laravel request is undefined - angularjs

Question

I am a newbie in Laravel, so everything is under exploration period. I use angular http post to send data over to laravel and in laravel controller i am able to
dd($request)
Request {#40
#json: ParameterBag {#32
#parameters: array:4 [
"GPTour_id" => 1
"customer_id" => 1
"status" => "Confirmed"
"note" => "asdfasdf"
]
}
#userResolver: Closure {#300
class: "Illuminate\Auth\AuthServiceProvider"
this: AuthServiceProvider {#22 …}
use: array:1 [
"$app" => Application {#3
#basePath: "/Users/haophung/Dropbox/server/websites/nglaravelyep/laravel-backend"
#hasBeenBootstrapped: true
#booted: true
#bootingCallbacks: []
However, if i use
$request->input('key')
i got $request is undefined. Please advise!!!
public function addGospelCustomer(Request $request)
{
if ($request) {
$customer_id = $request->get('customer_id');
$tour_id = $request->get('GPTour_id');
$validator = Validator::make($request->all(), [
'customer_id' =>'required'
]);
if ($validator->fails()) {
return response()->json(['error' => $validator->errors()], 406);
}
$gospel_customer = Gospel_tour::find($tour_id)->with(['customers' => function($query) {
$query->where('id', $customer_id);
}])->first();
if ($gospel_customer === 'null') {
return response()->json(['error' => "The Customer is already on the list"], 406);
}
return 'success';//response()->json(['success' => $request], 200);
}else {
return response()->json(['error' =>'can not add customer'], 401);
}
}
ErrorException in GospelController.php line 60:
Undefined variable: customer_id
I think the problem is
$gospel_customer = Gospel_tour::find($tour_id)->with(['customers' => function($query) {
$query->where('id', $customer_id);
}])->first();
I can echo $customer_id out, but in this eloquent is not defined

Answer 1

You need to typehint requestion in your function definition
public function name(Request $request) {}
And use it like
$key = $request->key;
$key = $request->get('key');
Or use the global function
$key = request('key');
Update
Where you have the error exception do
$gospel_customer = Gospel_tour::find($tour_id)->with(['customers' => function($query) use ($customer_id) {
$query->where('id', $customer_id);
}]);
The error occurs because you are inside a closure, and it doesn't have access to external variables.
