使用子视图渲染视图?

Render a view with a child view?

我正在尝试发送带有特定模板(电子邮件的主视图,例如 2 栏布局等)的特定 "layout"(针对 header/footer)的电子邮件。

$mainView html 有:<?= $this->content ?> 但是当它应该是 $childView html 和所有变量时它总是 NULL。

这是我在 MailService.php 文件中的内容:

public function createMessage($to, $subject, $template, $variables) : Message
{
    // Create mail
    $message = new Message();

    // Create mail body
    $mainView   = new ViewModel();
    $mainView->setTerminal(true);
    $mainView->setTemplate('layout/mail.phtml');

    $childView  = new ViewModel();
    $childView->setTerminal(true);
    $childView->setTemplate($template);
    $childView->setVariables($variables);

    $mainView->addChild($childView, 'content');

    $msgRender  = $this->viewRenderer->render($mainView);

    $body = new Part($msgRender);
    $body->setType(Mime::TYPE_HTML);

    $messageBody = new MessageBody();
    $messageBody->addPart($body);
    $message->setBody($messageBody);

    $message->setTo($to);
    $message->setSubject($subject);

    return $message;
}

$this->viewRenderer 注入工厂:

/** @var RendererInterface $viewRenderer */
$viewRenderer = $serviceLocator->get('viewrenderer');

好的,我成功了! :) 我必须渲染 childView 然后将此渲染设置为 mainView

的视图变量
public function createMessage($to, $subject, $template, $variables) : Message
{
    // Create mail
    $message = new Message();

    // Create mail body
    $mainView   = new ViewModel();
    $mainView->setTerminal(true);
    $mainView->setTemplate('layout/mail.phtml');

    $childView  = new ViewModel();
    $childView->setTemplate($template);
    $childView->setVariables($variables);
    $childRender = $this->viewRenderer->render($childView); // render child

    $mainView->setVariable('content', $childRender); // set childRender to mainView

    $msgRender  = $this->viewRenderer->render($mainView);

    $body = new Part($msgRender);
    $body->setType(Mime::TYPE_HTML);

    $messageBody = new MessageBody();
    $messageBody->addPart($body);
    $message->setBody($messageBody);

    $message->setTo($to);
    $message->setSubject($subject);

    return $message;
}
