thinkphp和uploadfiy

上传页面 用的是bootstrap

<div class="col-sm-6">
<div style="width: 200px; height: 110px; float: left;">
<input type="hidden" name="photo" value="" id="data_photo" />
<input id="photo_file" name="photo_file" type="file" multiple="true" value="" />
</div>
<div style="height: 110px; float: left;">
<img id="upload_img" src="" onerror="this.src='__PUBLIC__/Admin/img/no_img.jpg'" style="height: 100px" />
</div>
</div>

$(function(){

$('#photo_file').uploadify({
'swf' :'__PUBLIC__/admin/swf/uploadify.swf',  //swf的相对路径
'uploader': '{:U("Upload/upload")}',　　//后台处理
'buttonText': '上传头像', //按钮
'height': 35,  //高度
'fileTypeExts': '*.gif;*.jpg;*.png',  //上传类型
'queueSizeLimit': 1,
'onUploadSuccess': function(file, data, response) {

$("#upload_img").attr('src', '__PUBLIC__/Uploads/adminimg/' + data);  //预览效果
$("#data_photo").val(data);
}
});
});

详细的 http://www.cnblogs.com/mofish/archive/2012/11/30/2796698.html 这个非常不错

public function upload(){
$upload = new \Think\Upload();// ʵ�����ϴ���
$upload->maxSize   =     3145728 ;// ���ø����ϴ���С
$upload->exts      =     array('jpg', 'gif', 'png', 'jpeg');// ���ø����ϴ�����
$upload->rootPath  =     './Public/Uploads/adminimg/'; // ���ø����ϴ���Ŀ¼
$upload->savePath  =     ''; // ���ø����ϴ����ӣ�Ŀ¼
// �ϴ��ļ�
$info   =   $upload->upload();
if(!$info) {// �ϴ�������ʾ������Ϣ
$this->error($upload->getError());
}else{// �ϴ��ɹ�
foreach($info as $file){
echo $file['savepath'].$file['savename'];
}
}
