Question

要实现我的要求，我使用此代码

观看次数输出

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";    }
return $count.'';}

注册视图

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);    }}

输出管理面板中的观看次数

add_filter('manage_pages_columns', 'posts_column_views');
add_action('manage_pages_custom_column', 'posts_custom_column_views',10,2);
add_filter('manage_posts_columns', 'posts_column_views');
add_action('manage_posts_custom_column', 'posts_custom_column_views',10,2);
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());    }}

这很好用!!!

添加排序列

的功能

add_filter('manage_edit-post_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-page_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-slides_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-hp_highlights_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-portfolio_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-staff_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-services_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-testimonials_sortable_columns', 'add_views_sortable_column');
add_filter('manage_edit-faqs_sortable_columns', 'add_views_sortable_column');
function add_views_sortable_column($sortable_columns){
  $sortable_columns['post_views'] = 'views_views';
  return $sortable_columns;}

应该可以通过输入 /wp-admin/edit.php?orderby=views_views&order=desc 视图”列进行排序> 但实际上它排序的是“日期”而不是“观点”。

更改查询以对WordPress显示的列进行排序。按值为数字的随机字段排序

（方法1）

add_filter('pre_get_posts', 'add_column_views_request'); function add_column_views_request( $object ){ if( $object->get('orderby') != 'views_views' ) return; $object->set('meta_key', 'post_views'); $object->set('orderby', 'meta_value_num');}

（方法2）

add_action( 'pre_get_posts', 'add_column_views_request', 1 ); function add_column_views_request( $query ) { if ( $query->is_main_query() && ( $orderby = $query->get( 'orderby' ) ) ) { switch( $orderby ) { case 'views_views': $query->set( 'meta_key', 'post_views' ); $query->set( 'orderby', 'meta_value' ); break;}}}

（方法3）

add_filter('request', 'add_column_views_request'); function add_column_views_request( $vars ) { if ( 'views_views' == $vars['orderby'] ){ $vars['meta_key'] = 'post_views'; $vars['orderby'] = 'meta_value_num';} return $vars;}

但现在排序并未返回结果：“未找到任何条目。”

Answer 1

我应该做 方法1

 $object->set('meta_key', 'post_views_count');

方法2

 $query->set( 'meta_key', 'post_views_count' );

方法3

 $vars['meta_key'] = 'post_views_count';
