Answer 1

You can use isGuest property from user model.

echo (Yii::$app->user->isGuest) ? '<div>Div if user is visitor</div>' : '<div>Div if user is not visitor</div>';

You can also use Rbac to manage roles and access.

if(Yii::$app->authManager->checkAccess(Yii::$app->user->id, "editor"){
    //do something
}

For hide div.I have add class in button after that hide that class instead of div

<script type="text/javascript">
 $(document).ready(function(){

    $('.btnRating').hide(); 
    $('#divliveventGallery').hide();
    var userType= document.getElementById('usertype').value;
    if(userType == 'Visitor' || userType == 'FB' || userType == 'GL') {  
      $('.btnRating').show(); 
    } else if(userType == 'Vendor'){ 
      $('.btnRating').hide();  
    } else if(userType == "") {
      $('.btnRating').hide(); 
    }
});
**************Button html**************
 echo '<button type="button" id="btnRate" onClick="rateDetail('.$dp['ven_id'].','.$userId.');" class=" btnRating btn btn-default btn-block" data-toggle="modal" data-target="#rcrate">';
             echo '<strong>Rate</strong>';
             echo '</button> ';

</script>
