如何将通用模型添加到 Twig 和 Slim4 [英] How to add common model to Twig and Slim4

问题描述

我将 Twig 和 Slim4 与 DI 容器一起使用(与本教程相同:https://odan.github.io/2019/11/05/slim4-tutorial.html).我想知道如何将通用模型添加到我所有的树枝视图中，例如用户对象、常规选项等.

I'm using Twig and Slim4 with DI container (the same as this tutorial: https://odan.github.io/2019/11/05/slim4-tutorial.html). I would like to know how can I add a common model to all my twig views, for example user object, general options and something like this.

这是容器 Twig 初始化:

This is the container Twig initialization:

TwigMiddleware::class => function (ContainerInterface $container) {
    return TwigMiddleware::createFromContainer($container->get(App::class), Twig::class);
},

// Twig templates
Twig::class => function (ContainerInterface $container) {
    $config = $container->get(Configuration::class);
    $twigSettings = $config->getArray('twig');        
    $twig = Twig::create($twigSettings['path'], $twigSettings['settings']);
    return $twig;
},

twig 中间件是 Slim 标准的中间件:Slim\Views\TwigMiddleware

The twig middleware is the Slim standard one: Slim\Views\TwigMiddleware

推荐答案

您可以将全局变量添加到 Twig 环境中，以便在所有模板文件中都可以访问它们:

You can add global variables to Twig environment, so they are accessible in all template files:

(为了能够提供示例代码，我假设您已经定义了一个像 user-authentication-service 这样能够解析当前用户的服务)

(To be able to provide a sample code, I assumed you have defined a service like user-authentication-service which is capable of resolving current user)

// Twig templates
Twig::class => function (ContainerInterface $container) {
    //...        
    $twig = Twig::create($twigSettings['path'], $twigSettings['settings']);
    $twig->getEnvironment()->addGlobal(
        'general_settings',
        [
            'site_name' => 'my personal website',
            'contact_info' => '[e-mail]'
        ]);
    $twig->getEnvironment()->addGlobal(
        'current_user',
        // assuming this returns current user
        $container->get('user-authentication-service')->getCurrentUser()
    );
    return $twig;
},

现在您可以访问所有模板文件中的 general_settings 和 current_user.

Now you have access to general_settings and current_user in all of your template files.
