我认为最好的选择是使用getPostViews() 计算并在其中合并一个系统，以附加trending 当你的计数器达到150时，立即向帖子发送条件。

这是我们的工作流程，请获取后期视图计数（，您已经在这样做了）

将当前计数与所需的150进行比较

使用wp_set_object_terms() 要附加trending 任职期限

代码中的

（我稍微修改了您的代码。另请注意，代码未经测试）

function getPostViews()
{
    // Check if we are on a single page, bail out if not
    if ( !is_single() )
        return false;

    // Get the current post id
    $current_post_id = get_queried_object_id();

    $count_key = \'post_views_count\';
    $count = get_post_meta( $current_post_id, $count_key, true );

    // Set up our function to set our term \'trending\'
    if ( $count >= 150 ) {
        /**
         * First check if the term is not yet set, if not, set the term
         * I have used trending as term slug. Change as needed
         * Also, add the correct taxonomy to which trending term belongs to
         *
         * @link https://codex.wordpress.org/Function_Reference/has_term
         */
        if ( !has_term( \'trending\', \'MY_TAX\', $current_post_id ) ) {
            /**
             * Append the term trending to the post
             *
             * @link https://codex.wordpress.org/Function_Reference/wp_set_object_terms
             */
            wp_set_object_terms( 
                $current_post_id, // Current post ID
               \'trending\', // Slug of term to append
               \'MY_TAX\', // Taxonomy that the term trending belongs to
               true // VERY VERY IMPORTANT, Append the term to the other existing terms
            );
        }
    }

    if( !$count ){

        delete_post_meta( $current_post_id, $count_key );
        add_post_meta( $current_post_id, $count_key, \'0\' );

    }

    $views = ( $count ) ? $count . \' Views\' : \'0 View\';
    return $views;

}

您只需在单个页面中使用以下代码

echo getPostViews();

剩下的由函数完成
