How to add elements to array in for loop, PHP - Laravel - php

Question

I'm connecting to 3 databases which are stored in array $firmy
For now they are hard coded into array but they will be set via Axios request.
public function show(Request $request, $division, $id)
{
$firmy = array('connection1', 'connection2', 'connection3');
$data = [];
foreach ($firmy as $firma) {
DB::setDefaultConnection($firma);
$calendar = new CalendarEvent();
$data[] = CalendarEventResource::collection($calendar->with('calendarCategories')->where('start', '>', '2020-05-21')->get());
DB::purge($firma);
}
foreach ($data as $firma_event) {
foreach ($firma_event as $event) {
$eventT[] = $event;
}
}
return $eventT;
}
I set the connection, get collection and close the connection.
3 times in this case.
Then I loop through the data to get all records in one go.
Here's the API response returned by $eventT array:
[{"id":17549,"title":"Test","description":"test","contact":"test","email":"test","cat":1,"approved":0,"kto_dodal":450,"calendarCategories":{"id":1,"name":"Ogolna","color":"blue"},"start":"2020-09-30","end":"2020-09-30","private":0,"created_at":null,"updated_at":null},
{"id":17580,"title":"Test","description":"test","contact":"test","email":"test","cat":1,"approved":0,"kto_dodal":450,"calendarCategories":{"id":1,"name":"Ogolna","color":"blue"},"start":"2020-09-30","end":"2020-09-30","private":0,"created_at":null,"updated_at":null},
{"id":17545,"title":"Test","description":"test","contact":"test","email":"test","cat":1,"approved":0,"kto_dodal":450,"calendarCategories":{"id":1,"name":"Ogolna","color":"blue"},"start":"2020-09-30","end":"2020-09-30","private":0,"created_at":null,"updated_at":null}]
One per each connection/table which is fine.
I would like to add a name of the connection to each record. So the API response would look like this:
{"id":17545,"title":"Test","description":"test","contact":"test","email":"test","cat":1,"approved":0,"kto_dodal":450,"calendarCategories":{"id":1,"name":"Ogolna","color":"blue"},"start":"2020-09-30","end":"2020-09-30","private":0,"created_at":null,"updated_at":null, "firma":connection1}]
So "firma":nameOfConnection added to each record.
I tried looping through the data[] and using array_push but I can't place the value of connection inside each record.
Value ends up outside of object:
0: {id: 17549, title: "Test", description: "Test ",…} 1: {firma: "connection1"} firma: "connection1"

Answer 1

I managed to sort it.
First I added a value of firma to Resource class so it gets added to collection although it will be null because there is no column in DB with that name:
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'description' => $this->description,
'contact' => $this->contact,
'email' => $this->email,
'cat' => $this->cat,
'approved' => $this->approved,
'kto_dodal' => $this->kto_dodal,
'calendarCategories' => new CalendarCategoryResource($this->whenLoaded('calendarCategories')),
'start' => $this->start,
'end' => $this->end,
'private' => $this->private,
'created_at' => $this->created_at,
'updated_at' => $this->updated_at,
'firma' => $this->firma,
];
}
Then I access Event collection,loop through the results and set value of firma to whatever value the loop is currently at.
public function show(Request $request, $division, $id)
{
$firmy = array('connection1', 'connection2', 'connection3');
$data = [];
foreach ($firmy as $firma) {
DB::setDefaultConnection($firma);
$calendar = new CalendarEvent();
$data = CalendarEventResource::collection($calendar->with('calendarCategories')
->where('start', '>', '2020-09-21')
->where('private', '=', '0')
->get());
// Loop over data in collection and set value of firma
foreach ($data as $value) {
$value->firma = $firma;
$total[] = $value;
}
DB::purge($firma);
}
return $total;
}
Here's the returned value with the attribute firma inside the object:
{"id":17545,"title":"Test","description":"test","contact":"test","email":"test","cat":1,"approved":0,"kto_dodal":450,"calendarCategories":{"id":1,"name":"Ogolna","color":"blue"},"start":"2020-09-30","end":"2020-09-30","private":0,"created_at":null,"updated_at":null,"firma":"connection1"},
