Question

我想在WordPress中发布前端的附件，这是我的代码：

表单流程：

global $post;

if ( $_FILES ) {
    $files = $_FILES['upload_attachment'];
    foreach ($files['name'] as $key => $value) {
        if ($files['name'][$key]) {
            $file = array(
                'name' => $files['name'][$key],
                'type' => $files['type'][$key],
                'tmp_name' => $files['tmp_name'][$key],
                'error' => $files['error'][$key],
                'size' => $files['size'][$key]
            );

            $_FILES = array("upload_attachment" => $file);

            foreach ($_FILES as $file => $array) {
                $newupload = insert_attachment($file,0);
            }
        }
    }
}

处理上传的功能：

function insert_attachment($file_handler,$post_id,$setthumb='false') {
    // check to make sure its a successful upload
    if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false();

    require_once(ABSPATH . "wp-admin" . '/includes/image.php');
    require_once(ABSPATH . "wp-admin" . '/includes/file.php');
    require_once(ABSPATH . "wp-admin" . '/includes/media.php');

    $attach_id = media_handle_upload( $file_handler, $post_id );

    if ($setthumb) update_post_meta($post_id,'_thumbnail_id',$attach_id);
    return $attach_id;
}

我想设置附件的post_author，因为当前默认为当前登录用户。

我尝试在函数中添加以下内容，但它似乎不起作用：

$my_post = array(
    'ID'          => $attach_id,
    'post_author' => 2
);
wp_update_post( $my_post );

Answer 1

if ($setthumb) {
    update_post_meta($post_id, '_thumbnail_id', $attach_id);
}

根据wp_update_post（codex），你必须通过POST_ID，我不确定你的$attach_id是否是帖子ID，根据update_post_meta($post_id, '_thumbnail_id', $attach_id);通过$post_id

$my_post = array(
  'ID' => $post_id,
  'post_author' => 2
);
wp_update_post( $my_post );

Answer 2

不太确定发生了什么，我重复了这个并且似乎工作了！只是想更新，其他人也有同样的问题！

   $my_post = array(
      'ID'           => $attach_id,
      'post_author' => 2
    );
    wp_update_post( $my_post );

WordPress insert_attachment set post_author
