PHP 中的路由条件

Question

如果国家/地区是美国，setViewFileName 将使用 Which_Online_Shopper_Are_You_US/default。html.twig

，我该如何设定条件

public function routeWhich_Online_Shopper_Are_You(Get $request, Twig $response): array
{
    global $CONFIG;

    if (I18l::getCountryByDomain() !== "GB") {
        $response->redirect('/');
    }

    $siteName = $CONFIG['site_name'];
    $siteUrl  = $CONFIG['site_url'];

    $context = [
        'siteName' => $siteName,
        'siteUrl'  => $siteUrl
    ];

    $page = $this->project->config->getPage();
    $response->setViewFilename('Which_Online_Shopper_Are_You/default.html.twig');
    $page->setPageTitle('Which Online Shopper Are You');
    $page->updateMeta();

    return $context;
}

Answer 1

您可以将视图设置为可以根据当前国家覆盖的变量。

我还确保美国没有被重定向。

更多细节在下面的代码中添加为注释：

public function routeWhich_Online_Shopper_Are_You(Get $request, Twig $response): array
{
    global $CONFIG;

    // Add all the allowed countries
    $allowed = ['GB', 'US'];

    // Get the current country
    $currentCountry = I18l::getCountryByDomain();

    // Check if the current country is in the allowed array. If not, redirect
    if (in_array($currentCountry, $allowed) === false) {
        $response->redirect('/');
    }

    // Set the default view
    $viewFile = 'Which_Online_Shopper_Are_You/default.html.twig';

    // Now override the view if the country is US
    if ($currentCountry === 'US') {
        $viewFile = 'Which_Online_Shopper_Are_You_US/default.html.twig';
    }

    $siteName = $CONFIG['site_name'];
    $siteUrl  = $CONFIG['site_url'];

    $context = [
        'siteName' => $siteName,
        'siteUrl'  => $siteUrl
    ];

    $page = $this->project->config->getPage();

    // Let's use our dynamic viewFile variable to set the view
    $response->setViewFilename($viewFile);
    
    $page->setPageTitle('Which Online Shopper Are You');
    $page->updateMeta();

    return $context;
}
