Is there a way for me to change the prefix based on which page the user register from? For example I have two landing page, if the user register from landing page A, the username will be FB(A) – User123.

Thanks.

Hi @alexius94,
You should track your user on those pages. For example, you can create a cookie with JavaScript, so you will know later which page was visited by the user.

Then, Nextend Social Login has a filter where you can modify the email and the username too.
```
        $userData = array(
            'email'    => $email,
            'username' => $sanitized_user_login
        );

        $userData = apply_filters('nsl_' . $this->getId() . '_register_user_data', $userData);
```
So your code would be for Facebook:
```
add_filter('nsl_facebook_register_user_data', function($userData){
    if(isset($_COOKIE['page']) && $_COOKIE['page'] == 'A'){
        // Note: username already contains the prefix here. So in this case, I replace fb_ with fba_
        // username already validated. Make sure you do modify it to a valid username or do the username validaton here again.
        $userData['username'] = preg_replace('/ˆfb_/', 'fba_', $userData['username']);
    }
    return $userData;
});
```
BTW:
I suggest you do not change the username based on the page. I think it would be better and simpler to set a user meta based on the source page. In that case, you should create the very same cookie as before. Then use the nsl_register_new_user action:
```
add_action('nsl_register_new_user', function($user_id){
    if(isset($_COOKIE['page']) && $_COOKIE['page'] == 'A'){
        update_user_meta( $user_id, 'page', 'A' );
    }
});
```
Then you can add another plugin which allows you to filter by users by meta, for example: https://wordpress.org/plugins/amr-users/

Ps.: I have not tested the codes, but if you follow the logic, you should be fine.

Hi, the cookie that I’ve set on the page doesn’t seems to be detected by the function. I think it’s because that after the user clicks on the button, the page will redirect away. Is there a way for me to pass the page as a parameter for the function instead?

Hi @alexius94,
if you set the cookie properly (expiration, path, etc…), you should be able to access its data in PHP.

I would like to help you find the cause, but I will need the link to both of your pages which sets the page cookie. Could you send them to support@nextendweb.com?

It turned out that the cookie was not set correctly (path and expiration). To set cookies with JavaScript use the following code:
```
function setCookie(name,value,days) {
  var expires = "";
  if (days) {
    var date = new Date();
    date.setTime(date.getTime() + (days*24*60*60*1000));
    expires = "; expires=" + date.toUTCString();
  }
  document.cookie = name + "=" + (value || "") + expires + "; path=/";
}
setCookie('page', 'FB-App', 7);
```
