ckfinder自动重命名

打开/ckfinder/core/connector/php/php5/CommandHandler/FileUpload.php
找到
if ($sFileName != $sUnsafeFileName) {
      $iErrorNumber = CKFINDER_CONNECTOR_ERROR_UPLOADED_INVALID_NAME_RENAMED;
}
在其下方加入以下代码即可

$sExtension=CKFinder_Connector_Utils_FileSystem::getExtension($sFileName);
$sFileName = date("YmdHis")."_".rand(100000,999999).".".$sExtension;
