【中文标题】从扩展中获取当前控制器动作和 slug【英文标题】:Get current controller action and slug from extension 【发布时间】:2021-09-08 16:49:38 【问题描述】:我想选择当前网址并为菜单项添加active
类。
如何从Symfony Extensions
的当前 URL 获取控制器、动作和 slug?不在Twig
模板中,而是在扩展中。例如,我的分机是<site_root_directory>/src/Twig/AppExtensions.php
。
AppExtensions.php
:
<?php
namespace App\Twig;
use Twig\Environment;
use Twig\Extension\AbstractExtension;
use Twig\TwigFunction;
class AppExtensions extends AbstractExtension
public function getFunctions(): array
return [
new TwigFunction(
'mainMenuExtension',
[$this, 'getMainMenuWidget'],
[
'is_safe' => ['html'],
'needs_environment' => true,
]
),
];
public function getMainMenuWidget(Environment $environment)
$menu = [
['path' => 'page_home', 'title' => 'Home', 'active' => true],
['path' => 'page_categories', 'title' => 'Categories'],
['path' => 'page_category', 'title' => 'Politics', 'slug' => 'politics'],
['path' => 'page_category', 'title' => 'Business', 'slug' => 'business'],
['path' => 'page_category', 'title' => 'Health', 'slug' => 'health'],
['path' => 'page_category', 'title' => 'Design', 'slug' => 'design'],
['path' => 'page_category', 'title' => 'Sport', 'slug' => 'sport'],
['path' => 'page_about', 'title' => 'About'],
['path' => 'page_contact', 'title' => 'Contact'],
];
return $environment->render('widgets/MainMenu.html.twig', [
'menu' => $menu,
]);
【问题讨论】:
这能回答你的问题吗? How to get current route in Symfony 2? 【参考方案1】:您可以从RequestStack
服务那里获取当前的 url/路由,getCurrentRequest
功能在这里可用。
class AppExtensions extends AbstractExtension
private $requestStack;
private $environment;
public function __construct(RequestStack $requestStack, Environment $environment)
$this->requestStack = $requestStack;
$this->environment = $environment;
public function getMainMenuWidget()
/** @var Request $request */
$request = $this->requestStack->getCurrentRequest();
$pathInfo = $request->getPathInfo();
// get current route
$route = $pathInfo['_route'];
$menu = [];
return $this->environment->render('widgets/MainMenu.html.twig', [
'menu' => $menu,
]);
