat, \'product_cat\' );
        $tree = \'\';
        $ancentors = array_reverse(get_ancestors( $cat, \'product_cat\', \'taxonomy\' ), true);
        $i=1;
        foreach ( $ancentors as $ancentor ) {
            $sterm = get_term_by( \'id\', $ancentor, \'product_cat\' );
            $tree .= $i == 1 ? \'<b>\' . $sterm->name . \'</b>\' : \' > \' . $sterm->name;
            $i++;
        }
        $tree .= \' > \' . $catobj->name;
        $finals[$cat] = $tree;
    }

    echo \'<pre>\' . print_r( $finals, true ) . \'</pre>\'; 
}  

这将生成此列表。

Array
(
    [4638] => Fashion > Womens Clothing
    [4699] => Fashion > Womens Handbags & Bags
    [4709] => Fashion > Womens Shoes
    [4461] => Fashion > Mens Accessories
    [4493] => Fashion > Mens Clothing
    [4512] => Fashion > Mens Shoes
    [4603] => Fashion > Womens Accessories
    [4779] => Fashion > Vintage > Mens Vintage Clothing
    [4821] => Fashion > Vintage > Womens Vintage Clothing
    [4290] => Fashion > Kids Clothing, Shoes & Accs > Boys Clothing (Sizes 4 & Up) > Jeans
    [4319] => Fashion > Kids Clothing, Shoes & Accs > Girls Clothing (Sizes 4 & Up) > Jeans
    [4354] => Fashion > Kids Clothing, Shoes & Accs > Unisex Clothing > Jeans
    [4500] => Fashion > Mens Clothing > Jeans
    [4660] => Fashion > Womens Clothing > Jeans
    [4666] => Fashion > Womens Clothing > Maternity > Jeans
)  

然而，这个列表并没有按我想要的顺序排列。我需要按层次顺序排序。像这样的。

Array
(
    [4493] => Fashion > Mens Clothing
    [4500] => Fashion > Mens Clothing > Jeans
    [4638] => Fashion > Womens Clothing
    [4660] => Fashion > Womens Clothing > Jeans
    [4666] => Fashion > Womens Clothing > Maternity > Jeans
    [4699] => Fashion > Womens Handbags & Bags
    [4709] => Fashion > Womens Shoes
    [4603] => Fashion > Womens Accessories
    [4512] => Fashion > Mens Shoes
    [4461] => Fashion > Mens Accessories
    [4779] => Fashion > Vintage > Mens Vintage Clothing
    [4821] => Fashion > Vintage > Womens Vintage Clothing
    [4290] => Fashion > Kids Clothing, Shoes & Accs > Boys Clothing (Sizes 4 & Up) > Jeans
    [4319] => Fashion > Kids Clothing, Shoes & Accs > Girls Clothing (Sizes 4 & Up) > Jeans
    [4354] => Fashion > Kids Clothing, Shoes & Accs > Unisex Clothing > Jeans

)

这可以使用WordPress内置函数来完成吗？如果不是，自定义查询的逻辑是什么？我并没有要求为我做这件事，但任何帮助或指导或headstart都会很好。

谢谢
