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
<!DOCTYPE html> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <style type="text/css"> #img{height:22px; border:#000 2px solid} #button{height:30px; width:100px;} </style> </head> <body> <div><notemply name="data"> <img src="__UPLOAD__/{$data[‘img_url‘]}" width="200" height="100"/> </notemply></div> <div class="result" >上传允许文件类型：‘jpg‘, ‘gif‘, ‘png‘, ‘jpeg‘图像文件后</div><br> <form action="{:U(‘upload/Upload‘)}" method="post" enctype="multipart/form-data"> <input type="file" name="image"/> <input type="submit" value="上传" id="button"> </form> </body> </html>
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‘); } } } } }
