Slim Framework 3 - 在全局模板中使用路由器

时间：2016-10-10 20:43:59

标签： php slim

我对Slim Framework 3比较陌生。我想了解的一件事是如何在“全局”模板中使用路由器$this->router。

我的意思是这是一个模板，例如导航菜单 - 每个页面上都会显示一些内容。

对于模板我按照我安装的example tutorial使用“php-view”库：

composer require slim/php-view

在我的模板目录中，我有一个名为nav.php的文件，我想输出我的链接。

我理解如何像这样调用路由器

<a href="<?=$router->pathFor('sign-up')?>">Sign Up</a>

但是......示例教程仅显示了如何从1个单独的地方传递该链接，例如$app->get('/sign-up' ... })->setName("sign-up");

如何在任何模板中全局使用路由器，而不将其作为参数传递到每个单独的URL路由中？

我更熟悉像CakePHP这样的框架，其中有一个“AppController”，它允许你设置全局，即在每个请求中都可用。我不知道这是否是在Slim中完成的，但这就是我所追求的效果。

好吧，您可以将其作为template variable传递。

当您在容器中实例化或注册PhpRenderer时，您有多个选项来定义＆＃34; global＆＃34;变量，即可在所有模板中访问的变量：

// via the constructor
$templateVariables = [
    "router" => "Title"
];
$phpView = new PhpRenderer("./path/to/templates", $templateVariables);

// or setter
$phpView->setAttributes($templateVariables);

// or individually
$phpView->addAttribute($key, $value);

假设您通过Pimple注册PhpRenderer：

<?php
// Create application instance
$app = new \Slim\App();

// Get container
$container = $app->getContainer();

// Register PhpRenderer in the container
$container['view'] = function ($container) {

    // Declaring "global" variables
    $templateVariables = [
        'router' => $container->get('router')
    ];

    // And passing the array as second argument to the contructor
    return new \Slim\Views\PhpRenderer('path/to/templates/with/trailing/slash/', $templateVariables);
};

您应该创建一个新类，例如MainMenu，你应该创建一个包含菜单所有路径的数组。 MainMenu的对象应返回带有标签和路径的数组，然后您可以将该数组传递给视图：

$menu = (new MainMenu())->buildMenu();
$response = $this->view->render($response, "index.phtml", [
    'menu' => $menu
]);

然后在您的*.phtml文件中，您可以访问$menu变量。但是，如果您不想在每条路线中重复该代码，该怎么办？

使用middlewares。您可以使用

从中间件传递变量 
$request = $request->withAttribute('foo', 'bar');

并检索

$foo = $request->getAttribute('foo');
