我正在尝试从术语名称中获取术语ID，但无法找出此代码不起作用的原因。

$excludes = \'\';
    if($filtering_excludes) {

     $exclude_terms = explode(", ", $filtering_excludes);
        foreach ($exclude_terms as $exclude_term) {

            $term = get_term_by( \'name\',  $exclude_term,  $filtering_tax  );
             $exclude_term = $term->term_id;         

        }

        $excludes= implode(", ", $exclude_terms);

    }

当我在$exclude\\u上执行var\\u转储时，term is具有term id，但$excludes仍返回term名称。

我有类似的代码从name中获取类别id，它可以毫无问题地工作——这就是代码。

$excludes = \'\';
    if($filtering_excludes) {

     $exclude_cats = explode(", ", $filtering_excludes);
        foreach ($exclude_cats as &$exclude_cat) {
             $cat_id = get_category_by_slug($exclude_cat); 
            $exclude_cat = $cat_id->term_id;

        }

        $excludes= implode(", ", $exclude_cats);
    }

有人知道为什么我的$exlcudes for terms返回的是名称而不是id吗？

  $excludes = \'\';
        if($filtering_excludes) {

         $exclude_terms = explode(", ", $filtering_excludes);
            foreach ($exclude_terms as $exclude_term) {

                $term = get_term_by( \'name\',  $exclude_term,  $filtering_tax  );
                 $exclude_term_array[] = $term->term_id;         

            }

            $excludes= implode(", ", $exclude_term_array);

        }
