Adding custom product attribute properties in Magento 2

Question

How to add custom product attribute properties in admin for admin?

• Magento2 has removed attribute filter to product type.

• So,in frontend layer-navigation I'm getting attribute filter of it's child product also for bundle and configurable product in category page.

• I want to add 'Apply To' property when i create new attribute.

• When I'm creating attribute I want to set scope for product type as we were did in magento1.

Anyone know how can I do this?I found something which may help.

Answer 1

You used attribute code like below. Into code we need to add field

'apply_to'

and into that you need to specify types of product for which you used above attribute. Here I create attribute only for Simple, Group and Bundel type of product.

$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'myattribute',
            [
                'type' => 'text',
                'label' => 'My Atrribute',
                'input' => 'text',
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                'visible' => true,
                'apply_to' => 'simple,grouped,bundle'
            ]
        );

In Magento 2, there is no option to choose a specific product while creating product attribute.

Easy for your reference: What happened to the "Apply to" feature on product attributes in Magento 2?

You can achieve this in two ways.

By creating attribute via setup script:

If you want to create a custom attribute for a specific product type, we can use the setup script apply_to parameter.

Easy for your reference: Magento2 custom attribute for specific product type

By direct mysql qurey:

If you want to change the admin created custom attribute, we can directly change the apply_to in the database by using the below query.

Note: apply_to default value is NULL.

update catalog_eav_attribute set apply_to="simple" where attribute_id = (select attribute_id from eav_attribute where attribute_code="test");

Hope it helps.
