I have created the custom module. but at the time of creating seller, I want an additional text box to add meta tag. meta description, meta keywords same like "add product" form in Magento admin panel.

Indexcontroller.php

 public function createPostAction() {

    $session = Mage::getSingleton('customer/session');

    if ($session->isLoggedIn()) {

        $this->_redirect('demoreq/seller/dashboard');

        return;

    }



    if ($this->getRequest()->isPost()) {

        $data = $this->getRequest()->getPost();



        /* save a customer */

        $customer = Mage::getModel("customer/customer");

        $confirmkey = $customer->getRandomConfirmationKey();



        $customer->setWebsiteId(Mage::app()->getWebsite()->getId())

                ->setStore(Mage::app()->getStore())

                ->setFirstname($data['firstname'])

                ->setLastname($data['lastname'])

                ->setEmail($data['email'])

                ->setPassword($data['password'])

                ->setGroupId(6)

                ->setConfirmation($confirmkey);



        try {

            $customer->save();

            $customer->sendNewAccountEmail(

                    'confirmation', Mage::getUrl('demoreq/seller/login'), Mage::app()->getStore()->getId()

            );



            /* save a seller */

            $seller = Mage::getModel('demoreq/seller');

            $data['customerid'] = $customer->getId();

            $lastid = Mage::getModel('demoreq/seller')->getCollection()->getLastItem()->getSellerid();

            ++$lastid;

            $vendorid = "GIS" . str_pad($lastid, 3, "0", STR_PAD_LEFT);

            $data['vendor_code'] = $vendorid;

            Mage::getModel('demoreq/seller')->setData($data)->save();

            $session->setData('sellerdata', '');

            Mage::getSingleton('core/session')->addSuccess($this->__('Account confirmation is required. Please, check your email for the confirmation link.'));



            //send confirm message

            $url = "http://167.114.117.218/rest/services/sendSMS/sendGroupSms?AUTH_KEY=edc6dda5c95eb6534d8878d711c6d6e4";

            $postData = array(

                'mobileNumbers' => $data['phone'],

                'smsContent' => "you are registered on posforyou.",

                'senderId' => "DEMOOS",

                'routeId' => 1,

                'smsContentType' => "english"

            );

            $data_json = json_encode($postData);



            // init the resource

            $ch = curl_init();



            curl_setopt_array($ch, array(

                CURLOPT_URL => $url,

                CURLOPT_HTTPHEADER => array('Content-Type: application/json', 'Content-Length: ' . strlen($data_json)),

                CURLOPT_RETURNTRANSFER => true,

                CURLOPT_POST => true,

                CURLOPT_POSTFIELDS => $data_json,

                CURLOPT_SSL_VERIFYHOST => 0,

                CURLOPT_SSL_VERIFYPEER => 0

            ));



            //get response

            $output = curl_exec($ch);



            //Print error if any

            if (curl_errno($ch)) {

                echo 'error:' . curl_error($ch);

            }

            curl_close($ch);



            $this->_redirect('demoreq/seller/login');

        } catch (Mage_Core_Exception $e) {

            $session->setData('sellerdata', $data);

            $message = $e->getMessage();

            Mage::getSingleton('core/session')->addError($message);

            $this->_redirect('demoreq/seller/create');

        }

        return;

    }

    }

You can add these (meta_title,meta_keyword,meta_description) fields in your module table.

Then add this code in your module form of adminhtml

$fieldset->addField("meta_title", "text", array(

        "label" => Mage::helper("demoreq")->__("Meta Title"),

        "name" => "meta_title",

        'required' => 'required',

));

$fieldset->addField("meta_keyword", "textarea", array(

        "label" => Mage::helper("demoreq")->__("Meta Keyword"),

        "name" => "meta_keyword",

        'required' => 'required',

));

$fieldset->addField("meta_description", "textarea", array(

        "label" => Mage::helper("demoreq")->__("Meta Description"),

        "name" => "meta_description",

        'required' => 'required',

));

[EDIT]
If you want set these vale on front-end then you can set it via your frontend controller.For this add this code.

$this->loadLayout();

/* get you title, description, and key here 

*

*/

$this->getLayout()->getBlock('head')->setTitle($title);

$this->getLayout()->getBlock('head')->setDescription($description);

$this->getLayout()->getBlock('head')->setKeywords($keyword);

$this->renderLayout();

And clear your magento cache storage.
