[FIXED] How to update uploaded file using yii2

Issue

I want to update the uploaded file using yii2. I have the codes but nothing happens. I don't know whats wrong with my codes. Help me guys.

This is my form

<?= $form->field($model, 'doc_for')->textInput(['maxlength'=>true,'style'=>'width:500px']) ?>
<?= $form->field($model, 'doc_from')->textInput(['maxlength'=>true,'style'=>'width:500px']) ?>
<?= $form->field($model, 'drawer_id')->textInput(['maxlength'=>true,'style'=>'width:500px']) ?>
<?= $form->field($model, 'doc_name')->textInput(['maxlength'=>true,'style'=>'width:500px']) ?>
<?= $form->field($model, 'doc_file')->fileInput() ?>
<div class="form-group">
    <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-primary' : 'btn btn-primary']) ?>
</div>

Model

 public function rules()
{
    return [
        [['reference_no', 'subject', 'doc_date', 'doc_for', 'drawer_id','doc_from','doc_name','doc_file'], 'required'],
        [['reference_no'], 'integer'],
        [['doc_date'], 'safe'],
        [['subject', 'doc_for', 'drawer_id','doc_from','doc_name'], 'string', 'max' => 250],
        [['doc_file'], 'file', 'skipOnEmpty' => false, 'extensions' => 'docx, docs, doc',],

    ];
}

Controller create

 public function actionCreate()
{
$model = new Documents();
if ($model->load(Yii::$app->request->post())) 
{      
        $project =$model->doc_name;
        $model->upload_file= UploadedFile::getInstance($model,'doc_file');
        $model->upload_file->saveAs('uploads/'.$project.'.'.$model->upload_file->extension);
        $model->doc_file='uploads/'.$project.'.'.$model->upload_file->extension;
        $model->save();

        Yii::$app->getSession()->setFlash('success','Data saved!');
        return $this->redirect(['view','id'=> $model->reference_no]);
        } 

        else {

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

}

Controller update

public function actionUpdate($id)
{
     $model = new Documents();
     $model = $this->findModel($id);
     $current_image = $model->doc_file;
     $project =$model->doc_name;
    if ($model->load(Yii::$app->request->post())) {         
    $model->upload_file= UploadedFile::getInstance($model,'doc_file');
    if(!empty($upload_file) && $upload_file->size !== 0) {
        //print_R($image);die;
       $model->upload_file->saveAs('uploads/'.$project.'.'.$model->upload_file->extension);
        $model->doc_file='uploads/'.$project.'.'.$model->upload_file->extension;
           $model->upload_file = $current_image;
    $model->save();


        Yii::$app->getSession()->setFlash('success','Data updated!');
        return $this->redirect(['view','id'=> $model->reference_no]);
}
} else {
    return $this->render('update', [
        'model' => $model,
    ]);
}
}

I don't know whats wrong. Any ideas?

Solution

Ok thanks for the help. I got it. Now its working properly now. This is the code.

actionUpdate Controller:

  public function actionUpdate($id)
{
    $model = $this->findModel($id);
    $current_image = $model->upload_file;
    if ($model->load(Yii::$app->request->post())) {         
    $project =$model->doc_name;
    $model->upload_file= UploadedFile::getInstance($model,'doc_file');
    if(!empty($model->upload_file) && $model->upload_file->size !== 0) {
        //print_R($image);die;
    $model->upload_file->saveAs('uploads/'.$project.'.'.$model->upload_file->extension);
    $model->doc_file='uploads/'.$project.'.'.$model->upload_file->extension;
    }
    else
    $model->upload_file = $current_image;
    $model->save();
      Yii::$app->getSession()->setFlash('success','Data updated!');
    return $this->redirect(['view', 'id' => $model->reference_no]);
} else {
    return $this->render('update', [
        'model' => $model,
    ]);
}
}
