控制器：

<?php
namespace frontend\controllers;
use yii\base\Model;
use yii\web\Controller;
use yii\helpers\ArrayHelper;
use yii\helpers\FileHelper;
use common\models\Upmore;
use yii\web\UploadedFile;
use Yii;
class UpmoreController extends  Controller{
public $enableCsrfValidation = false;
    public function actionUpmore(){
        $model=new Upmore();
        if (Yii::$app->request->isPost) {
            $file = UploadedFile::getInstances($model, 'file');

            if ($file && $model->validate()) {
                

                foreach ($file as $fl) {
                    $fl->saveAs(Yii::$app->basePath."/uploads/".iconv("UTF-8", "GB2312//IGNORE", $fl->baseName). '.' . $fl->extension);
                }

                return $this->redirect('upmore');
            }
        }

        return $this->render('upmore', ['model' => $model]);
    }



}

视图：

<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
?>
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>多文件上传</title>
</head>
<body>
<?php if(Yii::$app->session->hasFlash('success')):?>
    <div class="alert alert-danger">
        <?=Yii::$app->session->getFlash('success')?>
    </div>
<?php endif ?>
<?php $form=ActiveForm::begin([
    'id'=>'upload',
    'enableAjaxValidation' => false,
    'options'=>['enctype'=>'multipart/form-data']
]);
?>
<?= $form->field($model, 'file[]')->fileInput(['multiple' => true]);?>
<?=  Html::submitButton('提交', ['class'=>'btn btn-primary','name' =>'submit-button']) ?>
<?php ActiveForm::end(); ?>

</body>
</html>

模型：

<?php

namespace common\models;

use Yii;

/**
 * This is the model class for table "upmore".
 *
 * @property integer $id
 * @property string $path
 * @property string $file
 * @property string $created_at
 */
class Upmore extends \yii\db\ActiveRecord
{     public $file;
    /**
     * @inheritdoc
     */

    public static function tableName()
    {
        return 'upmore';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
          return [
          [['file'], 'file', 'maxFiles' => 10,'extensions'=>'jpg,png,gif,txt,doc'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'path' => 'Path',
            'file' => 'File',
            'created_at' => 'Created At',
        ];
    }


}
