php - yii2 login page redirection looping with cancelled status -

-

after spending many days, trying experts. stuck login redirection in yii2 application in chrome browser,

enter image description here

this controller class,

    class invitationscontroller extends controller {     public function beforeaction($action)     {   $array=array('index','imageupload','template','category','subcategory','slug','chooseanotherdesign');         if(!in_array($action->id, $array))            {                 if (\yii::$app->getuser()->isguest &&                     \yii::$app->getrequest()->url !== url::to(\yii::$app->getuser()->loginurl)                 ) {                     \yii::$app->getresponse()->redirect(\yii::$app->getuser()->loginurl,false);                 }            }                 return parent::beforeaction($action);     }     public function actiongenerateevent(){         $redirecturl="";                 if(yii::$app->request->post()){                     unset(yii::$app->session['copyinvitation']);                     unset(yii::$app->session['eventform']);                     yii::$app->session['eventform']=yii::$app->request->post();                 }                 if (!yii::$app->user->isguest)                 {                         $eventid=$this->invitation->savecontinue(yii::$app->session['eventform']);                         $eventdata=$this->invitation->geteventbyid($eventid);                         $refurl=yii::$app->session['eventform']['refererurl'];                         $aa['events']=$eventdata;                         $aa['refererurl']=$refurl;                         yii::$app->session['eventform']=$aa;                         $redirecturl = yii::$app->urlmanager->createabsoluteurl(['invitations/event/'.$eventdata['event_token']]);                         return $this->redirect($redirecturl);                 }       } }

my workflow step1: submitting formdata controller xx-action step2: if user login proceed further action else trying store values in session redirecting page login

step 3: after successful login return same xx-action

this workflow working fine in firefox chrome it's making infinitive loop not going through login page. please refer attached screenshot

please me solve issue.

i can't infere how calling actiongenerateevent() seems have error there:

$redirecturl=""; //empty ... return $this->redirect($redirecturl); //still empty

since not setting $redirecturl, redirect redirecting current (same) url again , again, causing loop.

this function used redirecturl() method: url::to(). docs says:

an empty string: requested url returned;
