TwigInjectionBundle 允许通过事件行为注入 Twig 模板。

安装

TwigInjectionBundle 需要 Symfony 3.4 或更高版本。

在 composer.json 文件中要求此包

{
    "require": {
        "intaro/twig-injection-bundle": "^2.0"
    }
}

在 AppKernel 中注册包

// app/AppKernel.php

public function registerBundles()
{
    $bundles = [
        //...

        new Intaro\TwigInjectionBundle\IntaroTwigInjectionBundle(),
    ];

    //...
}

安装包

$ composer update intaro/twig-injection-bundle

使用方法

1. 在模板中添加 {{ inject() }} 调用

{{ inject('twig.injection.event.name', { parameter1: 'some-value', parameter2: some_object }) }}

1. 准备您想渲染的控制器动作或您想包含的模板

2. 定义将注入 include 或 render 调用的监听器

<?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);
    }
}

1. 注册监听器

services:
    acme_demo.twig_injection.listener:
        class: Acme\DemoBundle\EventListener\TwigInjectionListener
        tags:
            - { name: kernel.event_listener, event: twig.injection.event.name, method: onSomeEvent }
