这篇文章主要介绍了ThinkPHP结合AjaxFileUploader实现无刷新文件上传的方法,是ThinkPHP文件上传中一个比较典型的应用技巧,非常具有实用价值,需要的朋友可以参考下
本文实例讲述了ThinkPHP结合AjaxFileUploader实现无刷新文件上传的方法。分享给大家供大家参考。具体实现方法分析如下:
首先,AjaxFileUploader插件是一个基于jquery的插件,我们可以使用AjaxFileUploader插件来实现文件异步上传功能了,使用这款插件上传文件不要担心兼容性的问题,它的兼容性可以说兼容所有主流浏览器,下面来给大家介绍一个AjaxFileUploader+thinkphp实现文件上传的实例。
ThinkPHP框架下用AjaxFileUploader插件实现ajax文件上传,支持多种文件格式,页面无刷新上传。
在Lib/Action/目录下创建upAction.class.php文件,代码如下:
- <?php
- class upAction extends BaseAction{
- public function index(){
- $this->display();
- }
- /*
- *@文件上传
- *@author FineYi
- *@date 2013-01-23
- */
- public function upLoadFile(){
- $error = "";
- $msg = "";
- $fileElementName = 'fileToUpload';
- if(!emptyempty($_FILES[$fileElementName]['error'])){
- switch($_FILES[$fileElementName]['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:
- $error = 'No error code avaiable';
- }
- }elseif(emptyempty($_FILES['fileToUpload']['tmp_name']) || $_FILES['fileToUpload']['tmp_name'] == 'none'){
- $error = 'No file was uploaded..';
- }else{
- $re = $this->up();
- if(!$re){
- $error = 'Up file fail';
- }
- $msg = $re['savename']; //文件名
- $path = '/upload/bizcoop/'.$msg; //文件路径
- $size = $re['size']; //文件大小
- }
- echo json_encode(array('error'=>$error,'msg'=>$msg,'path'=>$path,'size'=>$size));exit;
- }
- private function up(){
- import('@.Org.UploadFile');//将上传类UploadFile.class.php拷到Lib/Org文件夹下
- $upload=new UploadFile();
- $upload->maxSize='-1';//默认为-1,不限制上传大小
- $upload->savePath= ICTSPACE_DIST_ROOT_PATH.'/www/upload/bizcoop/';//保存路径
- $upload->saveRule=uniqid;//上传文件的文件名保存规则
- $upload->uploadReplace=true;//如果存在同名文件是否进行覆盖
- $upload->allowExts=array('jpg','jpeg','png','gif');//准许上传的文件类型
- if($upload->upload()){
- $info=$upload->getUploadFileInfo();
- return $info[0];
- }else{
- return false;
- exit;
- }
- }
- }
- ?>
在/Tpl/default/Up/目录下创建index.tpl文件,代码如下:
- <div id="content">
- <h1>Ajax File Upload Demo</h1>
- <img id="loading" style="display: none;" alt="" src="__APP____PUBLIC__/style/img/loading.gif" />
- <form action="" enctype="multipart/form-data" method="POST" name="form">
- <table class="tableForm" cellspacing="0" cellpadding="0">
- <thead>
- <tr>
- <th></th>
- </tr>
- </thead>
- <tbody>
- <tr>
- <td><input class="input" id="fileToUpload" type="file" name="fileToUpload" size="45" /></td>
- </tr>
- <tr>
- <td><button class="button" id="buttonUpload" onclick="return ajaxFileUpload();">Upload</button></td>
- </tr>
- </tbody>
- <tbody>
- <tr>
- <td><span>已上传的附件:</span></td>
- </tr>
- </tbody>
- <tfoot></tfoot>
- </table>
- </form></div>
在/Lib/Org/目录下放入ThinkPHP文件上传类就可以了,有一些插件我们需要到官方下载。
希望本文所述对大家的PHP程序设计有所帮助。
