i would leave this in separate Models
If i understand you correctly a possible approach could be, to work with collections - below you see an example (i simple wrote it in notepad down now - so there could be some typos - but you should be able to see the point)
Range_Model
PHP Code:
class Range_Model extends CI_Model
{
public function __construct()
{
$this->load->model("Product_Model");
}
public function getItems()
{
//your query to get the ranges
$objCollection = new Range_Collection($query->result("Range_Object"));
$objCollection->addProductCollection($this->Product_Model->getItems());
return $objCollection;
}
}
Product Model
PHP Code:
class Product_Model extends CI_Model
{
public function getItems()
{
//your query to get the products
$objCollection = new Product_Collection($query->result("Product_Object"));
return $objCollection;
}
}
Range Collection
PHP Code:
class Range_Collection extends Array_Object
{
private $arrRangeObjectsByKey = array();
public function __construct($arrObjects = array())
{
parent::__construct($arrObjects);
$this->setRangeArrayByKey($arrObjects);
}
private function setRangeArrayByKey($arrObjects)
{
foreach($arrObjects AS $objRange)
{
$this->arrRangeObjectsByKey[$objRange->range_key] = $objRange;
}
}
public function addProductCollection(Product_Collection $objCollection)
{
foreach($objCollection AS $objProduct)
{
$this->arrRangeObjectsByKey[$objProduct->range_key]->addProduct($objProduct);
}
}
}
Range_Object
PHP Code:
class Range_Object
{
private $objProductsCollection;
public function __construct()
{
$this->objProductCollection = new Array_Object;
}
public function addProduct(Product_Object $obj)
{
$this->objProductCollection->append($obj);
}
public function getProductCollection()
{
return $this->objProductsCollection;
}
public function hasProductItems()
{
return ($this->objProductsCollection->count > 0) ? true : false;
}
}
Product Collection and DataObjects
PHP Code:
class Product_Collection extends Array_Object
{
}
class Product_Object
{
}
your controller
PHP Code:
class Range_Controller
{
public function displayRanges()
{
$this->load->model("Range_Model");
$arrViewData = array(
"objCollection" => $this->Range_Model->getItems()
);
$this->load->view("range_view", $arrViewData);
}
}
and your view
PHP Code:
<table>
<?php
foreach($objCollection AS $objRange)
{
?>
<tr>
<td><?=$objRange->name; ?></td>
<td><?=$objRange->description; ?></td>
<td><?=$objRange->image; ?></td>
</tr>
<?php
if ($objRange->hasProductItems()) :
foreach($objRange->getProductCollection() AS $objProduct) :
?>
<tr>
<td><?=$objProduct->size; ?></td>
<td><?=$objProduct->colour; ?></td>
<td><?=$objProduct->price; ?></td>
</tr>
<?php
endforeach;
endif;
}
?>
</table>
