Homephp教程php手册ThinkPHP使用心得分享-上传类UploadFile的使用

上传类的使用很简单,如果是第一次使用上传功能的朋友需要注意的是html提交表单中的表单属性要加上 enctype属性,如:

复制代码 代码如下:


 


 
 
 

ThinkPHP的UploadFile类在文件../ThinkPHP/Extend/Library/ORG/Net/UploadFile.class.php中:

复制代码 代码如下:


        //引入UploadFile类
        import('ORG.Net.UploadFile');
        //实例化UploadFile类
        $upload  = new UploadFile();
        //设置文件大小
        $upload -> maxSize = 3292200;
        //设置文件保存规则唯一
        $upload->saveRule = 'uniqid';
        //设置上传文件的格式
        $upload -> allowExts = array('jpg','png','jpeg');
        //保存路径
        $upload->savePath ='./Public/Uploads/';
        //设置需要生成缩略图,仅对图像文件有效
        $upload->thumb = true;
        //设置需要生成缩略图的文件前缀
        $upload->thumbPrefix = 'm_';  //生产缩略图也可以根据需要生成1张或多张,2张:'m_,s_'
        //设置缩略图最大宽度
        $upload->thumbMaxWidth = '150';//2张的不同设置:'150,200'
        //设置缩略图最大高度
        $upload->thumbMaxHeight = '200';
        //删除原图
        $upload->thumbRemoveOrigin = true;
        //上传失败返回错误信息
        if(!$upload->upload()){
           $this->error($upload->getErrorMsg());
        }else{
           $this->success('上传成功');
           //获取上传文件的信息
           $inf= $upload->getUploadFileInfo();
        }

经过设置后就能轻松地上传文件,同时,$upload的getUploadFileInfo可以获取上传的文件的信息。
