How to implement data model with this code - zend-framework

Question

I am new to zend frame work . I am trying to learn zf create db-table tblename,zf create model tblname,zf create model tblnameMapper.
add user.php (form)
<?php
class Application_Form_Adduser extends Zend_Form
{
public function init()
{
$this->setMethod('post');
$username = $this->createElement('text','username');
$username->setLabel('Username:')
->setAttrib('size',10);
$password=$this->createElement('text','password');
$password->setLabel('Password')
->setAttrib('size',10);
$reg=$this->createElement('submit','submit');
$reg->setLabel('save');
$this->addElements(array(
$username,
$password,
$reg
));
return $this;
}
add user view:
<?php
echo 'Add user';
echo "<br />" .$this->a;
echo $this->form;
?>
admin controller:
<?php
class AdminController extends Zend_Controller_Action
{
public function adduserAction(){
$form = new Application_Form_Auth();
$this->view->form = $form;
$this->view->assign('a','Entere new user:');
if($this->getRequest()->isPost()){
$formData = $this->_request->getPost();
$uname=$formData['username'];
$pass=$formData['password'];
$msg=$uname." added to database successfully";
$this->view->assign('a',$msg);
$db= Zend_Db_Table_Abstract::getDefaultAdapter();
$query="INSERT INTO `user` ( `id` , `uname` , `password` )
VALUES ('', '{$uname}', '{$pass}');";
$db->query($query);
}}
i want to implement db-table with the above code .i am new to zend frame work i spend some time on reading programmers guide but in vain .It is very hard to get things from manual.So please some one explain step by step procedure for implementing the same .Thanks in advanced.

Ok here is a quick example:
Create DbTable Model (Basically an adapter for each table in your database):
at the command line: zf create db-table User user add -m moduleName if you want this in a module. This command will create a file name User.php at /application/models/DbTable that looks like:
class Application_Model_DbTable_User extends Zend_Db_Table_Abstract {
protected $_name = 'user'; //this is the database tablename (Optional, automatically created by Zend_Tool)
protected $_primary = 'id'; //this is the primary key of the table (Optional, but a good idea)
}
now to create a method in your DbTable model that executes the query from your controller, add a method similar to:
public function insertUser(array $data) {
$Idata = array(
'name' => $data['name'] ,
'password' => $data['passowrd']
);
$this->insert($Idata); //returns the primary key of the new row.
}
To use in your controller:
public function adduserAction(){
$form = new Application_Form_Auth(); //prepare form
try{
if($this->getRequest()->isPost()){//if is post
if ($form->isValid($this->getRequest()_>getPost()){ //if form is valid
$data = $form->getValues(); //get filtered and validated form values
$db= new Application_Model_DbTable_User(); //instantiate model
$db->insertUser($data); //save data, fix the data in the model not the controller
//do more stuff if required
}
}
$this->view->form = $form; //if not post view form
$this->view->assign('a','Entere new user:');
} catch(Zend_Exception $e) { //catach and handle exception
$this->_helper->flashMessenger->addMessage($e->getMessage());//send exception to flash messenger
$this->_redirect($this->getRequest()->getRequestUri()); //redirect to same page
}
}
This is about as simple as it gets. I have barely scratched the surface of what can be accomplished in simple applications with Zend_Db and a DbTable model. However you will likely find as I have, that at some point you will need more. That would be the time to explore the domain model and mappers.
For a really good basic tutrial that includes all of this and more please check out Rob Allen's ZF 1.x tutorial
I hope this helps.
