Symfony 在细枝模板中切换主题

我有一个功能齐全的网站与Symfony和细枝

现在我想这样做：在

src/AppBundle/Resources/views

文件夹中放置两个或多个主题，比如

theme1

和

theme2

，放在两个不同的目录下：

theme1

和

theme2

，这样我就可以以某种方式快速更改我网站的主题

我从以下位置将模板引用放在我的小树枝模板中：

return $this->render('AppBundle:default:index.html.twig'...

例如：

return $this->render('AppBundle:theme1:default:index.html.twig'...

但它不起作用：找不到模板

这方面有什么帮助吗？

我已经在我的Symfony项目中完成了这项工作，这取决于我从哪个域查看我的站点。您可能有一个不同的用例，但下面是一个我如何实现结果的示例

将以下函数添加到src/YourBundle/DependencyInjection/Configuration.php

public function getConfigTreeBuilder()
{
    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('bundle_name');

    $rootNode
            ->children()
                ->arrayNode('sites')
                ->prototype('array')
                    ->children()
                        ->scalarNode('domain')->isRequired()->cannotBeEmpty()->validate()->ifNull()->thenInValid("Domain name must be set")->end()->end()
                        ->scalarNode('template_directory')->isRequired()->cannotBeEmpty()->validate()->ifNull()->thenInValid("Template Directory must be set")->end()->end()
                    ->end()
                ->end()
            ->end()
    ;

    return $treeBuilder;
}

<?php

    namespace YourBundle\EventListener;

    use Symfony\Component\HttpKernel\Event\FilterControllerEvent;

    class TemplateListener
    {

        /** @var \Twig_Environment */
        private $twig;

        /**
         * @var array
         */
        private $hostsConfig;

        public function __construct(\Twig_Environment $twig, $hostsConfig) {
            $this->twig = $twig;
            $this->hostsConfig = $hostsConfig;
        }

        public function onKernelController(FilterControllerEvent $event) {
            $currentHost = $event->getRequest()->getHost();

            if(isset($this->hostsConfig[$currentHost])) {
                $templateDirectory = $this->hostsConfig[$currentHost]['template_directory'];    
            } else {
                $templateDirectory = 'theme1';
            }

            $this->twig->getLoader()->prependPath(dirname(__DIR__) . '/../YourBundle/Resources/views/' . $this->hostsConfig[$currentHost]['template_directory']);
        }
    }

    public function load(array $configs, ContainerBuilder $container)
    {
        //...

        $sites = array();

        //Re arrange the sites configuration to be easily accessed by domain as index
        foreach ($config['sites'] as $siteConfig) {
            $sites[$siteConfig['domain']]['template_directory'] = $siteConfig['template_directory'];
        }

        $container->setParameter('hosts.config', $sites);

        //...
    }

将bundle_name替换为您选择的名称

将以下内容添加到app/config/parameters.yml

bundle_name:
    sites:
        site1:
            domain: first-domain.tld
            template_directory: theme1
        site2:
            domain: second-domain.tld
            template_directory: theme2

您可以添加任意数量的网站，只要您有主题设置

创建一个事件监听器src/YourBundle/EventListener/TemplateListener.php

public function getConfigTreeBuilder()
{
    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('bundle_name');

    $rootNode
            ->children()
                ->arrayNode('sites')
                ->prototype('array')
                    ->children()
                        ->scalarNode('domain')->isRequired()->cannotBeEmpty()->validate()->ifNull()->thenInValid("Domain name must be set")->end()->end()
                        ->scalarNode('template_directory')->isRequired()->cannotBeEmpty()->validate()->ifNull()->thenInValid("Template Directory must be set")->end()->end()
                    ->end()
                ->end()
            ->end()
    ;

    return $treeBuilder;
}

<?php

    namespace YourBundle\EventListener;

    use Symfony\Component\HttpKernel\Event\FilterControllerEvent;

    class TemplateListener
    {

        /** @var \Twig_Environment */
        private $twig;

        /**
         * @var array
         */
        private $hostsConfig;

        public function __construct(\Twig_Environment $twig, $hostsConfig) {
            $this->twig = $twig;
            $this->hostsConfig = $hostsConfig;
        }

        public function onKernelController(FilterControllerEvent $event) {
            $currentHost = $event->getRequest()->getHost();

            if(isset($this->hostsConfig[$currentHost])) {
                $templateDirectory = $this->hostsConfig[$currentHost]['template_directory'];    
            } else {
                $templateDirectory = 'theme1';
            }

            $this->twig->getLoader()->prependPath(dirname(__DIR__) . '/../YourBundle/Resources/views/' . $this->hostsConfig[$currentHost]['template_directory']);
        }
    }

    public function load(array $configs, ContainerBuilder $container)
    {
        //...

        $sites = array();

        //Re arrange the sites configuration to be easily accessed by domain as index
        foreach ($config['sites'] as $siteConfig) {
            $sites[$siteConfig['domain']]['template_directory'] = $siteConfig['template_directory'];
        }

        $container->setParameter('hosts.config', $sites);

        //...
    }

您需要更新所有控制器（或用于渲染视图的任何控制器）

您不需要使用常规的Class:Bundle:Folder方法，只需要使用相对路径，就像您在视图/theme1（或）theme2/

return $this->render(
    'default/index.html.twig',
    array(
        ...
    )
)

这将检查
src/YourBundle/Resources/views/theme1/default/index.html.twig

或
src/YourBundle/Resources/views/theme2/default/index.html.twig

取决于您访问的域

我认为在两个冒号之后需要使用斜杠：

AppBundle:theme1:default/index.html.twig

，更深一层：

AppBundle:theme1:default/front/panel/advert.html.twig

等等。我认为在两个冒号之后需要使用斜杠：

BundleName:ActionName:TemplateName

符号在Symfony中由一个特殊的语法解析，该语法只处理只包含两个冒号的模板名称。其他一切都像往常一样处理，这意味着找不到模板。是的，就是这样。谢谢。在任何情况下，引用模板的现代推荐方法是

return$this->render（“@App/theme1/default/index.html.twig”…
