CI(2.2) 配置 jquery的上传插件Uploadify(v3.2) 上传文件

1、下载uploadify,   我的是v3.2

2、模板页面引入：

<base href='{base_url()}' />
<script type="text/javascript" src="/public/admin/js/jquery.js"></script>
<script type="text/javascript" src="/public/js/ajaxfileupload.js"></script>
<script type="text/javascript" src="/public/js/uploadify/jquery.uploadify.min.js"></script>
<link rel="stylesheet" type="text/css" href="/public/js/uploadify/uploadify.css" />

3、模板页面使用：

<tr>
    <td style="text-align:center;padding-top:10px;"><span class="red"> * </span>上传并扫描应用：</td>
    <td>
        <input id="uploadApk" name="uploaApk" type="file" />
        <span id="upload_note">
            {if $edit}<font color='red'>已上传应用“{$apply['name']}”&nbsp; </font>{else}<font color='red'>建议应用包100M以内</font>{/if}
        </span>
    </td>
            
</tr>

4、js code:

<script>
window.apk_uploading_flag = 0;
$(function() {
    var seid = '{$seid}' ;
    var type = '' ;
    var vid = "{$apply['vid']}";
    $("#uploadApk").uploadify({
        height        : 30,
        swf           : '/public/js/uploadify/uploadify.swf',//Uploadify 自带的flash
        uploader      : '/admin/ajaxSelfUpload',//ajax提交页面
        width         : 120,
        buttonText    : '上传应用',
        method        : 'post',
        debug         : false,
        fileTypeExts  : '*.apk',
        sizeLimit     : 512000,        
        fileObjName   : 'uploadApk',
        progressData  : 'speed' ,
        formData      : { 'session_tmp': '' },
        onUploadStart:function(){
                window.apk_uploading_flag = 1;  
                $("#uploadApk").uploadify('settings','formData',{ 'session': seid});
        },
        onUploadComplete:function(){
                window.apk_uploading_flag = 0;
        },        
        onUploadSuccess:function(file,data,response){
            var data = JSON.parse(data)
            if(data.status){
                $("#upload_note font").html('应用上传并扫描成功');
            }else{
                $("#upload_note font").html(data.info);
            }
        }
    });

</script>

5、controller中代码

1、seid取值

 $this->assign('seid', $this->input->cookie($this->config->item('cookie_prefix') . $this->config->item('sess_cookie_name')));

 

2、上传函数

        /**
         * 上传应用本身并扫描
         */
        public function ajaxSelfUpload() {
                
                $strError = '';
                $this->load->library("MyUpload");//上传类
                $tmpFile = $_FILES['uploadApk'];
                $editId = $this->input->get('vid');
                $apkSize = $tmpFile['size'];
                $apkName = $tmpFile['name'];
                //判断文件格式、大小、判断包名是否已经存在
                //通过aapt获得apk的所有信息，将上传的apk解压到临时目录
                $upload = new MyUpload($tmpFile);
                $upload->setFileExt(array('apk'));
                $upload->setMaxsize(1024 * 1024 * 500);

                //reset upload path with category  
                $uploadApkDir = $this->getSelfUploadDir();
                $upload->setUploadPath($uploadApkDir);
                if (!$upload->isAllowedTypes()) {
                        $strError = '上传文件不是有效的apk文件';
                } elseif ($upload->isBigerThanMaxSize()) {
                        $strError = '上传文件最大不能超过 ' . intval($upload->getMaxsize() / 1024) . 'KB';
                }

                //保证上传的生成的文件唯一而不覆盖其他文件
                if (empty($strError) and $upload->upload(false, FALSE)) {

                        $uploadApkFilePath = $upload->getUplodedFilePath();
                        $this->load->library('ParseApkInfo');
                        $ParseApkInfo = new ParseApkInfo($uploadApkFilePath);
                        $apkInfoArray = $ParseApkInfo->getApkMoreInfo();

                        if (!$ParseApkInfo->getErrorMessage() && $apkInfoArray) {

                                $apkInfoArray['icon'] = $ParseApkInfo->createApkIcon('/auto/apply/img/', '/auto/apply/img/');
                                if (!$ParseApkInfo->getErrorMessage()) {
                                        $apkInfoArray['size'] = $apkSize;
                                        $apkInfoArray['size_mb'] = round($apkSize / 1024 / 1024, 2);
                                        $apkInfoArray['apk'] = ToolsHelper::getFileAccessUrl($uploadApkFilePath);
                                        $apkInfoArray['icon_url'] = ToolsHelper::getFileAccessUrl($apkInfoArray['icon']);
                                        ajaxReturn("OK", true, $apkInfoArray);
                                }
                        }
                        ajaxReturn($ParseApkInfo->getErrorMessage(), false);
                } else {
                        ajaxReturn($strError, false);
                }
        }
        
        /**
         * 应用apk包存放目录
         * @return string
         */
        private function getSelfUploadDir() {
                return ToolsHelper::getSelfUploadDir();
        }

基本配置完成，但是由于是在管理后台上传文件，所以flash 没有上传session需要手工配置下CI（uploadify配置本身简单，就是再配置后台登录上传的session的时候我花费了很长 时间所以跟大家分享出来）

修改system\libraries下面的Session.php文件：

修改sess_read函数：修改了2处

  1 function sess_read()
  2     {
  3         // Fetch the cookie
  4         //$session = $this->CI->input->cookie($this->sess_cookie_name);
  5         //为了能够在各大浏览器支持falsh上传文件，对140行处进行以下修改  （修改第一处）
  6         if($this->CI->input->post('session_tmp')){
  7              $session = $this->CI->input->post('session_tmp');
  8          }else{
  9              $session = $this->CI->input->cookie($this->sess_cookie_name);
 10          }
 11          //修改结束
 12             
 13         // No cookie?  Goodbye cruel world!...
 14         if ($session === FALSE)
 15         {
 16             log_message('debug', 'A session cookie was not found.');
 17             return FALSE;
 18         }
 19
