I'm looking for a way to make some requirements on the customer registration form on Prestashop 1.5.6.2, so that the password should be at least six characters long and contain at least one capital letter.
The first thing with at least six characters is done, but need to configure the requirement of at least one capital letter in the password. Does anyone know how to do so?
Older customers should still be able to login with their old password.
Thanks.
