Slim query parameter - php

Question

I want to add a query parameter in my GET Route, which is this one:
$app->get('/rooms', function (ServerRequestInterface $request, ResponseInterface $response, $args) {
try {
$room = new \Riecken\PBS\controller\RoomController();
$result = $room->getRoomsWithDetails();
$response = $response->withJson($result);
$response = $response->withStatus(200);
return $response;
}catch(Exception $e) {
$response->getBody()->write($e->getMessage());
return $response->withStatus($e->getCode());
}
});
What I want to do is that I only want to execute this function when I type "expandAll".
I googled it and I could find something in the Slim documentation:
https://www.slimframework.com/docs/v3/objects/request.html
But I dont know how to implement it.
So in my case:
If "expandAll" I want to execute the function you see above (getRoomWithDetails(), else I want to execute another function.
Is that possible?
Thanky you very much!

Answer 1

You could just pass the required query parameters to getRoomsWithDetails or you just add a if condition.
Example
$app->get('/rooms', function (ServerRequestInterface $request, ResponseInterface $response, $args) {
try {
$expandAll = $request->getParam('expandAll');
$room = new \Riecken\PBS\controller\RoomController();
if ($expandAll) {
$result = $room->getRoomsWithDetails();
} else {
$result = $room->anotherMethod();
}
$response = $response->withJson($result);
$response = $response->withStatus(200);
return $response;
} catch(Exception $e) {
$response = $response->withJson(['error' => ['message' => $e->getMessage()]]);
return $response->withStatus(500);
}
});
