Question

我使用register_post_type（）函数在WP中创建了一个自定义帖子类型（遵循this article中提供的示例）

它工作正常，但我希望能够在查看列表时过滤管理面板中的帖子。现在我只能按发布日期进行过滤，但我想按作者或任意字段（包括自定义）的值过滤说明。

当我注册自定义帖子类型时，这可以在functions.php中实现吗？这是我的代码：

// A custom post type for 'film' items
function film_custom_init() {
    $args = array(
      'public' => true,
      'label'  => 'Films',
      'show_ui' => true,
      'show_in_menu' => true,
      'rewrite' => array( 'slug' => 'film' ),
      'support' => array( 'title', 'editor', 'author', 'custom-fields' )
    );
    register_post_type( 'film', $args );
}

add_action( 'init', 'film_custom_init' );

Answer 1

在主题的functions.php中添加此代码。希望这会有所帮助

  add_action( 'restrict_manage_posts', 'custom_post_author_wise_filter' );

    function custom_post_author_wise_filter(){
        if (isset($_GET['post_type']) && 'film' == $_GET['post_type']){
            wp_dropdown_users( array(
                'show_option_all' => __( 'Show All Authors', 'twentyfifteen' ),
                'name' => 'author_id',
                'selected' => $_GET['author_id']
            ));
        }
    }
    add_filter( 'parse_query', 'parse_query_custom_post_author_wise_filter' );

    function parse_query_custom_post_author_wise_filter( $query ){
        global $pagenow;
        if ( isset($_GET['post_type']) 
             && 'film' == $_GET['post_type'] 
             && is_admin() && 
             $pagenow == 'edit.php' 
             && isset($_GET['author_id']) 
             && $_GET['author_id'] != '') {
            $query->query_vars['author'] = $_GET['author_id'];
        }
    }

chaneg与您在高级自定义字段中创建的字段名的关系。 repalce团队发布到你的帖子typein钩子名称和其他位置，并将整个代码放在你的functions.php

add_filter('manage_edit-team_columns', 'custom_posts_table_head');
    function custom_posts_table_head( $columns ) {
        $columns['genre']  = 'Genre';
        return $columns;

    }
    add_action( 'manage_team_posts_custom_column', 'custom_posts_table_content', 10, 2);
    function custom_posts_table_content( $column_name,$post_id ) {
        if( $column_name == 'genre' ) {
            $post = get_field( 'relationship', $post_id );
            echo $post->post_title;
        }
    }

    add_action( 'restrict_manage_posts', 'custom_post_author_wise_filter' );
