如何在WordPress上获取帖子的自定义文件？

This method get_posts() return all fields!

But i need to get custom fields, for example i wanna get only id and title and their categories name.

I think by passing parameter you could get what you want.

    $args = array( 
      'numberposts'     => -1, // -1 is for all
      'post_type'       => 'movie', // or 'post', 'page'
      'orderby'         => 'title', // or 'date', 'rand'
      'order'       => 'ASC', // or 'DESC'
    );

    // Get the posts
    $posts = get_posts($args);

    // If there are posts
    if($posts){
      // Loop the posts
      foreach ($posts as $post){
        var_dump($mypost->ID); // you have ID here
      }
    }
