discuz中的SWFUpload使用的也就是知名的SWFUpload插件，不过好像做了一些自定义的功能。

在这我就直接说discuz中SWFUpload的使用：

显示文件PHP代码：

> require\_once libfile(‘function/upload’);  
> $swfconfig = getuploadconfig($\_G\['uid'\], 0, false);

html代码：

> <span id=”spanButtonPlaceholder”></span>  
> <script type=”text/javascript” src=”\{$\_G\[setting\]\[jspath\]\}upload.js?\{VERHASH\}”></script>  
> <script type=”text/javascript” >  
> var upload = new SWFUpload(\{  
> // Backend Settings  
> upload\_url: “\{$\_G\[siteurl\]\}train.php?mod=swfupload&ac=work”,//上传后台处理网址  
> post\_params: \{“uid” : “$\_G\[uid\]“, “hash”:”$swfconfig\[hash\]“,”lid”:”$lid”\},//传递参数
> 
> // File Upload Settings  
> file\_size\_limit : “$swfconfig\[max\]“, // 100MB  
> file\_types : “$swfconfig\[imageexts\]\[ext\]“,  
> file\_types\_description : “$swfconfig\[imageexts\]\[depict\]“,  
> file\_upload\_limit : 0,  
> file\_queue\_limit : 0,
> 
> // Event Handler Settings (all my handlers are in the Handler.js file)  
> swfupload\_preload\_handler : preLoad,  
> swfupload\_load\_failed\_handler : loadFailed,  
> file\_dialog\_start\_handler : fileDialogStart,  
> file\_queued\_handler : fileQueued,  
> file\_queue\_error\_handler : fileQueueError,  
> file\_dialog\_complete\_handler : fileDialogComplete,  
> upload\_start\_handler : uploadStart,  
> upload\_progress\_handler : uploadProgress,  
> upload\_error\_handler : uploadError,  
> upload\_success\_handler : trainUploadSuccess,//上传成功后的处理函数  
> upload\_complete\_handler : uploadComplete,
> 
> // Button Settings  
> button\_image\_url : “\{IMGDIR\}/uploadbutton.png”,//该背景图片必须是一个sprite图片,从上到下包含了Flash按钮的正常、鼠标悬停、按下、禁用这四种状态。因此该图片的高度应该是Flash按钮高度的四倍  
> button\_placeholder\_id : “spanButtonPlaceholder”,  
> button\_width: 134,  
> button\_height: 42,  
> button\_cursor:SWFUpload.CURSOR.HAND,  
> button\_window\_mode: “transparent”,
> 
> custom\_settings : \{  
> progressTarget : “imgUploadProgress”,  
> uploadSource: ‘train’,//自定义参数  
> uploadType: ‘work’,//自定义参数  
> imgBoxObj: $(‘imgattachlist’)  
> //thumbnail\_height: 400,  
> //thumbnail\_width: 400,  
> //thumbnail\_quality: 100  
> \},
> 
> // Debug Settings  
> debug: true  
> \});  
> function trainUploadSuccess(file, serverData) \{//单个文件处理函数，如果是多个请按照\{$\_G\[setting\]\[jspath\]\}upload.js的uploadSuccess进行编写  
> var data = eval(‘(‘+serverData+’)');  
> if(parseInt(data.wid)) \{  
> showDialog(‘上传成功,将跳转作业页面’, ‘right’, ‘提示信息’, function()\{window.location.href = ‘train.php?mod=work&wid=’+data.wid;\}, 0, null, ”, ”, ”, ”, 3);  
> \}else\{  
> showDialog(‘上传失败,错误代码为：’+data.errorcode+’。请联系客服QQ:\{$train\_plugin\[qq\]\}！’, ‘error’, ‘错误信息’);  
> \}
> 
> \}  
> </script>

php处理程序：

> $\_G\['uid'\] = intval($\_POST\['uid'\]);
> 
> if((empty($\_G\['uid'\]) && $\_GET\['ac'\] != ‘upload’) || $\_POST\['hash'\] != md5(substr(md5($\_G\['config'\]\['security'\]\['authkey'\]), 8).$\_G\['uid'\])) \{  
> exit();  
> \} else \{
> 
> //处理上传的文件
> 
> $\_FILES\["Filedata"\]\['name'\] = addslashes(diconv(urldecode($\_FILES\["Filedata"\]\['name'\]), ‘UTF-8′));//编码转换
> 
> //处理$\_FILES\["Filedata"\]
> 
> echo “\{\\”picid\\”:\\”0\\”, \\”url\\”:\\”0\\”, \\”bigimg\\”:\\”0\\”, \\”errorcode\\”:$errorcode\}”;//输出内容，用于js处理调用
