retrieving data from two tables into multidimensional array api json response - php

Question

I am learning Api development where i want to retrieve data from two tables
First table (items) contains:
id, feed_id, title, author, content
Second table (feeds):
feed_id,title,url
I want to get Json response like:
{
- stories :
[
id
feed_id {
title,
url
}
title
author
]
}
My PHP function to retrieve story biased on id is like:
$app->get('/stories/:id', 'authenticate', function($story_id) {
$response = array();
$result = Database::get('db')->table('items')
->eq('rowid', $story_id)
->findOne();
//$response["error"] = false;
if ($result != NULL) {
$response['stories'] = array(
'id' => $result["id"],
'feed_id' => $result["feed_id"],
'title' => $result["title"],
'isBreaking' => $result['isBreaking'],
'author' => $result['author'],
'updated' => $result["updated"],
'url' => $result['url'],
'content' => $result["content"]);
echoRespnse(200, $response);
}
else {
$response["error"] = true;
$response["message"] = "The requested resource doesn't exists";
echoRespnse(404, $response);
}
});
The result i get is like:
{
- "stories": [
{
id
feed_id
title
url
}
]
}
How can i retrieve data from the second tablet (feeds) biased on feed_id and get the data into sub array?

Answer 1

as #MikeBrant mentioned you have to use join between two tables to retrieve correct data. the plain query will be something like this:
select items.id, items.title, items.author, items.content, feeds., feeds.title as feed_title, feeds.url from items left join feeds on items.feed_id = feeds.feed_id
and then change your $response['stories'] like this:
$response['stories'] = array(
'id' => $result["id"],
'feed_id' => array(
'title' => $result["feed_title"],
'url' => $result["url"]
),
'title' => $result["title"],
.
.
.
);
you get the idea :)
