Magento – Get product attribute value in new_grid.phtml magento

magentomagento2

I have problem with getting attribute value in new_grid.phtml. If i make it like this:

<?php $_product = $block->getProduct()
echo $_product->getData('attr_name') ?>

Page generating to this place, and after just blank page.

Please show me other option, or maybe i have mistakes in my code.

Here is the place in new_grid.phtml:

<div class="product-img-block">
<a href="<?php /* @escapeNotVerified */ echo $block->getProductUrl($_item) ?>" class="product-item-photo">
<?php echo $block->getImage($_item, $image)->toHtml(); ?>

/* my code: */
<?php $_product = $block->getProduct() ?>
<img src="<?php echo $_product->getData('attr_name') ?>" />
</a>

it is code from custom_home.xml

<container name="header.container" as="header_container" label="Page Header Container"  htmlTag="header" htmlClass="page-header" before="main.content"/>
<block class="Magento\Framework\View\Element\Template" name="test_file" template="Magento_Theme::html/front-slider.phtml" before="main.content"/>

<container name="main.content" htmlTag="main" htmlId="maincontent" htmlClass="page-main">
<container name="columns.top" label="Before Main Columns"/>

<container name="columns" htmlTag="div" htmlClass="columns">
                <container name="main" label="Main Content Container" htmlTag="div" htmlClass="column main"/>
            </container>
</container>

In front-slider.phtml i get the new_grid.phtml by code:

<?php echo $this->getLayout()->createBlock("Magento\Catalog\Block\Product\Widget\NewWidget")->setDisplayType("all_products")->setProductsCount("6")->setTemplate("product/widget/new/content/new_grid.phtml")->toHtml(); ?>

On this code:

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        
$appState = $objectManager->get('\Magento\Framework\App\State');
$appState->setAreaCode('frontend');
$registry = $objectManager->get('\Magento\Framework\Registry');
$_product= $registry->registry('current_product');
$attribute_code = 'attr_name';
echo  $_product->getResource()->getAttribute($attribute_code)-
>getFrontend()->getValue($_product);

Try adaptive this code to yours

    @var $block \Magento\Catalog\Block\Product\Widget\NewWidget 
    if ($exist = ($block->getProductCollection() 
    && $block->getProductCollection()->getSize())) 
    {
        $items = $block->getProductCollection()->getItems();
    }
    <?php foreach ($items as $_item): ?>
        <img src="<?php echo $_item->getData("nameofattribute") ?>" />
    <?php endforeach ?>

If you dont know name of attribute you may use $_item->getData() and get all of list data for current item.
