Zend controller reuse

[gethinw]

Hi all,

 

I'm just starting out with Zend and am trying to get my head round a few concepts.

 

Basically, I have a site with a number of different pages (realised as controllers), each of which pulls data from a different database table and displays it. So, the site structure is something like this:

 

public/

  /news

  /biography

  /links

 

 

However, a few of these pages do the same thing to the data of their respective tables, and I was wondering how I'd go about reducing the amount of duplicated code. Something along the lines of:

 

class BasicController extends Zend_Controller_Action
{
//reusable code in here, using a variable $name
}

---------
class BiographyController extends BasicController
{
//passes 'biography' to $name variable
}

----------
class LinksController extends BasicController
{
//passes 'links' to $name variable
}

 

So, that's the idea, is that a sensible way of going about this? And how would I go about actually passing the variable?

 

Hope that that's clear - let me know if it's not, or if any more information would be useful!

 

Thanks,

Gethin

Never did this, but something like this should help:

 

class BasicController extends Zend_Controller_Action
{
    public static $variable = '';

    public function init()
    {
        self::$variable = 'assign value';
    }
}

class BioController extends BasicController
{
    public function indexAction()
    {
        $bioVar = parrent::$variable;
    }
}

Ah yes, that's almost what I'm looking for, but wanting to do it the other way - pass the variable from BioController to BasicController. I've got this at the moment, but it doesn't seem to work:

 

abstract class ATCController extends Zend_Controller_Action
{
  public static $tableName = '';

  public function indexAction()
  {
    $this->view->headTitle(ucfirst($tableName));
    $model = $this->_getModel();
    $this->view->content = $model->fetchRow()->Text;
  }

  protected function _getModel()
  {
    if (null === $this->_model) {
      // autoload only handles "library" compoennts.  Since this is an 
      // application model, we need to require it from its application 
      // path location.
      require_once APPLICATION_PATH . '/models/ATCTable.php';
      $this->_model = new ATCTable(array('name' => $tableName));
    }
    return $this->_model;
  }
}

---------------------------

class BiographyController extends ATCController
{
  public function indexAction()
  {
    parent::$tableName = 'biography';
    parent::indexAction();
  }
}

Sorted, in case anyone is interested:

 

abstract class ATCController extends Zend_Controller_Action
{

  abstract protected function _getName(); //to get table name from child classes

  public function indexAction()
  {
    $this->view->headTitle(ucfirst($this->_getName()));
    $model = $this->_getModel();
    $this->view->content = $model->fetchRow()->Text;
  }

  protected function _getModel()
  {
    if (null === $this->_model) {
      // autoload only handles "library" compoennts.  Since this is an 
      // application model, we need to require it from its application 
      // path location.
      require_once APPLICATION_PATH . '/models/ATCTable.php';
      $this->_model = new ATCTable(array('name' => strtolower($this->_getName())));
    }
    return $this->_model;
  }
}

------------------

class BiographyController extends ATCController
{
  protected function _getName()
  {
    return 'biography';
  }
}

if you want to pass a variable to another controller, u can use either of the ff:

_redirect()

_forward()  // works if you want to pass an array

 

 

class BasicController extends Zend_Controller_Action

{

    public function indexAction()

    {

          $name    =  "alex";

          $arrName = array (

              'firsname'  => "myFirstName",

              'lastname => "myLastName");

 

        // if you want to pass variable name:

        //STRUCTURE: controller/action/variableName/value

        $this->_redirect('bio/index/name/$name");

 

        //if you intend to pass an array:

        //STRUCTURE:  'action', 'controller', $array

        $this->_forward('index', 'bio', $arrName);         

    }

}

 

-----------------------------

class BioController extends Zend_Controller_Action

{

    public function indexAction()

    {

        //for sample #1

        $name = $this->getRequest()->getParam(''name');       

    }

}

 

 

 

hope this could help.

True you can do just that but it's the duplicate code that we want to limit. Now I tend to create a controller with all the trimings needed especially if it's going to be the normal "C.R.U.D" structure.  So Check it I would make a controller with like this.

 

Now this is just a shell for it. but the $_model will be called and initialized as the model. Depending on you Model Structure.

 

I tend to not follow Conventional structures but to keep code simple and easy to read for my projects I abstract and refactor repetative code into functions in the controller.

 

I function 1 code 1 fix.

 

class baseController extends Zend_Controller_Action{

  private $_model;

 

  public function init(){}

 

  public function createAction(){}

 

 

  public function editAction(){}

 

 

  public function deleteAction(){}

 

  public function indexAction(){}

 

}

 

 

if you want to pass a variable to another controller, u can use either of the ff:

_redirect()

_forward()  // works if you want to pass an array

 

 

class BasicController extends Zend_Controller_Action

{

    public function indexAction()

    {

          $name    =  "alex";

          $arrName = array (

              'firsname'  => "myFirstName",

              'lastname => "myLastName");

 

        // if you want to pass variable name:

        //STRUCTURE: controller/action/variableName/value

        $this->_redirect('bio/index/name/$name");

 

        //if you intend to pass an array:

        //STRUCTURE:  'action', 'controller', $array

        $this->_forward('index', 'bio', $arrName);         

    }

}

 

-----------------------------

class BioController extends Zend_Controller_Action

{

    public function indexAction()

    {

        //for sample #1

        $name = $this->getRequest()->getParam(''name');       

    }

}

 

 

 

hope this could help.
