My problem is that when I call flash messenger plugin in my controller, it works. But the same message appears when I open an another page.  
I would like to know how to avoid it?

What does it mean that it works? Is there a redirection that leads to a new HTTP request or will the current messages be rendered in the same request?

Thank you @froschdesign ,  
Let me post a sample of my code to explain to be most clear

Here is for instance in my controller ab action :

```auto
public function listeDesClassesAction()
    {    
        
        $post=$this->post;  
        $mapperClasse = $this->SM->get('TCLASSE'); 
        $hydrator = new ArraySerializableHydrator();
        $classe = new \Commun\Model\Entity\Classe();
        
        $form = $this->formManager->get(\Admin\Form\Parametrage\ClasseForm::class);              
        $form->bind($classe)->setInputFilter($classe->getInputFilter())->setData($post);           
        if(!$post){
            return new ViewModel(['form' => $form,'user' => $this->user]);
        }        
        
        if(isset($post['enregistrer'])){    
            if(!$form->isValid()){
                $this->FLASH()->showMessage($this->TRANSLATOR()->translate('form-contient-donnees-erronees'),'danger');
                return new ViewModel(['form' => $form,'user' => $this->user]);
            }
            $mapperClasse->beginTransaction(); 
            try{                   
                $data = $hydrator->extract($classe);
                $additionnalData = [
                    'dateSaisie' => date('Y-m-d H:i:s'),
                    'idRefUtilisateur' => $this->user->getIdRefUtilisateur(),
                ];
                $mapperClasse->insert($data,$additionnalData);
                $mapperClasse->commit();
            }catch (\Exception $e){  
                $mapperClasse->rollBack(); 
                $this->FLASH()->showMessage($this->TRANSLATOR()->translate($e->getMessage()),'danger');                                               
                return new ViewModel(['form' => $form,'user' => $this->user]);
            }    
            $this->FLASH()->showMessage($this->TRANSLATOR()->translate('form-successful'));
            return $this->redirect()->toRoute('administration-parametrage', ['action' => 'liste-des-classes']);
        }
                
    }

```

The code for redirection is

```auto
$this->FLASH()->showMessage($this->TRANSLATOR()->translate('form-successful'));
return $this->redirect()->toRoute('administration-parametrage', ['action' => 'liste-des-classes']);

```

Here is my view liste-des-classes.phtml;

```auto
<?php
/**
 *
 * @module Application
 * @subpackage View

$this->headTitle($this->translate('Administration - '.$this->translate('liste-des-classes-title')));
echo $this->partial('partial/commun/header-datatable');
$form->setAttribute('action', $this->url('administration-parametrage', ['action' => 'liste-des-classes']));
$form->prepare();
$classeForm = $form->get('ClasseForm');
?>

    </div>  
    <?=$this->form()->closeTag();?>
    
</div>

```

The partial view-header.phtml

```auto
<?php if(isset($this->titre)): ?>
<div class="row">
    <div class="col-12">
        <div class="page-title-box d-sm-flex align-items-center justify-content-between">
            <h4 class="mb-sm-0 font-size-18"><?=$this->titre?></h4>
        </div>
    </div>
    <?php if(isset($this->description)): ?>
    <div class="col-12">
        <div class="page-title-box d-sm-flex align-items-center justify-content-between">
            <p class="description-title"><?=$this->description?></p>
        </div>
    </div>
    <?php endif; ?>
</div>
<?php endif; ?>
<?php if($this->flash_redirect): ?>
    <?= $this->flashMessenger()->renderCurrent('default', [], false);?>
<?php endif; ?>

```

Here are my codes blocks

What I’m trying to do is :

When I post the form and process it in the controller, the successful message is shown clearly. And when for instance I refresh the page, the message still appear. When a try again the message now disapear.

You use a custom controller plugin with a custom flash messenger. The original flash messenger [sets (by default) an expiration hops of 1 for the session container](https://github.com/laminas/laminas-mvc-plugin-flashmessenger/blob/795ed4b76265498e6ee8ff2358a36db0fdae3bfa/src/FlashMessenger.php#L149-L157), so that the messages are not transported further than to the next request. Maybe your implementation is different.

And you use `renderCurrent` in your view script for messages that come from the previous request, but the method is intended for [fetching messages from the current request](https://docs.laminas.dev/laminas-mvc-plugin-flashmessenger/controller-plugin/#available-methods).

_(And please reduce your code snippets, there is just too much that is off topic. Then it will be easier to help. Thanks!)_
