Question

我搜索了网站，但没找到我要找的东西。我有一个正常运行的代码，只有输出错误，这就是为什么我认为它不起作用。

到目前为止，这是我的代码：

这是函数：

function getPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return '0 View';
    }
    return $count.' Views';
}

// function to count views.
function setPostViews($postID) {
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}

// Add it to a column in WP-Admin - (Optional)
add_filter('manage_posts_columns', 'posts_column_views');
add_action('manage_posts_custom_column', 'posts_custom_column_views',5,2);
function posts_column_views($defaults){
    $defaults['post_views'] = __('Views');
    return $defaults;
}
function posts_custom_column_views($column_name, $id){
    if($column_name === 'post_views'){
        echo getPostViews(get_the_ID());
    }
}

$args = array(  'numberposts'  => 4,  /* get 4 posts, or set -1 for all */
                'orderby'      => 'meta_value_num',  /* this will look at the meta_key you set below */
                'meta_key'     => 'post_views_count',
                'order'        => 'DESC',
                'post_type'    => 'post',
                'post_status'  => 'publish'
            );
$myposts = get_posts( $args );
foreach( $myposts as $mypost ) {
    $id = $mypost->ID;
            $post_views = intval($post->views);
            $post_title = get_the_title($post);
            $post_title = $post->post_title;

}

提前非常感谢你。

尝试将'orderby' => 'meta_value_num'更改为'orderby' => 'meta_value meta_value_num'或'orderby' => 'meta_value_num meta_value'。我看到这个解决方案适用于某些人。

我实际上有一个非常类似的问题。尝试转储SQL（这里的教程：http://ben.lobaugh.net/blog/45390/wordpress-how-to-view-the-sql-query-generated-by-wp_query）并查看它的外观。我遇到这个问题时发现SQL错了。
