The newsletter subscription module in Magento has only one field (email) by default. After I add an extra field to the form (say country), how can I get the form data to show up in the Magento back-end and be sent as an email to a preset recipient? Thanks.

There are a few things that you need to take care of to make this work:

  1. Add a new column for your data to the appropriate database table
  2. Make sure that magento saves your new field to the database
  3. Present the data in the admin backend
  4. Record the data when you get a new newsletter subscription

Here's how you can do all those things:

Ad. 1)

Using phpMyAdmin, mySQL command line, or whatever is your preferred DB manipulation method, add a new column "country" as, say, varchar(100) to the newsletter_subscriber table.

Ad. 2)

Magento will automaticly give you access to the new field through the getCountry() and setCountry() methods on the Mage_Newsletter_Model_Subscriber object. The only thing it won't do is save your field back to the DB after it has been changed with code somewhere in the system. To get it saved you need to modify _prepareSave(Mage_Newsletter_Model_Subscriber $subscriber) function found in Mage_Newsletter_Model_Mysql4_Subscriber (app/code/core/Mage/Newsletter/Model/Mysql4/Subscriber.php). Be sure to make a local copy of the file first and not modify the core file. Here's what you need to add:

protected function _prepareSave(Mage_Newsletter_Model_Subscriber $subscriber)
{
    $data = array();
    $data['customer_id'] = $subscriber->getCustomerId();
    $data['store_id'] = $subscriber->getStoreId()?$subscriber->getStoreId():0;
    $data['subscriber_status'] = $subscriber->getStatus();
    $data['subscriber_email']  = $subscriber->getEmail();
    $data['subscriber_confirm_code'] = $subscriber->getCode();

    //ADD A NEW FIELD START

    //note that the string index for the $data array
    //must match the name of the column created in step 1
    $data['country'] = $subscriber->getCountry();

    //ADD A NEW FIELD END
    (...)
}

Ad. 3)

You will need to modify (a local copy of) the file app/code/core/Mage/Adminhtml/Block/Newsletter/Subscriber/Grid.php. The method you are looking for is called _prepareColumns(). In there you will see a series of calls to $this->addColumn(). You need to add a corresponding call for your "Country" field with the following code:

$this->addColumn('country', array(
    'header'    => Mage::helper('newsletter')->__('Country'),
    //the index must match the name of the column created in step 1
    'index'     => 'country',
    'default'   =>    '----'
));

If you want the field to appear at the end of the grid (as the last column) add it as the last call, otherwise squeeze it between the existing calls exactly where you want it to end up in the admin.

Ad. 4)

This is a part I did not have to do in my customisation of the magento newsletter, so it will be mostly theoretical. The subscription occurs in the controller located at app/code/core/Mage/Newsletter/controllers/SubscriberController.php. Here's the code of the newAction method with my proposed changes:

public function newAction()
{
    if ($this->getRequest()->isPost() && $this->getRequest()->getPost('email')) {
        $session   = Mage::getSingleton('core/session');
        $email     = (string) $this->getRequest()->getPost('email');

        try {
            if (!Zend_Validate::is($email, 'EmailAddress')) {
                Mage::throwException($this->__('Please enter a valid email address'));
            }

            $status = Mage::getModel('newsletter/subscriber')->subscribe($email);
            if ($status == Mage_Newsletter_Model_Subscriber::STATUS_NOT_ACTIVE) {
                $session->addSuccess($this->__('Confirmation request has been sent'));
            }
            else {
                $session->addSuccess($this->__('Thank you for your subscription'));
            }

                //ADD COUNTRY INFO START

                //at this point we may safly assume that subscription record was created
                //let's retrieve this record and add the additional data to it
                $subscriber = Mage::getModel('newsletter/subscriber')->loadByEmail($email);

                //assuming that the input's id is "country"
                $subscriber->setCountry((string) $this->getRequest()->getPost('country'));

                //don't forget to save the subscriber!
                $subscriber->save();

                //ADD COUNTRY INFO END
        }
        catch (Mage_Core_Exception $e) {
            $session->addException($e, $this->__('There was a problem with the subscription: %s', $e->getMessage()));
        }
        catch (Exception $e) {
            $session->addException($e, $this->__('There was a problem with the subscription'));
        }
    }
    $this->_redirectReferer();
}

Going through the above steps should take care of the most part of your problem. Let me know how that last part worked out, as I did not have a chance to test it.

Once you have your additional field in the Subscriber object you can do whatever you want with it. I did not really get what you mean by

be sent as an email to a preset recipient

If you can explain that I will try to help you out with this part too.

Edit - how to send a mail when someone subscribes

Just add the following code to the controller after the part which adds country to a subscriber object.

$mail = new Zend_Mail();
$mail->setBodyHtml("New subscriber: $email <br /><br />Country: ".$this->getRequest()->getPost('country'));
$mail->setFrom("[email protected]")
->addTo("[email protected]")
->setSubject("Your Subject here");
$mail->send();

thanks for a brilliant reply. 'be sent as an email.." means i'd like the subscriber info (email and country in this case) to be sent as an email to the admin (say [email protected]). so i have the info added to the database and sent as an email too. thanks
