Twig 链接到当前路线但更改语言环境

Question

我会在现有网站中添加一些指向不同区域设置版本的链接。它工作得很好，但它很丑^^

<li>
    <a href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')|merge(app.request.query.all|merge({_locale: 'es'}))) }}">
       <img src="{{ asset('img/flags/es.jpg') }}" alt="es">
    </a>
</li>
<li>
    <a href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')|merge(app.request.query.all|merge({_locale: 'fr'}))) }}">
       <img src="{{ asset('img/flags/fr.jpg') }}" alt="fr">
    </a>
</li>

你有更好的想法吗？

Answer 1

您可能需要在许多页面 and/or 不止一个项目中使用它。根据我在某些方面使用的方法，这是一种可能的方法：

# app/config/config.yml

# ...
parameters:
    # ...
    app_locales: [en, es, fr]

twig:
    # ...
    globals:
        locales: %app_locales%
        # ...

然后是旗帜模板：

{# app/Resources/views/includes/_flags.html.twig #}

{% set route = app.request.attributes.get('_route') %}
{% set route_params = app.request.attributes.get('_route_params') %}
{% set params = route_params|merge(app.request.query.all) %}

{# You may want to not print a flag/link for current view, the "if" here let you handle it #}

{% for locale in locales if locale != app.request.locale %}

    <li>
        <a href="{{ path(route, params|merge({ _locale: locale })) }}">
            <img src="{{ asset('img/flags/' ~ locale ~ '.jpg') }}" alt="{{ locale }}">
        </a>
    </li>

{% endfor %}

最终在任何视图中包含标志：

{# app/Resources/views/base.html.twig #}

{% include 'includes/_flags.html.twig' %}
