How to authenticate against CSV file

So is there a better way to do it…

Since you asked… why don’t you just loop through your csv file ( either line by line or read it into an array ), add the users, and be done with it?

Drop this in you theme’s functions.php and try to log in.

function test_wp_auth() {
  print_r(get_defined_vars());
  exit; // sometime needed; sometimes not
}
add_action('wp_authenticate','test_wp_auth');

Now you know what variables you have available.

However, I’d still not do it the way are doing it. It just seems like more work to me to interrupt the login process to add users dynamically. …could just be a personality glitch 🙂 I’d add all the users in one shot a simple ‘last_login’ tracker like this:

function my_user_last_login($login) {
    global $user_ID;
    $user = get_userdatabylogin($login);
    update_usermeta( $user->ID, 'my_user_last_login', time() );
}
add_action('wp_login','my_user_last_login');

Then after six months or so remove any users who haven’t logged in.
