Zend\View\Helper\FlashMessenger isn't compatible with Expressive

[weierophinney]

In our project, we use Zend\Expressive as core and Zend\View as template engine. And we come across with an issue that FlashMessenger only works with Zend\Mvc\Controller\Plugin\FlashMessenger or Zend\Mvc\Plugin\FlashMessenger\FlashMessenger. None of them is available in Expressive and add dependencies on Zend\Mvc isn't a good idea.

There are different Flash implementations and will be great that Zend\View\Helper\FlashMessenger depend on some FlashInterface instead of Zend\Mvc\Plugin\FlashMessenger\FlashMessenger. This feature will allow integrating Zend\View\Helper\FlashMessenger with many Flash Messanger libraries.

I've written a module for this but for now FlashInterface is dirty and require improvement.

@popovserhii Have you seen https://github.com/zendframework/zend-expressive-flash ?

@webimpress Yes, but this module isn't working correctly.
The problem is not in zend-expressive-flash but in zend-expressive-session-ext.

Аfter composer require zendframework/zend-expressive-flash and modifying config/pipeline.php, authorization to my admin stops working. I was trying to understand but everything is very confusing. That why I've created a custom module.

But even if zend-expressive-flash will work I will not be able to use a flashMessanger helper which helps renders html markup.

the zend-expressive-flash should work, I created a blog post about it some time ago https://samsonasik.wordpress.com/2018/02/11/using-view-helper-for-accessing-zend-expressive-flash-messages-in-expressive-3/

There is mezzio-flash for that https://github.com/mezzio/mezzio-flash . You can create a view helper to retrieve it. I'm closing it.

@samsonasik

I think you missed the reason of this feature request: the view helper should come from the framework. It is very annoying that I have to create it myself in every application.

I'm closing it.

Please do not close issue reports if there are added to active projects. Thanks!

@froschdesign ah, ok, just see the label, thank you ;)

@samsonasik
No problem, here are so many labels and other linked objects. 😃

There is a good chance that the helper is not added to this component but the basic problem must be tracked and solved. The same problem affects the Identity helper because the helper also does not work in a Mezzio application and there is no alternative helper.
