Using first and last names in Sitleok
For historical reasons, Sitleok uses a single field to store a user's full name rather than separate fields for first and last name. Sitelok can still display the users first or last name separately on pages or in emails though using built-in variables.
To ensure that users do enter their full name instead of just a first or last name in registration and update profile forms you can use form validation. In the form designer just select the name field and set the Validation as Word Limit within a minimum of 2 like this.
W3 recommends using a single name field rather than first and last name fields as this isn't appropriate in all countries and cultures https://www.w3.org/International/questions/qa-personal-names
Often sites use the first name as a friendly greeting such as 'Dear Michael'. In North America and many European countries this is fine but it's not always appropriate. Instead, you could consider using a custom field to store the users own choice. For example, you could have a custom field labeled 'What should we call you'.
If you do require the first and last names to be actually stored separately (not often required in reality) then you can use the name field to store one name and a custom field to store another.
