How to get DQL result from the template with symfony 1.4? - php

Question

I'm working with symfony 1.4 and Doctrine. I'm writing an app about some pubs/bars, and I've got 4 tables:
products
orders
product_order
pubs.
I want to get the times all products have been ordered in the first pub (i.e. pubs.id = 1). This is what I've got, but I can only get the sum of the first product (products.id = 1) and I need the sum of all of them, in this case there are two different products in my db.
ProductOrderTable:
public function ordersGetCount(){
$q = Doctrine_Query::create()
->from('ProductOrder l')
->innerJoin('l.Order p ON l.id_order = p.id')
->select('SUM(l.amount) as units')
->andWhere('p.id_pub = 1')
->groupBy('l.id_product')
->orderBy('p.id');
return $q->execute();
}
Here my action class:
$this->resultCount= Doctrine_Core::getTable('productorder')->ordersGetCount();
And here my template:
for($i=0; $i<2; $i++){
echo "<tr>";
echo "<td>".$resultCount[0]->getUnits()[$i]."</td>";//
echo "<td>1</td>";
echo "<td>1</td>";
echo "</tr>";
}
Please need help :)

Answer 1

I think there's nothing wrong with your query, but you should have a look at how you display your results.
echo "<td>".$resultCount[0]->getUnits()[$i]."</td>";
Firstly, you're always referring to the first element in the $resultCount array. Secondly, I'm not sure if you can use a getter for a virtual column (you're not using a column which is mapped to your model.
So I would go with something like this:
In the ordersGetCount I would use
return $q->fetchArray();
This will return an array of arrays, not an array of objects, and will allow you to access the virtual column units.
To display the results:
<?php foreach ($resultCount as $row): ?>
<tr>
<td>
<?php echo $row['units']; ?>
</td>
<td>1</td>
<td>1</td>
</tr>
<?php endforeach ?>
EDIT:
This is quite strange ;) Can you try to build the query this way: (in theory it should be the same):
$q = $this->createQuery('l')
->select('l.id_product, sum(l.amount) as units')
->innerJoin('l.Order')
->where('p.id_pub = 1')
->groupBy('l.id_product')
->orderBy('p.id');

Answer 2

You must try remove
->groupBy('l.id_product')
it reduces you results to one product.
