2024-09-02 08:14:16

1.js

$("input#upload").change(function () {
$.ajaxFileUpload({
url: '/members/web-members-rest/upload.html',
secureuri: false,
data:{'id':id},
fileElementId:'upload',
dataType: 'xml',
success: function (data, status) {
if ($(data).find("result").text() == 'Success') {
//上传成功
}
else{
alert("上传失败");
}
},
error: function (data, status, e) {
return;
}
});
});
$("a.upload").click(function(){$("input#upload").click();});

2.htm

<a href='javascript:;' class="upload">上传</a>
<div style="display:none"><input type="file" id="upload" name="UploadForm[file]" /></div> 这个name很重要
<img data-name="img" src="blank.gif" />

3.php,rest

public function actionUpload(){
$params=Yii::$app->request->post();
$model = new UploadForm();
if (Yii::$app->request->isPost) {
$model->file = UploadedFile::getInstance($model, 'file');
if ($model->file && $model->validate()) {
if(!file_exists('data/upload/'.$uid))mkdir('data/upload/'.$uid);
$path='data/upload/';
if(!file_exists($path))mkdir($path);
$filename=$params['id'].'.' . $model->file->extension;
if($model->file->saveAs($path.$filename))
return ["result"=>"Success","url"=>$path.$filename];
else return ["result"=>"Fail"];
}
return ["result"=>"ValidFail"];
}
return ["result"=>"PostFail"];
