Hi,

i wish to know how i going to implement to my website for the following situation:

for example, i have a website that allow all the user to view all the content without any login or register function.

Now i wish to add in the function that only allow the user which already register as a member to view the website contents.

To register as a member, the user need to click register and then key in their personal details like what other webpage do and then it need to be verify by using mobile phone. It means that, it will automatically send the verification code to the user mobile phone and then the user need to key in the verification code that he/she receive to become a member.

How should i going to implement this function??

thanks
