passing data from controller to model in Joomla 2.5 - php

Question

I am developing a joomla 2.5 component where I need to pass data from controller to model. The controller is receiving data from url. I find that controller is getting the value properly. Now I need to move that value to model from controller. From different post I have found a snippet of code for controller like below.
$datevalue = JRequest::getVar('day',$day); //receiving value from view
$item = JRequest::setVar('day',$datevalue); //setting variable
$model =& $this->getModel('WeeklyProgram'); //assign model
$model->setState('dayVar', $item); // assign value for model
The problem is that I don't know how to receive this value 'dayVar' from model. Can anybody help me on this issue? Thanks.

Answer 1

Use following things
In Modal
class CommunityModelCevent extends JCCModel
{
var $membersCount = null;
function getMembersCount($value) {
$this->membersCount = $value // set your value here 15
// Now you can access this variable into model
}
}
In controller
$ceventModel = CFactory::getModel( 'cevent' );
$membersCount = $ceventModel->getMembersCount(15);

You can do like this . First you make get and set function in the model.Second load the model in the controller and simply pass the values to setter function.Example as follows:
updateratings.php---this is my model
class RatingManagerModelUpdateRatings extends JModelLegacy
{
public $data;
public function get_data(){
$data=$this->data;
return $data;
}
public function set_data($data){
$this->data=$data;
}
}
Controller.php
class RatingManagerController extends JControllerLegacy
{
public function save_ratings(){
$tips = JRequest::getVar('tips'); //get data from front end form
$model = $this->getModel('UpdateRatings'); //load UpdateRatings model
$model->set_data($tips); //update setter function of model
$res=$model->get_data(); // retrieve getter function
//print_r($res);
}
}
