1、单个文件上传

首先建立一个模型models/UploadForm.php,内容如下

namespaceapp\models;useyii\base\Model;useyii\web\UploadedFile;/***UploadFormisthemodelbehindtheuploadform.*/classUploadFormextendsModel{/***@varUploadedFilefileattribute*/public$file;/***@returnarraythevalidationrules.*/publicfunctionrules(){return[[['file'],'file'],];}}

再建立一个视图文件，内容如下

<styletype="text/css">.bar{width:100%;height:18px;background:green;}#sucess{height:18px;color:#d76f01;font-weight:12px;display:none;}</style><divid="sucess">上传成功</div><inputtype="file"name="UploadForm[file]"id="fileupload_input"/><divid="progress"><divclass="bar"></div></div><scriptsrc="<?phpecho\common\CommFun::base_url()?>statics/saas/scm/app2_release/js/common/plugins/fileupload/js/vendor/jquery.ui.widget.js"></script><scriptsrc="<?phpecho\common\CommFun::base_url()?>statics/saas/scm/app2_release/js/common/plugins/fileupload/js/jquery.iframe-transport.js"></script><scriptsrc="<?phpecho\common\CommFun::base_url()?>statics/saas/scm/app2_release/js/common/plugins/fileupload/js/jquery.fileupload.js"></script><scripttype="text/javascript">$(function(){$("#fileupload_input").fileupload({url:"index.php?r=bill/include",//文件上传地址，当然也可以直接写在input的data-url属性内formData:{param1:"p1",param2:"p2"},//如果需要额外添加参数可以在这里添加done:function(e,result){//done方法就是上传完毕的回调函数，其他回调函数可以自行查看api//注意result要和jquery的ajax的data参数区分，这个对象包含了整个请求信息//返回的数据在result.result中，假设我们服务器返回了一个json对象if(JSON.stringify(result.result)=='"200"'){//alert('上传成功')}else{alert(JSON.stringify(result.result))}},progressall:function(e,data){//设置上传进度事件的回调函数varprogress=parseInt(data.loaded/data.total*100);$('#progress.bar').css('width',progress+'%');if(progress==100){$('#sucess').show()}}})});</script>

最后建立控制器文件，内容如下

//获取新单据号publicfunctionactionInclude(){$model=newUploadForm();if(Yii::$app->request->isPost){$model->file=UploadedFile::getInstance($model,'file');$allow=array('xls','xlsx');if($model->file&&in_array($model->file->extension,$allow)){$result=$model->file->saveAs('uploads/'.$model->file->baseName.'.'.$model->file->extension);if($result){echo'200';exit;}else{echo'上传失败';exit;}}else{echo'格式不对';exit;}}return$this->render('includeView',['model'=>$model]);}
