You mean when user logs in he get’s different TAN?

Yes, why not. You would either store that TAN code in session or in database so you can track which code you’ve sent.

Hi Marijan,

Thanks for the helpful tutorial. I was wondering. Is it possible to generate TAN codes on the spot (after authentication with user/pass perhaps) and send the TAN code by mail/sms.

I’m trying to make use of a (secure) authentication method for my website, and i’m thinking of implementing TAN by SMS.

Regards,
Oguzhan U.

One way is to assign each user a group with some privileges and to each page privilege that is required to access it. A better example you can find in these two posts (Permissions Using Bitwise and Implementing Bitwise Permissions).
Using session_destroy() functions should work and log out user.

Really like this script, not seen an example like this before.

Once a user logged in how can you allow/prevent access to particular pages and how would you log them out, I’ve tried using the session but seen to be missing something.

You can easily do it with window.location. When you get AJAX response that user is authenticated you can do window.location = “http://where.you.want.to.redirect”.

I found your advanced user login module very useful. However i want to know if there is anyway we can implement redirect to another page after successful authentication. How best can this be done and what are the codes to use. Thanks for your reply

You should have array with two dimensions for errors so you do not have $return['msg'] but $return['msg'][]. Next you should remove break lines. Then you have to, in jQery part, where you have

if (data.error === true) {
    ...
}

a dd for loop that will echo each error.

What should I do to make the script show more than one error at a time? I guess I need to use some form of loop.

Ex: Show both “You did not enter your email.” and “You did not enter your password.” if non of them are filled in.

You can make same thing for normal page (save user to session and then check if he has privileges to access this part of the page) .
