Message Redirect Bundle

Introduction

Symfony2 bundle that provides service for conveniently redirecting the user from wherever you are in the call stack, and displaying a message to the user.

It does this by throwing a MessageRedirectException that is then caught by the MessageRedirectListener which adds the message to the session flahsBag, andthen redirects the user to the specified URI.

If a previous exception is passed in to the MessageRedirectException, and the current environment has debugging enabled, then the exception will not trigger a redirect, and the exception will be displayed to the user, including the previous exception thrown.

Installation

To use this bundle follow these steps...

1. Add the bundle using composer

    "require": {
        "cubicmushroom/symfony-error-redirect": "dev-master"
    }
   

2. Register the bundle in app/AppKernel.php

    class AppKernel extends Kernel
    {
        // ...
   
        public function registerBundles()
        {
            $bundles = array(
                // ...
                new CubicMushroom\MessageRedirectBundle\CubicMushroomMessageRedirectBundle(),
            );
            
            // ...
    
            return $bundles;
        }
        
        // ...
    }
   

3. Add the message template to your view template (probably best at the base template level to avoid having ot remember to each view

    {{ include('CubicMushroomMessageRedirectBundle:elements:message.html.twig') }}
   

   To add your own classes to the flash messages, define the flashClasses twig variable before calling the inlude

    {% set flashClasses = 'alert' %}
    {{ include('CubicMushroomMessageRedirectBundle:elements:message.html.twig') }}
   

Usage

Redirect

There are 1 ways to rediect...

1. Use the service's createRedirectWithMessage() method and returning this from your controller.

    // If within object with a Container object
    return $this->container->get('message_redirect')->createRedirectWithMessage( $uri, $message, $messageClass );
   

2. Create and throw a RedirectMessageException

    // If within object with a Container object
    thrown $this->container->get('message_redirect')->createRedirectException(
        $uri,
        $message,          // optional
        messageType,       // optional
        $previousException // optional
    );
   

Using different Exception class to redirect

To use your own exception class for the redirects, simply set the %message_redirect.exception.message_redirect.class% parameter to another exception class that implements the \CubicMushroom\MessageRedirectBundle\Exception\MessageRedirectExceptionInterface interface

To use your own exception on for a single request, you can set the exception class on the service by doing the following...

$this->container->get('message_redirect')->setMessageRedirectExceptionClass( $class );
// Then call createRedirectWithMessage() to create the exception to throw
