README

Allow effective content injection before the app sends the response to the client.

It uses a global subscriber which will inject content from collected InjectorCommands when kernel.response event is fired. The InjectorCommands can be a simple callable returning a string or be as complex as a rendered twig template with data.

The bundle provides helpers to inject simple text, twig templates and FormView aware commands.

Install

composer require cethyworks/content-injector-bundle

AppKernel.php

class AppKernel extends Kernel
{
	registerBundles()
	{
		return [
			// ...
			new Cethyworks\ContentInjectorBundle\CethyworksContentInjectorBundle()
		];
	}
}

How to use

The global subscriber is configured out of the box.

You just need to register one or more InjectorCommand :

$subscriber = $container->get(ContentInjectorSubscriber::class);
$subscriber->regiterCommand(function(){ return 'inject_me'; });

With twig template

$commandHandler = $container->get(TwigCommandHandler::class);
$commandHandler->registerCommand('@AppBundle\Resources/assets/twig/foo.html.twig', ['foo' => 'bar']);

With FormType

The bundle provides a TypeExtension "extending" FormType (virtually all forms) adding a injector option allowing the configuration of an injector aware of the FormType's FormView. It ca be used like this :

AppInjectJsType.php

class AppInjectJsType extends AbstractType
{
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'injector' => [ 
            	'template' => '@AppBundle/Resources/assets/twig/app_inject_js_type.html.twig' ]
        ));
    }

    public function getBlockPrefix()
    {
        return 'my_form_id';
    }

    public function getParent()
    {
        return EntityType::class;
    }
}

app_inject_js_type.html.twig

<script>
    var formId = "{{ form_view.vars['id'] }}";

    // do something to your form
</script>

What's in the box ?

EventSubscriber

Twig Command, render $template with $data.

FormExtension

• Cethyworks\ContentInjectorBundle\Form\Extension\InjectorAwareTypeExtension($commandFactory, $responseSubscriber)

Enable the injector form option.

@see section How to / With Form" ""Type above.

Factories

• Cethyworks\ContentInjectorBundle\Command\Factory\TwigFormCommandFactory

Used internally by InjectorAwareTypeExtension, create TwigCommands aware of FormView.

Injectors
