如何调整以下代码段以应用于特定的自定义分类法？当前适用于职位类别

我使用以下函数：<?php display_cat_level(X,true); ?> 在我的主题文件中显示每个层次类别级别

function get_level($category, $level = 0)
{
    if ($category->category_parent == 0) {
        return $level;
    } else {
        $level++;
        $category = get_category($category->category_parent);
        return get_level($category, $level);
    }
}

function display_cat_level( $level = 0 , $link=false){

    $cats = get_the_category( );
    if( $cats ){
        foreach($cats as $cat){
            $current_cat_level = get_level($cat);
            if( $current_cat_level  == $level ){
                if($link==true) {
                    echo \'<a href="\'.get_category_link($cat->cat_ID).\'">\'.$cat->name."</a>";
                } else {
                    echo $cat->name."";
                }
            }
        }
    }
}

<?php 
function get_level_subject($category, $level = 0)
{
    if ($category->parent == 0) {
        return $level;
    } else {
        $level++;
        $category = get_term( $category->parent );
        return get_level_subject($category, $level);
    }
}

function display_cat_level_subject( $level = 0 , $link=false){

    $cats = get_the_terms( null, \'subject\' );
    if( $cats ){
        foreach($cats as $cat){
            $current_cat_level = get_level_subject($cat);
            if( $current_cat_level  == $level ){
                if($link==true) {
                    echo \'<a href="\'.get_term_link( $cat->term_id ).\'">\'.$cat->name."</a>";
                } else {
                    echo $cat->name."";
                }
            }
        }
    }
} 
?>
