Magento 2: How to get custom attribute value in new template

Question

I need to get the value of a custom attribute on the product page, as I want to display different sizechart per attribute. For this reason, I have created the following .phtml to get the value of the attribute:

File: /app/design/frontend/Mgs/claue/Magento_Catalog/templates/product/view/sizechart.phtml

<?php 
$_product = $block->getProduct();
$attribute = $_product->getResource()->getAttribute('sizechart2');
?>

And I have called this file from:

File: /app/design/frontend/Mgs/claue/Magento_Catalog/layout/catalog_product_view.xml
<referenceContainer name="product.info.main">
            <block class="Magento\Framework\View\Element\Template" name="custom.text" template="Magento_Catalog::product/view/sizechart.phtml" after="product.info.price"/>
</referenceContainer>

But when I go to product page show the following error:

Fatal error: Uncaught Error: Call to a member function getResource() on null

What is the problem? :(

Thanksss

Answer 1

Your template is getting value from the Block class as you've mentioned in the xml.

Magento\Framework\View\Element\Template does not have any product instance.

In your xml you can simply modify your xml by the below

File: /app/design/frontend/Mgs/claue/Magento_Catalog/layout/catalog_product_view.xml
<referenceContainer name="product.info.main">
            <block class="Magento\Catalog\Block\Product\View" name="custom.text" template="Magento_Catalog::product/view/sizechart.phtml" after="product.info.price"/>
</referenceContainer>

Note: I have changed from Magento\Framework\View\Element\Template to Magento\Catalog\Block\Product\View

Create attribute1.phtml file and call all your attributes inside that file.

app/design/frontend/VENDOR/THEME/Magento_Catalog/templates/product/view/attribute1.phtml

Add your attribute code.

<?php echo $this->helper('Magento\Catalog\Helper\Output')->productAttribute($block->getProduct(), $block->getProduct()->getAttributeCode(), 'attribute_code'); ?>

Inside your xml file,

app/design/frontend/VENDOR/THEME/Magento_Catalog/layout/catalog_product_view.xml


<referenceBlock name="product.info.main">
    <block class="Magento\Catalog\Block\Product\View" name="attribute1" template="product/view/attribute1.phtml" />
</referenceBlock>

after that move your attribute1 block where ever you want.

for example,

<move element="attribute1" destination="product.info.main" before="product.info.price" />

Thanks....

try this it will help you.

<?php
$_helper = $this->helper('Magento\Catalog\Helper\Output');
$_product = $block->getProduct(); 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->get('Magento\Framework\Registry')->registry('current_product');//get current product
$productTypeInstance = $product->getTypeInstance();
if ($product->getTypeId() == \Magento\ConfigurableProduct\Model\Product\Type\Configurable::TYPE_CODE) 
{
    $usedProducts = $productTypeInstance->getUsedProducts($product);

    $data = explode(',',$_product->getData('your_attribute'));
    if(count($data) > 1)
    { 
        foreach($data as $key => $value):                    
            $attr = $_product->getResource()->getAttribute('your_attribute');
            if ($attr->usesSource()): 
                $option_value = $attr->getSource()->getOptionText($value);
                echo $option_value;
            endif;
        endforeach;
    }
}
