Jquery插件(uploadify插件实现多文件上传）

前台HTML代码：javascript

<div class="control-group" id="title-control-group">
<label class="control-label"><?=_('关于图片(*)')?></label>
<div class="controls">                                
 <div><input id="about_file_upload" name="about_file_upload" type="file" />
 <input type="button" value="肯定上传" onclick="javascript:$('#about_file_upload').uploadify('upload','*');">&nbsp;&nbsp; ||&nbsp;&nbsp;<a href="javascript:ClearUpload('about');"><?=_('清除上传列表')?></a></div>
 <p style="color:red;"><?php $msg=_('请按如下语言版本上传:'); for($n=0;$n<count($lang);$n++) { $t.=$lang[$n]['lang'].','; } $t=substr($t,0,strlen($t)-1); echo $msg.$t; ?></p>
 <span id="about_FileNames"></span>
 <input type="hidden" name="about_images" id="about_images"/>
 <input type="hidden" name="temp_about_images" id="temp_about_images"/></div></div></div>
<script src="/theme/<?=T_D?>/assets/uploadify/jquery.uploadify.min.js" type="text/javascript" ></script>
<link href="/theme/<?=T_D?>/assets/uploadify/uploadify.css" rel="stylesheet" type="text/css" />

前台JS:php

$("#about_file_upload").uploadify({ 'swf': '/theme/<?=T_D?>/assets/uploadify/uploadify.swf',//所须要的flash文件
    'cancelImg': 'cancel.png',//单个取消上传的图片
    'auto'    : false, 'uploader': '/management/common/uploadify',//实现上传的程序
     'folder': 'uploads/pic',//服务端的上传目录
    'multi': true,//是否多文件上传的
     'displayData': 'speed',//进度条的显示方式
     'fileTypeExts': '*.jpg;*.jpeg;*.gif;*.png',//可上传的文件类型
     'fileSizeLimit': '2MB',//限制文件大小
     'simUploadLimit' :3, //并发上传数据
     'queueSizeLimit' :<?php echo count($lang);?>, //可上传的文件个数
     'buttonText' :'<?=_('文件上传')?>',//经过文字替换钮扣上的文字
     'buttonImg': 'css/images/browseBtn.png',//替换上传钮扣
     'width': 80,//buttonImg的大小
     'height': 24,//       'formData':{'source':'doctor'}, onSWFReady:function(){ $("#doctors_FileNames").html(''); $("#temp_doctor_images").val(''); }, onUploadSuccess: function (file, data, response) { var msg=$("#about_FileNames").html(); var image_data=$("#temp_about_images").val(); msg+=data+","+"<br/>"; image_data+=data+","; $("#about_FileNames").html(msg); $("#temp_about_images").val(image_data); }, onQueueComplete:function() { var msg=$("#about_FileNames").html(); var image_data=$("#temp_about_images").val(); $("#about_images").val(image_data); } }); }); //清除上传
 function ClearUpload(source) { if(source=='doctor') { $('#doctor_file_upload').uploadify('cancel','*'); $("#doctors_FileNames").html(''); $("#doctor_images").val(''); $("#temp_doctor_images").val(''); } else if(source=='about') { $('#about_file_upload').uploadify('cancel','*'); $("#about_FileNames").html(''); $("#about_images").val(''); $("#temp_about_images").val(''); } }

后端PHP代码：css

//文件上传
    function uploadify() { $sub=$this->input->post(); if(!empty($_FILES)) { $source=$sub['source']; $year=date("Y",time()); $month=date("n",time()); $day=date("j",time()); $ext=end(explode('.', $_FILES["Filedata"]["name"])); $_dir = "./uploads/$source/$year/$month/$day/"; if (!is_dir($his_dir)) { $this->commfunctions->mkpath($_dir); } move_uploaded_file($_FILES["Filedata"]["tmp_name"],$_dir.md5(time()).'_'.md5($_FILES["Filedata"]["name"]).'.'.$ext); echo "/uploads/$source/$year/$month/$day/".md5(time()).'_'.md5($_FILES["Filedata"]["name"]).'.'.$ext; } }
