//实例化上传类     public function upload() {               $upload = new Upload();        $upload->maxSize = 10 * 1024 * 1024;        $upload->exts = array('jpg', 'jpeg', 'gif', 'txt','zip');        $upload->savePath = './';        $upload->hash = false;        $info = $upload->upload();        if (!$info) {            $this->error($upload->getError());        }         else{            foreach ($info as $file) {                $uploadFile=$file['savepath'].$file['savename'];                echo $uploadFile;            }                  }    }    //添加文章    public function addArticle(){    	 $sort = $_POST['sort'];    	 $title = $_POST['title'];    	 $intro = $_POST['intro'];    	 $pic = $_POST['pic'];    	 $content = $_POST['content'];       	 $articleSort= D('Article')->addArticle($sort,$title,$intro,$pic,$content);         $this->display('Index/AddArticle');    }

在做一个添加文章的功能。添加文章时用户可以先ajax无刷新上传文件,然后编辑文章后点发表文章按钮。有点类似QQ邮箱那种。
代码里 upload() 是上传文件的方法,addArticle()是添加文章的方法。
用户在上传文件时就会执行upload()方法把文件上传到指定的目录。我想用户在点击发布文章按钮时在addArticle()方法里获取upload()的变量$uploadFile,即用户上传文件的目录,然后和文章内容一起存储在数据库中。
简单来说我在addArticle()方法里要用到upload() 方法里的变量$uploadFile
求助各位大神

定义类属性。

由  添加文章时用户可以先ajax无刷新上传文件 可知
你的 upload 和 addArticle 是分开执行的
那么你就得在服务器上缓存 upload 的结果,在执行 addArticle 时取回

缓存这方法不错

用session缓存结果好么,还是用其他方法

用 session 是可以的,缓存的只不过是文件名而已
也可以在 ajax 上传后,将回传的文件名写入表单控件,之后再和表单一起提交

在你的这个架构中,需要考虑到一个问题:操作夭折时的垃圾回收(上传图片后又放弃提交了,此时上传的文件就成了孤儿)
给个方案供你参考:
上传的文件不直接放到上传目录中而是先放到一临时目录中,待表单正式提交后再从临时目录 rename 到上传目录
这样只需定时清空临时目录就可以了

xuzuning版主说的非常好,我没考虑到的操作夭折也给参考方案。现在问题解决了,谢谢大神!!
