编程添加wordpress后附附件（pdf，word，excel或ppt文件）

Question

programattically我正在扫描一个directoy的文件（完成），在我插入每个文件后作为一个职位（完成），同时每个职位必须作为附件插入并保存在wordpress uploads文件夹中。

我需要插入附件的详细信息，并保存相应的文件，我坚持的那部分，这里是我写

<?php

     foreach ($dirs as $d) $alldirs[] = basename($d); 
    } 
    foreach ($dirs as $dir) listfolders($dir); 
    return $alldirs; 
} 

$folder_list = listfolders($directory); // Function to get all the folders and subfolders 

foreach($folder_list as $folder_name){ // Saving Folders as Tags in wp_bdqueries_tags table

我不得不建立一个类似的代码一种解决方案，这就是我如何取得成果。我希望以下代码片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);
