yii2 文件上传

直接贴代码了

----------------------------------------------------------------------------------------------------------

先新建一个model文件 UploadForm.php

  内容:   

namespace app\models;

use yii\base\Model;
use yii\web\UploadedFile;

/**
* UploadForm is the model behind the upload form.
*/
class UploadForm extends Model
{
/**
* @var UploadedFile file attribute
*/
public $file;

/**
* @return array the validation rules.
*/
public function rules()
{
return [
[['file'], 'file'],
];
}
}

---------------------------------------------------------------------------------------------------------------------

控制器层内容:

use app\models\UploadForm;
use yii\web\UploadedFile;

function actionIndexadv(){
$request = Yii::$app->request;
$model = new UploadForm();
if($request->isPost){
$model->file = UploadedFile::getInstance($model, 'file');
if ($model->file && $model->validate()) {
$r = $model->file->saveAs('uploads/' . $model->file->baseName . '.'. $model->file->extension);    //这是上传,uploads文件夹要自己手动创建
}
}else{
return $this->renderPartial('adv_add.html',['model' => $model]);
}
}

----------------------------------------------------------------------------------------------------------------------------

显示页面内容:

use yii\widgets\ActiveForm;
use yii\helpers\Url;
?>

['enctype' => 'multipart/form-data']]) ?>
