Magento 2 implements the “service contracts” design pattern, which comprises a set of PHP interfaces defined for a module. A service contract encompasses both service and data interfaces. These interfaces conceal the intricacies of business logic from service requestors like controllers, web services, and other modules.

Magento developers frequently encounter problems accessing custom attributes during product collection loading. For example, when you try to get a product from a quote or a wishlist item. As a result, we’ve identified intriguing workarounds to circumvent this issue, such as repeatedly loading the product. However, there is a proper way to make these attributes accessible. We would like to tell you more about it.

In this post, we aim to share our expertise on creating a category attribute in Magento 2. As you may have noticed, we need to change (add or customize) category attributes from time to time. We have done it many times for Magento 1 and now we faced the same task in Magento 2. This process is very similar for both Magento versions, however there are some differences. So let’s check how we can do it step by step.

Upon creating an extension for Magento, quite often you face with a necessity to create a custom attribute for product, category, customer etc. Of course, you can add a description somewhere in the extension’s documentation how to do it and do not bother you head. However, all Magento versions allow you to create an attribute on the fly during an extension’s installation. There were many topics how to do that in Magento 1.x, and let’s check what is the difference in the next major version of Magento.

So you have added a new custom product attribute. It is not a problem to access and use it in Product View. And you probably know that you should enable it under the attribute settings page of Magento backend in order to make it available for the Product List (or category view) section. But what about checkout/cart area?

Getting all options of a specific attribute in Magento is fairly easy:

$attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'color');  
foreach ($attribute->getSource()->getAllOptions(true) as $option) {
    echo $option['value'] . ' ' . $option['label'] . "\n";
}
