要修改的是wordpress\wp-admin\includes\file.php

查找：
$filename = wp_unique_filename( $uploads['path'], $file['name'], $unique_filename_callback );

在其后加上：
$fileTypeNameArr =explode("." , $filename);
$countNum=count($fileTypeNameArr)-1;
$fileExt =  $fileTypeNameArr[$countNum]; //取得所上传文件后缀名
$filename = time().'-'.rand(0,999999999).'.'.$fileExt;//将文件由原名改为时间戳
