Check if product has uploaded image In Magento 2

Question

I need to generate an email template with product image included in it, i need to check if the product image exist or not , if product image not exist i want to generate magento 2 default product image thumbnail with custom size, now i'm generating custom size product image with this:

$product = $objectManager->create('Magento\Catalog\Model\Product')->load($data['item_id']);
$imageHelper = $objectManager->get('\Magento\Catalog\Helper\Image');
$width = 150; $height = 150;
$imageUrl = $imageHelper->init($product,'product_page_image_small')->setImageFile($product->getFile())->resize($width,$height)->getUrl();
echo $imageUrl;

because the product doesn't have image it produce url like this:

Answer 1

Inject \Magento\Catalog\Api\ProductRepositoryInterfaceFactory in our constructor.

protected $_productRepositoryFactory;

public function __construct(
        \Magento\Catalog\Api\ProductRepositoryInterfaceFactory $productRepositoryFactory
) {

    $this->_productRepositoryFactory = $productRepositoryFactory;
}

We can get the image as follows

$product = $this->_productRepositoryFactory->create()->getById($item->getProductId());
$product->getData('image');
$product->getData('thumbnail');
$product->getData('small_image');

$product->getData('image') will return empty value if product has no base image. So you can use that condition and if product has no base image then you can print placeholder image url.
