Newsletter option in contact us in magento

How can I add checkbox functionali开发者_如何转开发ty when it checked email of contact us form subscribe to the newsletter?

Edit the contact form and add in your own checkbox, and then modify the contacts controller using the method above (Mage_Contacts_IndexController)

You would then add in some code to subscribe to the newsletter using the email address from the posted form:

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