Add first/last name in newsletter module Magento

 >> First add two fields ( subscriber_firstname, subscriber_lastname) in newsletter_subscriber table and app\design\frontend\THEME\default\template\newsletter\subscribe.phtml.

    >> Now edit this page : app\code\core\Mage\Newsletter\controllers\SubscriberController.php

        Here you'll find "public function newAction()"
            Paste the below code after this following code:
            $status = Mage::getModel('newsletter/subscriber')->subscribe($email);    //line (63)

     ///////////////////////// First Name //////////////////////////////

            if ($this->getRequest()->getPost('subscriber_firstname'))
                {
                     $subscriber = Mage::getModel('newsletter/subscriber')->loadByEmail($email);
                     $name     = (string) $this->getRequest()->getPost('subscriber_firstname');
                     $subscriber->setSubscriberFirstname($name);
                     $subscriber->save();
                }

     //////////////////////  END  ///////////////////////////////////////

            Do same for field Last Name....

    >> The above code will effect your frontend. If you want to see the information from Admin too, you have to implement a little bit.

    Go to this link : app\code\core\Mage\Adminhtml\Block\Newsletter\Subscriber\grid.php
    Add this code :

    //It will show the information to the admin on News Letter Subscriber Section.
    $this->addColumn('subscriber_firstname', array(
            'header'    => Mage::helper('newsletter')->__('Subscriber First Name'),
            'index'     => 'subscriber_firstname',
            'default'   =>    '----'
        )); 

    *Note :- I would suggest to override the subscriber controller and admin blocks. In this post I've focused in the logic only and shown in 3 steps to understand you its very simple. But it's not good programming. You should follow the magento module structure. In my another post you'll see that how to override frontend and admin controllers.
