Error: "Name Prefix" is a required value in Magento 2.2

Question

I have made required 'Show Prefix' from admin config setting. Now prefix is shown on the customer account edit page.

But, when i am trying to save customer prefix, then i am getting Error: "Name Prefix" is a required value."

---

I have also used 'Prefix Dropdown Options' but again, I am getting same error.

I am getting this error in Magento Ver 2.2.1, Ver 2.2.2 and Ver 2.2.3. Is anybody else getting this type error?

Answer 2

This is not a error, its just validating the form data, if you dont want prefix as a required field, then you can change to OPTIONAL from the magento admin customer configuration settings.

Steps: MagentoAdmin->Stores->Configuration->Customer->CustomerConfiguration->Name and Address Options->Show Prefix->Optional

Answer 3

In my case, the reason was a missed value in the table customer_form_attribute.

Check if all form codes are maped to prefix attribute:

adminhtml_checkout
adminhtml_customer
customer_account_create
customer_account_edit

Probably missed adminhtml_customer form code is a cause of the issue.

Answer 4

You just need this:

Go to: Configuration -> Customers tab -> Customer Configuration -> Name and Address Options section -> Show Prefix -> No

Clean the cache, and you will get removal of Name Prefix option from frontend.
