创建一个 models/UploadForm.php:
<?phpnamespace 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'],];}}视图文件
<?phpuse yii\widgets\ActiveForm;?><?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?><?= $form->field($model, 'file')->fileInput() ?><button>Submit</button><?php ActiveForm::end() ?>控制器
<?phpuse app\models\UploadForm;use yii\web\UploadedFile;public function actionUpload(){$model = new UploadForm();if (\Yii::$app->request->isPost) {$model->file = UploadedFile::getInstance($model, 'file');if ($model->file && $model->validate()) {$model->file->saveAs('uploads/' . $model->file->baseName . '.' . $model->file->extension);}}return $this->render('upload', ['model' => $model]);}
