上传单个文件，此文以上传图片为例，上传效果如图所示

创建数据库upload_img,用于保存上传路径

CREATE TABLE `seminar_upload_img` (

  `id` int(11) NOT NULL AUTO_INCREMENT,

  `img_name` varchar(255) DEFAULT NULL COMMENT '图片名称',

  `img_url` varchar(255) DEFAULT NULL COMMENT '图片路径',

  `create_time` text,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=23 DEFAULT CHARSET=utf8;

在公共配置文件Common/Conf.php中连接数据库，并配置地址

return array(        'DB_TYPE'=>'mysql',    'DB_HOST'=>'127.0.0.1',    'DB_NAME'=>'seminar',    'DB_USER'=>'root',    'DB_PWD'=>'root',    'DB_PORT'=>3306,    'DB_PREFIX'=>'seminar_',    'DB_CHARSET'=>'utf8',        'SHOW_PAGE_TRACE'=>true,        /*地址替换*/    'TMPL_PARSE_STRING'=>array(        '__UPLOAD__'=>__ROOT__.'/Public/Uploads',    ),);

 

视图文件Upload/index.html中

                    
                             
     
                      
                   
      
     
        
     
      上传允许文件类型：'jpg', 'gif', 'png', 'jpeg'图像文件后
     
        
     
            
                  
              
     
    

控制器UploadController.class.php中实现上传文件

namespace Home\Controller;use Think\Controller;class UploadController extends Controller {    public function index() {        $img=M('upload_img');        $sel=$img->order('create_time desc')->find();        $this->assign('data', $sel);        $this->display();    }    public function upload(){         $upload_img=M('upload_img');          if(!empty($_FILES)){              //上传单个图像                $upload = new \Think\Upload();// 实例化上传类                $upload->maxSize   =     1*1024*1024 ;// 设置附件上传大小                $upload->exts      =     array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型                $upload->rootPath  =      'Public/Uploads/'; // 设置附件上传根目录                $upload->savePath  =      ''; // 设置附件上传（子）目录                $upload->saveName=array('uniqid','');//上传文件的保存规则                $upload->autoSub  = true;//自动使用子目录保存上传文件                 $upload->subName  = array('date','Ymd');                // 上传单个图片                $info   =   $upload->uploadOne($_FILES['image']);                if(!$info) {
   // 上传错误提示错误信息                    $this->error($upload->getError());                }else{
   // 上传成功 获取上传文件信息                     $img_url=$info['savepath'].$info['savename'];                     $data['img_url']=$img_url;                     $data['img_name']=$info['savename'];                     $data['create_time']=NOW_TIME;                     $upload_img->create($data);                     $result=$upload_img->add();                     if(!$result){                         $this->error('上传失败！');                     }else{                         $this->success('上传成功');                     }                }          }    }}
