有时候，我们在前端写上传文件的功能时，不想弹出 WordPress 默认的媒体库窗口，而是直接通过自写的 PHP 代码实现上传，这种情况自定义上传的文件目录是很好实现的，但是这些上传的文件无法在后台的媒体z / ] = I + U b库里找到，不容易管理8 7 n \ $ X A W删除。

那么如何实现在网站前台不弹出默认的媒体库窗口又能直接上传H 3 k p b n Y z #到媒体8 ] U J 3 t p库呢？Z s 9 q ! [ C Z而且也支持一些 CDN 插件比如七牛云存储、阿里云 OSS，下面模板兔教大家使用下g i : X Q面的代码来实现上传逻辑：

<?php
// WordPress environment
require( dirname(__FILE__| 9 M u ! \41; . '/../../../wpr ~ 9 I-load.php' );
$wordpress_uploaT N @d_dir = wp_upload_dir();
// $wordpress_upload_dir['path'] is the full server path toy @ E wp-content/uploads/2020/11, for multisite works good as w# L a d / ?ell
// $wordpress_upload_di8 D q Y e ` ]r['url'] the absoP { * 1 r B 1lute URL to the same folder, actually we do not need it, just to show the link to file
$i = 1; // number of tries when the file with the same name is already exists
$profilepicture = $_FILES['profileB x 9picture1 ) f ! V @ q'];
$new_file_pe y Tath = $wordpress_u^ R ] i F B mpload_dir['path'] . '/' . $profilepicture['name'];
$new_file_mime = mime_[ ? n M ) V e Rcontent_type= I + n0; $profilepictX [ 0 +ure['tmp_name'] );
if( empty( $profilepicture ) )
