Description

The wpforms_form_locker_age_get_error_message filter lets you customize the age verification error message displayed by the Form Locker addon when a user does not meet the minimum age requirement. By default, WPForms shows a standard message, but you can override it with your own wording.

This filter is especially useful when you want to add context-specific language to your forms. For example, you can use it to explain why a user is restricted or suggest alternative actions if they fail age verification.
