Hi, I would like to perform a validation on a profile field dispalyed in user registration. If this validation fail, I would like to create the user account and set his state to blocked. If success, then the user will remain as active. Please hlep me how can I achieve this functionality. Right now, I'm performing the validation implementing hook_user in profile module. But how do I make the user status as blocked instead of active, if the profile field validation fails?
