Wordpress术语列表的帖子

Question

在Wordpress中,我正在构建一个索引页面,我在表格中列出了我博客的所有文章.该表的每一行都具有以下结构:帖子标题,属于某个组的术语.例如,如果它是关于电影:

 Blade Runner       | noir, science fiction
 Gone with the Wind | dramatic

关键是:当我有多个术语时,会出现一些奇怪的错误,它会返回一个空集,或者有时会列出错误的术语.我很困惑,因为我无法弄清楚为什么会这样.这就是我获取数据的方式.

//Loops through the articles in the table wp_posts
foreach($results as $result){
    $metaStr = "";
    $id = $result->ID;
    $query = "
        SELECT name 
        FROM wp_term_relationships 
        INNER JOIN wp_terms
        ON term_id = term_taxonomy_id
        WHERE object_id = $id AND term_taxonomy_id IN (6, 7, 8, 9, 14, 15, 18, 22, 24, 30)
    ";
    $metas = $wpdb->get_results($query);
    $count = 0;
    foreach($metas as $meta){
        if($count > 0){
            $metaStr .= "<br />";
        }
        $metaStr .= $meta->name;
        $count++;
    }
    print $metaStr;
}

有人可以帮忙吗？我究竟做错了什么？有一个更好的方法吗？干杯

放下以下函数,只传递post id,在你的情况下$ result-> ID;

function my_get_term_of_post($postId){
$metaStr="";
$term_list = wp_get_post_terms($postId, 'console', array("fields" => "all"));
$i=1;
foreach($term_list as $termSingle){
    if($i==1)
     $metaStr=$termSingle->name;
    else
     $metaStr.= "<br/>".$termSingle->name;
    $i++;
}
return $metaStr;

}

$ term_list = my_get_term_of_post($ result-> ID);
