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.
