Download the PHP package seiffert/controller-helper-bundle without Composer

SeiffertControllerHelperBundle

This bundle provides simple helpers for Symfony2 controllers.

Setup

Require the package via composer:

composer.json:

    "require": {
        ...
        "seiffert/controller-helper-bundle": "dev-master",
        ...
    }

Activate the bundle in your AppKernel:

Note: SeiffertHelperBundle has to be registered as well, since SeiffertControllerHelperBundle uses it as a dependency.

app/AppKernel.php:

    public function registerBundles()
    {
        $bundles = array(
            ...
            new Seiffert\HelperBundle\SeiffertHelperBundle(),
            new Seiffert\ControllerHelperBundle\SeiffertControllerHelperBundle(),
            ...
        );
        ...
    }

Usage

The purpose of this bundle is to provide helper methods for controllers that have been specified as services. To avoid these controller having tons of dependencies, this bundle groups all those helpers a controller needs, and provides a single object which has all necessary helper methods. This helper object can be injected into your controllers like this:

services.yml:

...
my.bundle.controller.default:
    class: %my.bundle.controller.default.class%
    arguments:
        - @seiffert.helper.controller

My\Bundle\Controller\DefaultController.php:

<?php

namespace My\Bundle\Controller;

class DefaultController
{
    private $h;

    public function __construct($helper)
    {
        $this->h = $helper;
    }

    public function indexAction()
    {
        return $this->h->render('MyBundle:Default:index.view.html');
    }
}
