loadByCode Newsletter template in Magento 2?

Question

Is there a Magento 2 function like loadByCode for admin created Newsletter templates?

If not, how are you supposed to retrieve newsletter created in admin?

Answer 1

This method is not available. So try following way:

Inject using DI:

public function __construct(
    \Magento\Newsletter\Model\TemplateFactory $newsletterFactory
) {
    $this->newsletterFactory = $newsletterFactory;
}

Now use following way:

$template_code = 'abc';
$newsletter = $this->newsletterFactory->create()->load($template_code, 'template_code');
print_r($newsletter->getData());

Another Way

Inject using DI:

public function __construct(
    \Magento\Newsletter\Model\ResourceModel\Template\CollectionFactory $newsletterCollectionFactory
) {
    $this->newsletterCollectionFactory = $newsletterCollectionFactory;

}

Now use following way:

$template_code = 'abc';
$newsletterCollection = $this->newsletterCollectionFactory->create()->addFieldToFilter('template_code', $template_code);
foreach ($newsletterCollection as $newsletter) {
    print_r($newsletter->getData());
}

[Update]

how do you actually send the newsletter template after loading it?

$template_code = 'abc';
$newsletter = $this->newsletterFactory->create()->load($template_code, 'template_code');

$this->transportBuilder->setTemplateData(
    [
        'template_subject' => $newsletter->getTemplateSubject(),
        'template_text' => $this->getTemplateText(),
        'template_styles' => $this->getTemplateStyles(),
        'template_filter' => $this->templateFilter,
        'template_type' => 2, // 2 for html
    ]
);

/* Magento\Newsletter\Model\ResourceModel\Subscriber\CollectionFactory*/
$collection = $this->subscriberCollectionFactory->create()->useOnlyUnsent()->showCustomerInfo()->setPageSize(
    20
)->setCurPage(
    1
)->load();

/** @var \Magento\Newsletter\Model\Subscriber $item */
foreach ($collection->getItems() as $item) {
    $transport = $this->transportBuilder->setTemplateOptions(
        ['area' => \Magento\Framework\App\Area::AREA_FRONTEND, 'store' => $item->getStoreId()]
    )->setTemplateVars(
        ['subscriber' => $item]
    )->setFrom(
        ['name' => 'sent from name', 'email' => '[email protected]']
    )->addTo(
        $item->getSubscriberEmail(),
        $item->getSubscriberFullName()
    )->getTransport();

    try {
        $transport->sendMessage();
    } catch (\Magento\Framework\Exception\MailException $e) {

    }
}
