我正在尝试通过我的插件创建一个文档，该文档在里面MyPlugin/Resources/views/documents/index_foo.tpl，我已经通过订阅事件注册了模板Enlight_Controller_Action_PostDispatchSecure

还添加了模板目录$this->template->addTemplateDir($this->pluginDir . '/Resources/views/'); 及其在表中的条目，s_core_documents 但是当我尝试通过去预览它时Basic Settings > PDF Document Creation > Preview

我得到这个错误

但是，当我将模板放入其中时themes/Bare/documents，它可以工作。

知道如何使用我自己的插件来实现这一点吗？

在 Shopware 社区中询问后，Shyim 说订阅的事件来不及了，而是使用这里提到的事件

https://developers.shopware.com/developers-guide/event-list/#theme_inheritance_template_directories_collected

使用事件后，我们Subscriber/TemplateRegistration.php看起来像这样

class TemplateRegistration implements SubscriberInterface
{
    /**
     * @var Enlight_Template_Manager
     */
    private $template;
    private $pluginDir;
    /**
     * TemplateRegistration constructor.
     * @param Enlight_Template_Manager $template
     * @param $pluginDir
     */
    public function __construct(Enlight_Template_Manager $template, $pluginDir)
    {
        $this->template = $template;
        $this->pluginDir = $pluginDir;
    }
    /**
     * @inheritDoc
     */
    public static function getSubscribedEvents()
    {
        return [
            'Theme_Inheritance_Template_Directories_Collected' => 'onCollectTemplateDirectories',
        ];
    }
    /**
     * @param \Enlight_Event_EventArgs $args
     */
    public function onCollectTemplateDirectories(\Enlight_Event_EventArgs $args)
    {
        $this->template->addTemplateDir($this->pluginDir . '/Resources/views/');
    }
}

但即使这样做我仍然面临错误说明

Ups! Ein Fehler ist aufgetreten!

在我调整了onCollectTemplateDirectories()我的方法中的事件返回后，上面的错误得到了解决Subscriber/TemplateRegistration.php

现在调整后是这个样子

class TemplateRegistration implements SubscriberInterface
{
    /**
     * @var Enlight_Template_Manager
     */
    private $template;
    private $pluginDir;

    /**
     * TemplateRegistration constructor.
     * @param Enlight_Template_Manager $template
     * @param $pluginDir
     */
    public function __construct(Enlight_Template_Manager $template, $pluginDir)
    {
        $this->template = $template;
        $this->pluginDir = $pluginDir;
    }

    /**
     * @inheritDoc
     */
    public static function getSubscribedEvents()
    {
        return [
            'Theme_Inheritance_Template_Directories_Collected' => 'onCollectTemplateDirectories',
        ];
    }

    /**
     * @param \Enlight_Event_EventArgs $args
     */
    public function onCollectTemplateDirectories(\Enlight_Event_EventArgs $args)
    {
        // commented the line below
        // $this->template->addTemplateDir($this->pluginDir . '/Resources/views/');

        // and used this one instead
        $dirs = $args->getReturn();
        $dirs[] = $this->pluginDir . '/Resources/views';
        $args->setReturn($dirs);
    }
}

Telgi 在社区中解释了这背后的技术原因，

您必须根据您订阅的事件使用其中一个或另一个。您需要调整事件的返回。如果您订阅另一个事件，则需要模板服务

现在终于，当我按下模板的预览按钮时，Basic Settings > PDF Document Creation > Preview我看到了模板中写的内容/文本，并且没有更多错误。

希望这对将来的某人有所帮助。
