ThinkPHP学习笔记(十四)上传文件

需要进行Action的设置,包括UploadFile的文件引入

<?php /** * 处理文件上传功能 * @author admin * *	上传多文件时; *	可以在input中个的name中后加入[];例如:file[] *	或者可以设置标示:file1,file2 * *	只有在插入数据库的时候才需要进行循环插入 */class FileAction extends Action{	public function index(){		$file=M('file');		$list=$file->select();		$this->assign('alist',$list);		$this->display();	}	function upload(){		//经过自定义模型		if (empty($_FILES)){			$this->error("必须选择上传文件");		}else {			$msg = $this->up();			if (isset($msg)){				$result=$this->insertDb($msg);				if ($result){					$this->success('上传成功');				}else{					$this->error('保存出错了那');				}			}else{				$this->error($msg);			}		}	}		private function insertDb($data){		$file=M('file');		$result=true;		for ($i = 0; $i data($data)->add()){				return false;			}		}		return true;	}		private function up(){		import('ORG.Net.UploadFile');		$upload=new UploadFile();		$upload->maxSize='1000000';//大小:-1不限制;单位是bytes		$upload->savePath='./Public/';//上传路径:建议以主路口或者平级目录的子目录来		$upload->saveRule='uniqid';//保存规则:默认是uniqid		$upload->hashType='MD5';//hash验证方法,默认是md5		$upload->autoCheck=false;		$upload->uploadReplace=true;		$upload->allowExts=array('jpg','png');//允许上传的文件格式		$upload->allowTypes=array('image/png','image/jpg');//文件的mime类型				$upload->thumb=true;//是否开启图片文件缩略图		$upload->thumbMaxWidth='100,500';//可以用,分割,写多个最大宽度		$upload->thumbMaxHeight='100,500';//与width一一对应		$upload->thumbPrefix='s_,m_';//缩略图文件前缀,与width一一对应//		$upload->thumbPath='';//缩略图的保存路径,如果为空直接上传至$upload->savePath//		$upload->thumbFile='';//缩略图的文件名,一般不会用,直接用前缀就可以了		$upload->thumbRemoveOrigin=1;//生成新图后是否删除原图		//		$upload->autoSub=false;//是否使用子目录进行保存//		$upload->subType='';//子目录创建方式,默认为hash创建,也可以设置为date//		$upload->dateFormat='';//子目录date方式的指定格式//		$upload->hashLevel='';//hash的层级				if ($upload->upload()) {			$msg=$upload->getUploadFileInfo();			dump($msg);			return $msg;		}else {			$this->error($upload->getErrorMsg());			return $upload->getErrorMsg();		}			}}?>
