以编程方式我正在扫描目录中的文件（完成），在我将每个文件作为帖子（完成）插入后，同时每个帖子必须作为附件插入并保存在wordpress uploads文件夹中。
我需要插入附件详细信息并保存相应的文件，我坚持使用该部分，这是我编写的代码

我必须建立类似的解决方案，这就是我取得成果的方式。我希望此代码段有助于解决您的问题：
/* $post_id is the id of the post which you want to associate the attachement. you don't need this if you don't want to associate attachment with any post */
/*read source file and upload it to destination folder*/
$upload_dir = wp_upload_dir();
$image_remote_path = $original_directory.'/'.$image;
$image_local_path = $upload_dir['path'].'/'.$image;
$image_local_url = $upload_dir['url'].'/'.basename( $image_local_path );
$remotehandle = fopen($image_remote_path, 'rb');
$localhandle = fopen($image_local_path, 'w');
while( $chunk = fread($remotehandle, 8192)) {
fwrite($localhandle, $chunk);
}
fclose($remotehandle);
fclose($localhandle);
/* end of uploading from source to destination */
$filetype = wp_check_filetype( basename( $image_local_path ), null );
// Prepare an array of post data for the attachment.
$attachment = array(
'guid' => $image_local_url,
'post_mime_type' => $filetype['type'],
'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $image_local_path ) ),
'post_content' => $image_caption_data[$i],
'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment( $attachment, $image_local_path, $post_id ); /*do not put post id if you don't want to associate with any post*/
require_once( ABSPATH . 'wp-admin/includes/image.php' );
// Generate the metadata for the attachment, and update the database record.
$attach_data = wp_generate_attachment_metadata( $attach_id, $image_local_path );
wp_update_attachment_metadata( $attach_id, $attach_data );
