get_posts-按作者ID获取所有帖子

我想按特定作者ID(当前用户)获取所有帖子.稍后,我要选择该用户(ASC)发表的第一篇文章. 我猜我在get_posts中使用的参数不正确,是吗?$ current_user_posts 始终包含一个数组,其中所有博客帖子都位于多个不同的WP_Post对象中.

 global $current_user;
get_currentuserinfo();                      

$args = array(
    'author'        =>  $current_user->ID, // I could also use $user_ID, right?
    'orderby'       =>  'post_date',
    'order'         =>  'ASC' 
    );

// get his posts 'ASC'
$current_user_posts = get_posts( $args );

I want to get all posts by certain author id (current user). Later, I want to pick the first post made by this user (ASC). I guess I do not use the right arguments in get_posts, am I? $current_user_posts always contains an Array with all blog posts in multiple different WP_Post Objects.

global $current_user;
get_currentuserinfo();                      

$args = array(
    'author'        =>  $current_user->ID, // I could also use $user_ID, right?
    'orderby'       =>  'post_date',
    'order'         =>  'ASC' 
    );

// get his posts 'ASC'
$current_user_posts = get_posts( $args );

- 从版本4.5.0开始不推荐使用get_currentuserinfo().替换为:`$ current_user=wp_get_current_user();`
  
  get_currentuserinfo() is deprecated since version 4.5.0. Replace with: `$current_user = wp_get_current_user();`

 global $current_user;                     

$args = array(
  'author'        =>  $current_user->ID, 
  'orderby'       =>  'post_date',
  'order'         =>  'ASC',
  'posts_per_page' => -1 // no limit
);


$current_user_posts = get_posts( $args );
$total = count($current_user_posts);

并仅循环当前用户的帖子

global $current_user;                     

$args = array(
  'author'        =>  $current_user->ID, 
  'orderby'       =>  'post_date',
  'order'         =>  'ASC',
  'posts_per_page' => -1 // no limit
);


$current_user_posts = get_posts( $args );
$total = count($current_user_posts);

and just loop the current user posts

除了发布代码外,您还能解释上述代码的作用吗,谢谢您

Can you also explain what the above code does in addtion to posting the code, it will be helpful, thanks

其工作原理(wp4.9.7)

  $user_id = get_current_user_id();
 $args=array(
 'post_type' => 'POSTTYPE',
 'post_status' => 'publish',
 'posts_per_page' => 1,
 'author' => $user_id
  );

$current_user_posts = get_posts( $args );
$total = count($current_user_posts);
wp_die( '<pre>' .  $total . '</pre>' );

its work by (wp4.9.7)

 $user_id = get_current_user_id();
 $args=array(
 'post_type' => 'POSTTYPE',
 'post_status' => 'publish',
 'posts_per_page' => 1,
 'author' => $user_id
  );

$current_user_posts = get_posts( $args );
$total = count($current_user_posts);
wp_die( '<pre>' .  $total . '</pre>' );

我有点困惑.如果您想从posts数组中获取一个元素,则可以这样获取:

重置($ current_user_posts)-第一篇文章
end($ current_user_posts)-后期发布

但是,如果您只想通过get_posts()获得一篇帖子,则可以使用posts_per_page参数来限制结果.

 $args = array(
    'author'        =>  $current_user->ID,
    'orderby'       =>  'post_date',
    'order'         =>  'ASC',
    'posts_per_page' => 1
    );

有关您可以在 WP查询类参考页上获得的参数的更多信息(get_posts()与WP Query使用相同的参数.

I'm a bit confused. If you want to get onlya element from the posts array you can get it like this:

reset($current_user_posts) - first post
end($current_user_posts) - lat post

But if you want to get just one post with the get_posts() you can use the posts_per_page argument to limit the results.

$args = array(
    'author'        =>  $current_user->ID,
    'orderby'       =>  'post_date',
    'order'         =>  'ASC',
    'posts_per_page' => 1
    );

More info about parameters you can get on WP Query Class Reference page (get_posts() takes same parameters as WP Query).

您的$ args工作正常,但我没有得到您的第一个答案.如何使用$ current_user_posts.可以展示给我吗?

your $args work fine but I don't get your first answer. How to use $current_user_posts. Could you show me?

如果要打印第一篇文章的标题,应使用:`echo $ current_user_posts [0] ['title']`."标题"是您从阵列中获得所需内容的关键.您可以通过print_r(array_keys($ current_user_posts))获得的密钥的完整列表. "如何使用"取决于您要如何使用它.

If you want to print the title of the first post you should use: `echo $current_user_posts[0]['title']`. The 'title' is the key for what you need from array. The full list of keys you cang get with `print_r(array_keys($current_user_posts))`. "How to use" it depends on what you want to do with it.

您可以通过以下方式获取ID:$ current_user_posts [0] ['ID']

You can get the id with: $current_user_posts[0]['ID']

$ current_user_posts [0] ['ID']不起作用.但是第一个添加"numberposts"或"posts_per_page"(使用等于)的解决方案可以正常工作.ty

$current_user_posts[0]['ID'] does not work. but the first solution with adding 'numberposts' or 'posts_per_page' (used equal) works fine. ty

@kindo,对不起,忘记了get_posts()返回post对象数组.使用`$ current_user_posts [0]-> ID`

@kindo, Sorry, forgot that `get_posts()` returns array of post objects. Use `$current_user_posts[0]->ID`
