如何在Shopware自定义插件中获取「Shop settings > Mailers > Mail host」的值？

Absolutely! You can easily pull the SMTP host value from the Shop settings > Mailers > Mail host field in your custom Shopware plugin. The approach varies slightly depending on whether you're using Shopware 6 (the current stable version) or Shopware 5. Here's a breakdown:

Shopware 6 Implementation #

Shopware 6 uses the SystemConfigService to manage all system settings, including mailer configurations. Here's how to use it:

Step 1: Inject the SystemConfigService #

First, inject the SystemConfigService into your plugin's service, controller, or subscriber. For example, in a custom service:

use Shopware\Core\System\SystemConfig\SystemConfigService;

class MyCustomPluginService
{
    private SystemConfigService $systemConfigService;

    public function __construct(SystemConfigService $systemConfigService)
    {
        $this->systemConfigService = $systemConfigService;
    }

    // Your custom logic here
}

Make sure to register this service in your plugin's services.xml (or services.yaml) if you're using a custom service class.

Step 2: Fetch the SMTP Host Value #

Use the get() method to retrieve the configuration. The key for the default mailer's host is core.mailer.transport.default.host:

// Get the global SMTP host (applies to all sales channels unless overridden)
$smtpHost = $this->systemConfigService->get('core.mailer.transport.default.host');

// If you need the value for a specific sales channel, pass its ID as the second parameter
$specificSalesChannelId = 'your-sales-channel-uuid-here';
$smtpHostForChannel = $this->systemConfigService->get('core.mailer.transport.default.host', $specificSalesChannelId);

• If you've created a custom mailer (not the default one), replace default in the config key with your mailer's name (e.g., core.mailer.transport.my_custom_mailer.host).

Shopware 5 Implementation #

For older Shopware 5 installations, you can access the config directly via the Shopware container:

// Fetch the global mail config
$shopConfig = Shopware()->Container()->get('shopware.config');
$smtpHost = $shopConfig['mail']['host'];

// Or for a specific shop (in multi-shop setups)
$shopId = 1; // Replace with your shop ID
$shopConfig = Shopware()->Models()->getRepository(\Shopware\Models\Config\Config::class)->getShopConfig($shopId);
$smtpHost = $shopConfig['mail']['host'];

Notes #

• Ensure your plugin has the necessary permissions to access system configuration (this is enabled by default for most plugins).
• If the mailer configuration is overridden at the sales channel level, always pass the sales channel ID to get the correct value for that channel.
