Zend2 combine tablegateway array - sql

Question

I'm new to Zend2, and want to combine two tablegateway objects
I have two tables: prices and sizes. Every price has multiple sizes.
I want to join these tables into an array, so I can list the prices with the sizes in it.
For example:
array(
1 => array(
'price' => 45,
'description' => 'Lorem ipsum',
'sizes' => array(
1 => '16',
2 => '17',
3 => '20',
4 => '21'
)
),
2 => array(
'price' => 50,
'description' => 'Lorem ipsum',
'sizes' => array(
1 => '34',
2 => '12',
3 => '21',
4 => '50'
)
)
)
My PricesTable.php:
public function getPricesbyJewel($jewel)
{
$rowset = $this->tableGateway->select(array('jewelid' => $jewel));
return $rowset;
}
My SizesTable.php
public function getSizesbyPrice($price)
{
$rowset = $this->tableGateway->select(array('priceid' => $price));
return $rowset;
}
How I list the prices (so without the sizes in it)
$jewelPrices = array('jewelryPrices' => $this->getPricesTable()->getPricesbyJewel($jewel->id));
$jewelSizes = array('jewelrySizes' => $this->getSizesTable()->getSizesbyPrice($priceID);
How to list the sizes into the prices as an array of those tables in the controller?

Answer 1

Fixed it with an inner join:
PriceTable.php
public function getPricesbyJewel($jewel)
{
$sql = new Sql($this->tableGateway->getAdapter());
$select = $sql->select();
$select->from('jewelry_prices')
->join('jewelry_sizes', 'jewelry_prices.id=jewelry_sizes.priceID')
->where('jewelry_prices.jewelid='.$jewel);
$resultSet = $this->tableGateway->selectWith($select);
return $resultSet;
}
Controller:
$prices = array('jewelryPrices' => array());
foreach($this->getPricesTable()->getPricesbyJewel($jewel->id) as $key => $price){
if(!array_key_exists($price->priceID, $prices['jewelryPrices'])){
$prices['jewelryPrices'][$price->priceID] = array(
'orderNote' => $price->orderNote,
'price' => $price->price,
'description' => $price->description,
'sizes' => array()
);
array_push($prices['jewelryPrices'][$price->priceID]['sizes'], $price->size);
} else {
array_push($prices['jewelryPrices'][$price->priceID]['sizes'], $price->size);
}
}
