Yii 2.0 General Discussions

hi community,

I have stuck in my project.

i have unique validation of email and username.

also have profile pic to upload on user creation.

usermodel:


  

[['name', 'username','email','pass','profilepic'], 'required'],

[['email','username'], 'unique', 'targetClass' => '\backend\models\User', 'message' => 'This email or username has already been taken.'],

usercontroller:

to validate unique filed i need to use $model->validate();


if ($model->load(Yii::$app->request->post()) && $model->validate()) 

{ 

}

my issue is if im using $model->validate() profilepic is get null after submitting form.

if im not using validate() unique validation is not working.

can someone please help me in this.

regards.

#sitecontroller:#

    { 

        $model = new User();

       $model->scenario = 'upload';

        if ($model->load(Yii::$app->request->post()) ) { 

            if($model->validate())

            {

                $file = UploadedFile::getInstance($model, 'profilepic');

               if($file){

                    $file->saveAs(\Yii::$app->basePath.'/web/uploads/'.$file->name);

                    $model->profilepic = $file->name; 

                    $model->save(false);

                    Yii::$app->getSession()->setFlash('success', 'Successfully registered.');

                        return $this->render('upload', [

                    'model' => $model,

                    ]);

                 }

            }

            else

            {

                echo "<pre>";

                print_r($model->geterrors());exit;

                Yii::$app->getSession()->setFlash('error', 'Error in registration.');

                    return $this->render('upload', [

                    'model' => $model,

                    ]);

            }

        }

#site/upload#




    <?php $form = ActiveForm::begin(['id' => 'form-signup',

        'type' => ActiveForm::TYPE_HORIZONTAL,

        'formConfig' => ['showErrors' => true,'showLabels' => true],

        'options' => ['enctype' => 'multipart/form-data']

      

    ]); 

             ?>

      

 <div class="form-group kv-fieldset-inline">

  <?= $form->field($model, 'profilepic')->widget(FileInput::classname(),[ 'pluginOptions' => ['showUpload' => false]]); ?>

  </div> 

                <div class="form-group">

                    <?= Html::submitButton('Signup', ['class' => 'btn btn-primary', 'name' => 'signup-button']) ?>

                </div>

            <?php ActiveForm::end(); ?>

#User Model#




public function rules()

    {

        return [

         

            ['profilepic', 'required'],

            [['profilepic'], 'required', 'on' => 'upload'],

            ['profilepic', 'file', 'extensions'=>'jpg, jpeg, png'], 


             

        ];

    }   

     public function scenarios()

    {

        

        $scenarios = parent::scenarios();


        $scenarios['upload'] = ['profilepic'];//Scenario Values Only Accepted 


        return $scenarios;


    }

validate() method is not working with file upload.

webin

I think you should call validate() (or save()) method before you call getInstance(). Look at this code, it may be helpful:




if (Yii::$app->request->isPost) {

    $model->load(Yii::$app->request->post());

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

    if ($model->validate()) {

        // do your things...

    }

}
