i not know how variable in controller

in view file, in form

<?php echo '<b class="badge">$10</b> ' . slider::widget([     'name'=>'min_money',     'value'=>'250,650',     'slidercolor'=>slider::type_grey,     'pluginoptions'=>[         'min'=>10,         'max'=>1000,         'step'=>5,         'range'=>true     ], ]) . ' <b class="badge">$1,000</b>'; 

in controller

public function actioncreate() {     $model = new model; // give actual model name instead of model     if($model->load(yii::$app->request->post()))     {         list($model->min_money, $model->max_money) = explode(',', $model->min_money);         // both $model->min_money , $model->max_money set , contains value submitted in form kartik slider widget         if($model->save(true))         {             // success -> redirect         }         else         {             // error render form again         }      } }
