how can I upload file in php in yii2

Question

I was trying to upload pdf file from backend but I receive the following error:

Call to a member function saveAs() for uploading pdf file

My _form page

<?= $form->field($model, 'pdf_file')->fileInput(['maxlength' => true]) ?>

My controller

public function actionCreate()
{
    $model = new Bangle();

    if ($model->load(Yii::$app->request->post())) {
          // echo "<pre>";print_r($_Files['image']);exit;
          $imageName = "special_image_".rand();
          $model->image = UploadedFile::getInstance($model,'image');

          if(!empty($model->image)){          

             $model->image->saveAs('images/gold/bangle/'.$imageName.'.'.$model->image->extension);

             $model->image = $imageName.'.'.$model->image->extension;
           }

             $pdfName = "my_pdf_".rand();

           if($model->pdf_file = UploadedFile::getInstance($model,'pdf_file')){          

                $model->image->saveAs('pdf/gold/'.$pdfName.'.'.$model->pdf_file->extension);

                $model->pdf_file = $pdfName.'.'.$model->image->extension;
            }

            if($model->save(false))
            {
                return $this->redirect(['view', 'id' => $model->id]);

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

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

1) make sure your file is post by adding enctype:

<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>

2) add rule file to your rules like this:

[['imageFile'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'],

3) Get Instance for model

$model->imageFile = UploadedFile::getInstance($model, 'imageFile');

4) use saveAs

$model->imageFile->saveAs('uploads/' . $this->imageFile->baseName)
