 * I’ve seen many people ask questions on either how to bulk import many invitation
   codes, or asking the developer of this plugin to create this as a feature. In
   case any of you need to do this I’m going to explain my method on accomplishing
   this task.
 * 1) Access you PHPmyadmin (you can user the plugin adminer to do this if you do
   not have direct access.
 * 2) The data for register redux invitation codes is stored with the wp_options
   as serialized information.
 * 3) Format your data as such ‘variable’, (you can do this with many methods, an
   option is excel.
 * 4) Create a PHP array using that information. You can use [http://www.w3resource.com/php/function-reference/serialize.php](http://www.w3resource.com/php/function-reference/serialize.php)
   to generate that array into serialized data.
 * 5) Copy the serialized data into the database mentioned in step 2.
 * 6) Now if you look in the Register Redux plugin within wordpress (where you typically
   insert invitation codes one by one) you’ll notice that all codes are now there.
 * I’ve done this with 11,000 codes.

 * you have to insert the serialized data into tbl “_options” @ field “register_plus_redux_invitation_code_bank-
   rv1”

 * _Concerning plugin version 4.0.3_
 * Be aware that more then 1000 Codes will produce a php warning:
    `PHP Warning:
   Unknown: Input variables exceeded 1000`
 * This ends up in losing the ability to save your options for this plugin via the
   backend.
    You can only save your options by modifying the tbl _options directly.
 * You could increase max_input_vars in your php.ini but I don’t recommend this 
   for productive systems.

 * Or using a Perl script to insert codes into the table, I’ve managed to get 55000
   invitation codes entered using this method, the only downside is accessing the
   dashboard if the invitation code widget is used, and accessing the register plus
   settings page, but if everything is set there shouldn’t be a reason to.
