I create a membership website on website that required registration to see full website. I also want users register from specific country. To archive this goal, I also add SMS verification on my registration page and restrict phone number field only for country that I want i.e.
923. If Phone number is not start with
923 phone field's boarder goes red and an alert box apear. But this is only alert and "mental hit", registation form still can be submit. Vague people can use create fake account by using fake number (like recive sms online) Now I want that if phone field not start with
Register button blocked and become unclickable other wise stay normal. How It possible?
Sorry for poor English. I hope you under stand what I want to do.Here is my Registration page. You can see phone number check script in footer. Thanks
