试试这个。用于get\\u帖子中的tag\\u id。

$tax_terms = get_terms(\'media_category\', \'orderby=count&order=DESC&hide_empty=0\');

foreach ( $tax_terms as $tax_term ) {

$posts = get_posts(array(
                "meta_key" => \'select\', 
                "meta_value" => 1,
                "tag_id" => 5,
                "post_mime_type" => "video",
                "taxonomy" => $tax_term->taxonomy,
                "term" => $tax_term->slug,
                "numberposts" => 100, 
                "posts_per_page" => 100));
