我想在我的wp上显示登录用户帖子的链接列表。所以我开始这样做：

$posts_array = get_posts( array( \'post_type\' => \'download\', \'post_status\' => \'publish\' ) );
//$posts_array = apply_filters( \'downloads_shortcode\', $posts_array );
foreach($posts_array as $post) {
    setup_postdata($post);
    $title = "<a href=". get_permalink( $post->ID ) . ">" . $post->post_title . "</a>";
    echo $title;
}

但功能似乎并不关心用户的能力。我使用一个名为“组”的插件来要求具有查看帖子的功能。如果功能缺失，页面上的所有帖子都会被隐藏。我很困惑，因为wp本身使用get\\u posts（）。如何做到这一点？

//通过Ravs提示，我能够做到这一点：我扩展了插件组：

add_filter( \'get_posts\', array( __CLASS__, "get_posts" ), 1 );
/**
 * Filter posts by access capability.
 *
 * @param array $posts
 */
public static function get_posts( $posts ) {
    $result = array();
    $user_id = get_current_user_id();
    foreach ( $posts as $post ) {
        if ( self::user_can_read_post( $post->ID, $user_id ) ) {
            $result[] = $post;
        }
    }
    return $result;
}

并应用了我已经试验过的过滤器：

$posts_array = apply_filters( \'get_posts\', $posts_array );

谢谢你。

$posts_array = get_posts( array( \'post_type\' => \'download\', \'post_status\' => \'publish\' ) );
//$posts_array = apply_filters( \'downloads_shortcode\', $posts_array );
foreach($posts_array as $post) {
    setup_postdata($post);
  if ( is_user_logged_in() ){
    $title = "<a href=". get_permalink( $post->ID ) . ">" . $post->post_title . "</a>";
    echo $title;
  }
  else{
    // do something
  }
}
