The TwigInjectionBundle allows to inject twig templates through the event behavior.
TwigInjectionBundle requires Symfony 2.8 or higher.
Require the bundle in your composer.json file:
{
"require": {
"intaro/twig-injection-bundle": "~1.0.0",
}
}
```
Register the bundle in `AppKernel`:
```php
// app/AppKernel.php
public function registerBundles()
{
$bundles = array(
//...
new Intaro\TwigInjectionBundle\IntaroTwigInjectionBundle(),
);
//...
}
```
Install the bundle:
```
$ composer update intaro/twig-injection-bundle
```
## Usage
1) Add `{{ inject() }}` calling in template:
```twig
{{ inject('twig.injection.event.name', { parameter1: 'some-value', parameter2: some_object }) }}
```
2) Prepare controller action which you want to render or template which you want to include.
3) Define Listener which will inject `include` or `render` calling:
```php
<?php
namespace Acme\DemoBundle\EventListener;
use Intaro\TwigInjectionBundle\Event\TwigInjectEvent;
use Intaro\TwigInjectionBundle\Event\TwigInjectRender;
class TwigInjectionListener
{
public function onSomeEvent(TwigInjectEvent $event)
{
$parameters = $event->getParameters();
if (!isset($parameters['parameter1']) || 'some-value' !== $parameters['parameters1']) {
return;
}
$render = new TwigInjectRender(
'AcmeDemoBundle:DefaultController:index',
[ 'object' => $parameters['parameters2'] ]
);
$event->addInjection($render);
$include = new TwigInjectInclude('AcmeDemoBundle:Default:someTemplate.html.twig');
$event->addInjection($include);
}
}
```
4) Register the listener:
```yaml
services:
acme_demo.twig_injection.listener:
class: Acme\DemoBundle\EventListener\TwigInjectionListener
tags:
- { name: kernel.event_listener, event: twig.injection.event.name, method: onSomeEvent }
```
