How to order joined results in Phalcon Framework - php

Question

Let's pretend I'm working on a magazine, where a Category (like "sport", "art" an so on) can contain several Articles. Therefore I want to extract all articles for a specific category. In Phalcon I usually do:
$category = \Models\Category::findFirst(array(
'conditions' => 'id = ?1',
'bind' => array(1 => $id)
));
Then:
foreach ($category->Article as $article) {
// do something with $article
}
It works great, but I would like to sort those Articles - say - date wise, ascending. How could I accomplish that?

Answer 1

You should use get prefix in your for..loop statement, so your code should like this :
foreach ($category->getArticle(array('order' => 'date DESC')) as $article) {
// do something with $article
}
The main Docs explains more examples.
Try it & get your results.

Answer 2

M2sh answer is all important and actual, I just will post a secondary way, just using model designed for articles:
$page = 5; // eg. 5th page of results
$limit = 100; // eg. 100 results per page
$articles = \Models\Articles::find(array(
'conditions' => 'category_id = :cid:',
'bind' => array(
'cid' => $id
),
'order' => 'date DESC, id DESC',
'limit' => $limit,
'offset' => $page * $limit
));
It's possible to use such set of parameters in M2sh way aswell.

Answer 3

One more for completeness. I will borrow from yergo to illustrate the differences:
$page = 5;
$limit = 100;
$articles = \Models\Articles::query()
->where('category_id= :cid:', array('cid' => $id)
->orderBy('date DESC, id DESC')
->limit($limit)
->offset($page * $limit)
->query();
