How to manually map collection using laravel/php and get total amount - php

Question

I currently have the below json response that the API is returning. I am able to return it using Laravel Eloquent. There are several users and each user has a several receipts. A receipt has types and status. I want to try to get the total sum amount for each receipt that is related to its type and status. I was able to return the below json response using
$this->user->with('receipts')->has('receipts')->get(['id', 'name']);
I have tried using multiple laravel collections methods https://laravel.com/docs/5.8/collections#available-methods But I am still unable to get the desired response.
[
{
"id": 1,
"name": "kent",
"receipts": [
{
"id": 1,
"user_id": 1,
"type_id": 1,
"status": 0,
"amount": 100
},
{
"id": 2,
"user_id": 1,
"type_id": 1,
"status": 0,
"amount": 100
},
{
"id": 3,
"user_id": 1,
"type_id": 2,
"status": 1,
"amount": 50
},
{
"id": 4,
"user_id": 1,
"type_id": 2,
"status": 0,
"amount": 30
},
{
"id": 5,
"user_id": 1,
"type_id": 2,
"status": 0,
"amount": 30
},
{
"id": 6,
"user_id": 1,
"type_id": 1,
"status": 0,
"amount": 20
},
{
"id": 7,
"user_id": 1,
"type_id": 1,
"status": 1,
"amount": 10
}
]
},
{
"id": 2,
"name": "allison",
"receipts": [
{
"id": 9,
"user_id": 2,
"type_id": 1,
"status": 0,
"amount": 20
}
]
}
]
I expect to get this:
[
{
"id": 1,
"name": "kent",
"receipts": [
{
"performance and deleted": 220,
"performance and not deleted": 10,
"project and deleted": 60,
"project and deleted": 50
}
]
},
{
"id": 2,
"name": "allison",
"receipts": [
{
"performance and deleted": 20,
"performance and not deleted": 0,
"project and deleted": 0,
"project and not deleted": 0
}
]
}
]
My main concern is to use laravel collection methods and easy to read code to get my expected result

Answer 1

In this way, I believe you get your expected result with nice readable code.
I'll assume that you have $users variable which contains a list of users in collection (And probably the receipts are already loaded).
// You need to name the keys as you desire. (I can't figure out the labels by the type_id and status numbers).
$statusPair = collect([
'performance and deleted' => [
'type_id' => 1,
'status' => 0,
],
'something' => [
'type_id' => 1,
'status' => 1,
],
'something 2' => [
'type_id' => 2,
'status' => 0,
],
'something 3' => [
'type_id' => 2,
'status' => 1,
],
]);
$data = $users->map(function ($user) use ($statusPair) {
$receipts = $user->receipts;
$sums = $statusPair->mapWithKeys(function ($pair, $statusLabel) use ($receipts) {
$filtered = $receipts;
foreach ($pair as $key => $value) {
$filtered = $filtered->where($key, $value);
}
$sum = $filtered->sum('amount');
return [
$statusLabel => $sum,
];
});
return [
'id' => $user->id,
'name' => $user->name,
'receipts' => $sums->toArray(),
];
});

Answer 2

i think this will help
$user->receipts->sum('amount');
