I created my product set, group and attributes inside.
$entityTypeId = $eavSetup->getEntityTypeId(Product::ENTITY);
$eavSetup->addAttribute(
$entityTypeId,
'si_qty',
[
'type' => 'int',
'backend' => '',
'frontend' => '',
'label' => 'Si Qty',
'input' => 'text',
'class' => '',
'source' => '',
'global' => 0,
'visible' => true,
'required' => false,
'user_defined' => true,
'default' => null,
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'used_in_product_listing' => false,
'unique' => false,
'apply_to' => 'mySpecialProductType',
'system' => 1,
'group' => 'My Group Name',
'option' => ['values' => []]
]
);
Currently I try to get the attribute value from catalog products page and product page.
// \Magento\Catalog\Model\Product $product
var_dump($product->getData('si_qty')); // => NULL
var_dump($product->getResource()->getAttribute('si_qty')->getFrontend()->getValue($product)); // => NULL
var_dump($product->getCustomAttribute('si_qty')); // => NULL
var_dump($product->getCustomAttributes()); // => ...
