织梦dedecms友情连接添加或者更改时报错：PHP Fatal error: Call to undefined method Request::filter_files() in D\www\include\request.class.php on line 103 的解决办法：首先，打开/include/request.class.php文件，找到如下代码：//上传的文件处理if( isset($_FILES) && count($_FILES) > 0 ){$this->FilterFiles($_FILES);}$this->isinit = TRUE;//global变量//self::$forms['_global'] = $GLOBALS;}修改成：//上传的文件处理if( isset($_FILES) && count($_FILES) > 0 ){}$this->isinit = TRUE;//global变量//self::$forms['_global'] = $GLOBALS;}其实很简单，就是删除这句代码： $this->FilterFiles($_FILES);这样就成功解决了不能更改的问题！
