We had the post for pre-release Magento 2 – “How to make customer attribute?“. After this time Magento has several updates and we did update of files according to the latest Magento 2.1.3 release. The more detailed information can be found in the previous article.
Since Magento 2 is pretty close to release we can review how the adding of custom attribute process has been changed. Today we will make Magento 2 extension which adds customer attribute into customer edit page at admin.
To start with it we will have to have Magento 2 installed with Demo data. You can find Magento 2 Installation Guide at Magento 2 Developer Documentation.
