Installation

composer require stagem/zfc-flash

In Expressive

You should enable module in config/config.php as Stagem\ZfcFlash\ConfigProvider::class and register middleware inconfig/pipeline.php

$app->pipe(\Stagem\ZfcFlash\FlashMiddleware::class);

This allow gets flash object from request as $flash = $request->getAttribute('flash');

Usage

In Expressive

use Psr\Http\Server\RequestHandlerInterface;
use Zend\Diactoros\Response\RedirectResponse;

function($request, RequestHandlerInterface $handler)
{
    $flash = $request->getAttribute('flash');
    $flash->addMessage('Hello World!', 'success');

    return new RedirectResponse('/other-middleware');
}

Out of the box this module works with Zend\View\Helper\FlashMessenger and twitter bootstrap

Include flash-messages template in your template as <?= $this->partial('widget::flash-messages') ?>

If you want change html markup or style see section Custom Flash.

Custom Flash

Be carefully, you should enable your module after Stagem\ZfcFlash\ConfigProvider::class in config/config.php

You can develop custom adapter for any Flash Messages only implement Stagem\ZfcFlash\FlashInterface and register in depenencies in your config/module.config.php

Custom template

Create new .phtml file, get messages and implement custom html markup. You can use current helper or other approach for get Request object and than get the flash.

// view/widget/flash-messages.phtml
#$flash = $this->current('request')->getAttribute('flash');
$messages = $flash->getAllMessages();
// iterate over array 

After that add your template to config/module.config.php and include in template

return [
    'templates' => [
        'paths' => [
            'widget' => [__DIR__ . '/../view/widget'],
        ],
    ],
];
