Problem using setflash

Hello

I’m trying to use setFlash but I have a problem, I created a class helper. I tried it:

Helper class:




<?php

namespace yii\helpers;

use Yii;


class Utils {

    function showMsgFlashes($getFlashes) {


        if ($getFlashes !== null) {

            foreach ($getFlashes as $tipo => $msg) {


                //Gerenciando os icones de acordo com o tipo de mensagem

                switch ($tipo) {


                    case 'danger':

                        $icone = '<span class="glyphicon glyphicon-remove"></span>';

                        break;


                    case 'success':

                        $icone = '<span class="glyphicon glyphicon-ok"></span>';

                        break;


                    case 'info':

                        $icone = '<span class="glyphicon glyphicon-info-sign"></span>';

                        break;


                    case 'warning':

                        $icone = '<span class="glyphicon glyphicon-warning-sign"></span>';

                        break;


                    default:

                        $icone = '<span class="glyphicon glyphicon-asterisk"></span>';

                        break;

                }


                return '<div class="alert alert-' . $tipo . '">' . $icone . ' ' . $msg . '<button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button> </div>';

            }

        } else {


            return false;

        }

    }

}

Action on controller:




public function actionAdd(){

        

        .....

         if($model->save())

                return $this->redirect ('index');

        }

        if($qtd_model <4)

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

        else

        {

            Yii::$app->session->setFlash('danger', 'Error to save);

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

        }

            

    }

index.php:




 <?php if (Yii::$app->session->hasFlash('danger')): ?>

        <?= yii\helpers\Utils::showMsgFlashes(Yii::$app->session->getAllFlashes()) ?>

 <?php endif; ?>

I had this error:

How can I fix it?

Problem solved, I need to put static in my function:




<?php

namespace yii\helpers;

use Yii;


class Utils {

    public static function showMsgFlashes($getFlashes) {


        if ($getFlashes !== null) {

            foreach ($getFlashes as $tipo => $msg) {


                //Gerenciando os icones de acordo com o tipo de mensagem

                switch ($tipo) {


                    case 'danger':

                        $icone = '<span class="glyphicon glyphicon-remove"></span>';

                        break;


                    case 'success':

                        $icone = '<span class="glyphicon glyphicon-ok"></span>';

                        break;


                    case 'info':

                        $icone = '<span class="glyphicon glyphicon-info-sign"></span>';

                        break;


                    case 'warning':

                        $icone = '<span class="glyphicon glyphicon-warning-sign"></span>';

                        break;


                    default:

                        $icone = '<span class="glyphicon glyphicon-asterisk"></span>';

                        break;

                }


                return '<div class="alert alert-' . $tipo . '">' . $icone . ' ' . $msg . '<button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button> </div>';

            }

        } else {


            return false;

        }

    }

}
