Bhavesh Patel on "Import users from non-wordpress database"

Hi iamdanieljs,

You can create your own script to handle this task. Its very simple task though.

You have to create custom database connection for fetching data from eventbooking_clients table
Create one array namely users to get users data from eventbooking_clients table.
Close this database connection after getting all the users in array.

//For Example

foreach($users as $user){
   $user_id = username_exists( $user['user_name'] );
   if ( !$user_id and email_exists($user['mail']) == false ) {
      $random_password = wp_generate_password( $length=12,
                         $include_standard_special_chars=false );
      $user_id = wp_create_user($user['user_name'], $random_password,  $user['email']);
  } else {
    $random_password = __('User already exists.  Password inherited.');
  }
}

If you want to do this task on regular basis(Example:execute a script on daily basis) than you can create one Cron job for it.
Also you can manage this by inserting one new column like last_updated date in eventbooking_clients table and fetch only required users.
