## Webuploader整合ThinkPHP上傳學習筆記
**水月居**
#### 一、在項目配置文件中增加模板配置變量
__WEBUPLOADER__=> '__WEBUPLOADER__'=> __ROOT__ . '/Public/js/ext/webuploader'
//你的webuplder所在文件位置
#### 二、upload.js 需修改項
// swf文件路徑
swf: “../Uploader.swf”//原始mode
swf: “__WEBUPLOADER__ /Uploader.swf”, //注意要加上””
server:”../uploader.php”//
server: “__CONTROLLER__/webuploader”,
也可以采用ThinkPHP3.2.3的U函數生成'{:U("webuploader ")}'
#### 三、 增加在頁面顯示圖片
在 function addFile( file ) { ....... }中添加顯示文件代碼
// 當有文件添加進來時執行，負責view的創建
~~~
var $li = $( '<li id="' + file.id + '">' +
'<p class="title">' + file.name + '</p>' +
'<p class="imgWrap"></p>'+
'<p class="progress"><span></span></p>' +
'<input type="hidden"class="up-filesname" name="image[]" >'+
'</li>' ),
$btns = $('<div class="file-panel">' +
'<span class="cancel">刪除</span>' +
'<span class="rotateRight">向右旋轉</span>' +
'<span class="rotateLeft">向左旋轉</span></div>').appendTo( $li ),
$prgress = $li.find('p.progress span'),
$wrap = $li.find( 'p.imgWrap' ),
$info = $('<p class="error"></p>'),
~~~
#### 四、上傳控制器增加返回參數tajax-return()
data返回函數如下
data=array('file_url'=>$file['savepath].$file['savename]);
~~~
$data=array();
if(!$info){
// 返回錯誤信息
$error=$upload->getError();
$data['error_info']=$error;
$data['valid']=0;
}else{
// 返回成功信息
foreach($info as $file){
$data['file_url']=trim($file['savepath'].$file['savename'],'.');
$data['valid']=1;
}
}
// echo json_encode($data);
$this->ajaxReturn($data);
~~~
#### 五、增加頁面提交文件上傳后的file_url相關信息
在 uploader.onUploadSuccess=function(file ,response){....}中添加
~~~
uploader.onUploadSuccess=function(file ,response){
alert('輸出文件是：'+ response.file_url);
$('#'+file.id +' .up-filesname').val(response.file_url);
}
~~~
