PHP文件异步上传

利用一个js插件实现, 主要阐述一下前台部署代码和后台封装

前台JS调用代码

ajaxfileupload({url : url,secureuri : false,fileElementId : 'excel_orders_file',dataType : 'json',success : function(json, status) {if (!json.success) {alert(json.msg);} else {alert('导入成功!'+json.msg);}},});

后台文件上传类封装:

<?phprequire_once WEB_PATH.'include/util/TmpFile.cls.php';/**  * @author jixiaolong * @todo AjaxFileUpload插件配套的PHP类 *  */class AjaxFileUpload {private $uploadFile;private $tmpCopy;function __construct($fileElementName) {$this->tmpCopy = null;if (!array_key_exists($fileElementName, $_FILES)){$message = "没有找到fileElementName为{$fileElementName}的上传文件";throw new Exception($message, 0);}$this->uploadFile = $_FILES[$fileElementName];if ($this->hasUploadError()) {$error = $this->getUploadErrorMsg();throw new Exception($error, 0);}else if (!$this->hasUploadFile()) {$error = 'No file was uploaded..';throw new Exception($error, 0);}else{;}}/** *  */function __destruct() {$this->delFromTmpDir();}/** * 判断是否上传了文件 */private function hasUploadFile(){return !(empty($this->uploadFile['tmp_name']) || $this->uploadFile['tmp_name'] == 'none');}/** * 判断是否有上传错误 */private function hasUploadError(){return !empty($this->uploadFile['error']);}/** * 获取上传错误信息 */private function getUploadErrorMsg(){switch ($this->uploadFile ['error']) {case '1' :$error = 'The uploaded file exceeds the upload_max_filesize directive in php.ini';break;case '2' :$error = 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form';break;case '3' :$error = 'The uploaded file was only partially uploaded';break;case '4' :$error = 'No file was uploaded.';break;case '6' :$error = 'Missing a temporary folder';break;case '7' :$error = 'Failed to write file to disk';break;case '8' :$error = 'File upload stopped by extension';break;case '999' :default :$error = 'No error code avaiable';}return $error;}/** * 获取上传文件信息 */public function getFileInfo(){return $this->uploadFile;}/** * 获取一个临时文件夹中的副本 */public function getATmpCopy(){if (empty($this->tmpCopy)){$this->copyFileToTmpDir();}return $this->tmpCopy;}/** * 从临时文件夹中删除副本 */private function delFromTmpDir(){$this->tmpCopy->delFile();$this->tmpCopy = null;}/** * 将文件拷贝到一个以原文件扩展名命名的临时文件 */private function copyFileToTmpDir(){if (!empty($this->tmpCopy)){//如果已经有了,删除$this->delFromTmpDir();}$orignalName = $this->getOrignalName();$pathinfo = pathinfo($orignalName);$extendName = $pathinfo['extension'];$newName = date('YmdHis').'.'.$extendName;$newPath = WEB_PATH.'tmp_file/'.$newName;$tmpPath = $this->getTmpFilePath();copy($tmpPath, $newPath);$TmpFile = new TmpFile();$TmpFile->setPath($newPath);$TmpFile->setName($orignalName);$TmpFile->setType($this->getFileType());$TmpFile->setTmpName($newName);$this->setTmpCopyFile($TmpFile);}private function setTmpCopyFile(TmpFile $TmpFile){$this->tmpCopy = $TmpFile;}/** * 获取原始文件名 */private function getOrignalName(){return $this->uploadFile['name'];}private function getFileType(){return $this->uploadFile['type'];}private function getTmpFilePath(){return $this->uploadFile['tmp_name'];}private function getError(){return $this->uploadFile['error'];}private function getFileSize(){return $this->uploadFile['size'];}}

服务器处理接收示例:

require_once WEB_PATH . 'include/util/Result.cls.php';require_once WEB_PATH . 'include/util/AjaxFileUpload.php';$Result = new Result ( true );try {//转存到本地临时文件$UploadFile = new AjaxFileUpload ( 'excel_orders_file' );$TmpFile = $UploadFile->getATmpCopy ();$TmpFile->setSysClass ( TypeFileClass::TMP_FILE );$TmpFile->setAddTime ( date ( 'Y-m-d H:i:s' ) );$TmpFile->setAddUser ( $this->user ['uid'] );$ExcelReader = new ExcelReader ( $TmpFile->getPath (), 'Sheet1' );$max = 10000;for($i = 2; $i < $max; $i ++) {//跳过第一行表头,从第二行开始处理$orderId = $ExcelReader->getCellContent ( 'A', $i );$marketAmount = $ExcelReader->getCellContent ( 'B', $i );$orderId = intval ( trim ( $orderId ) );$marketAmount = doubleval(trim($marketAmount));if (empty($orderId)){break;}}} catch ( Exception $e ) {$Result->setSuccess ( false );$Result->setMsg ( $e->getMessage () );$Result->setCode ( $e->getCode () );}echo $Result->toJSON ();return;

临时文件类TmpFile封装:

<?phprequire_once ('include/util/File.cls.php');/**  * @author jixiaolong *  *  */class TmpFile extends File {private $tmpName;/** *  */public function __construct() {parent::__construct ();}/** *  */function __destruct() {}/** * @return the $tmpName */public function getTmpName() {return $this->tmpName;}/** * @param field_type $tmpName */public function setTmpName($tmpName) {$this->tmpName = $tmpName;}}

文件类File封装:

<?php/**  * @author jixiaolong * 文件处理类 *  */require_once WEB_PATH . 'core/dao/FileDao.cls.php';require_once WEB_PATH.'include/util/FileInterface.cls.php';class File implements FileInterface{protected $name;protected $type;protected $addTime;protected $addUser;protected $sysClass;protected $path;protected $fileDao;function __construct() {$this->name = '';$this->type = '';$this->addTime = '0000-00-00 00:00:00';$this->addUser = 0;$this->sysClass = 0;$this->path = '';$this->fileDao = new FileDao ();}/** *  */function __destruct() {}/** * @return the $name */public function getName() {return $this->name;}/** * @return the $type */public function getType() {return $this->type;}/** * @return the $addTime */public function getAddTime() {return $this->addTime;}/** * @return the $addUser */public function getAddUser() {return $this->addUser;}/** * @return the $sysClass */public function getSysClass() {return $this->sysClass;}/** * @return the $path */public function getPath() {return $this->path;}/** * @param field_type $name */public function setName($name) {$this->name = $name;}/** * @param field_type $type */public function setType($type) {$this->type = $type;}/** * @param field_type $addTime */public function setAddTime($addTime) {$this->addTime = $addTime;}/** * @param field_type $addUser */public function setAddUser($addUser) {$this->addUser = $addUser;}/** * @param field_type $sysClass */public function setSysClass($sysClass) {$this->sysClass = $sysClass;}/** * @param field_type $path */public function setPath($path) {$this->path = $path;}public function addDBRecord() {$arr = array ( 'sys_class' => $this->sysClass, 'name' => $this->name, 'type' => $this->type, 'path' => $this->path, 'add_time' => $this->addTime, 'add_user' => $this->addUser );$this->fileDao->doAdd ( $arr );}public function delFile(){if (!empty($this->path)){$res = preg_match('/^http/', $this->path);if (empty($res)){@unlink($this->path);}}}/** * 获取文件链接 * @return string html形式的文件链接 */public function getLink(){return "<a href='{$this->getPath()}'>{$this->getName()}</a>";}}

文件接口封装:

<?phpinterface FileInterface {public function getName();public function getType();public function getAddTime();public function getAddUser();public function getSysClass();public function getPath();public function setName($name);public function setType($type);public function setAddTime($addTime);public function setAddUser($addUser);public function setSysClass($sysClass);public function setPath($path);public function addDBRecord();public function delFile();}
