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

#img{height:22px; border:#000 2px solid}

#button{height:30px; width:100px;}

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');

}

}

}

}

}
