Magento – Magento 2: I can’t display the value of a custom product attribute in product page

I can see two issues with your code:

1. Even though you may have named the attribute in lower case, you will still need to refer to it in your get method using CamelCase, for example:

   $eancode = Mage::getModel('catalog/product')->load($item->getProduct()->getId())->geteancode();
   

2. In the first line of protected function geteancode($item) function, you retrieve the ean value, and then you return the geteancode() function again on the following line which would return an empty String.

Your method should read:

  protected function geteancode($item)
 {
     return Mage::getModel('catalog/product')->load($item->getProduct()->getId())->getEancode();
 }

In Magento 2, the price is placed on the product view page via a XML file named catalog_product_view.xml

You can view it in the catalog module's layout folder:

app/code/Magento/Catalog/view/frontend/layout/catalog_product_view.xml

Or if you installed Magento 2 with Composer:

vendor/magento/module-catalog/view/frontend/layout/catalog_product_view.xml

A container named product.info.price is created on the product view page. In the container, a block named product.price.final is created.

You can move the block with the <move> method in XML (Move Instructions):

<move element="product.price.final" destination="content" before="-" />

You can also create another block that uses the same class & arguments:

<block class="Magento\Catalog\Pricing\Render" name="product.price.final.copy" after="product.info.sku">
    <arguments>
        <argument name="price_render" xsi:type="string">product.price.render.default</argument>
        <argument name="price_type_code" xsi:type="string">final_price</argument>
        <argument name="zone" xsi:type="string">item_view</argument>
    </arguments>
</block>

*The above snippet is derived from what is in the catalog_product_view.xml file.

I hope this points you in the right direction!
