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');
}
}
}
}
}
