Laravel array validation nullifying values

Question

I want to validate the values of an array of objects in Laravel which I pass through the request from the client side (encoded).

First of all, I decode the values passed through the request then validate to check it is null or not.

This is my code

$request->request->set('shopping_list', array_map(function ($arr) {
    return json_decode($arr);
}, $request->shopping));

$validator = Validator::make($request->toArray(), [
    'shopping_list' => ['required'],
    'shopping_list.*' => ['required'],
    'shopping_list.*.store' => ['required'],
    'shopping_list.*.item' => ['required'],
    'shopping_list.*.quantity' => ['required'],
    'shopping_list.*.brand' => ['required'],
    'shopping_list.*.size' => ['required'],
]);

if (count($validator->errors()) > 0) {
    return Response::json($validator->errors()->first(), 422);
}

Unexpectedly the server is returning no error messages. When I return $request->all() or $request->toArray(), after the validation has been done, I am getting the values as follow

If I return it before the validation takes place, I am getting a response like this

How can I fix this issue and validate the items?

Your input is not an array, it is a JSON string. I'm not sure of Laravel by default casts the JSON string to an array then runs the validation or not but that is your issue. — Script47

@Script47 But I am encoding it to an array. Even if it is not an array the validator should return an error message. — Conor

@Conor and if you did return json_decode($arr, true);, does it work? — Script47

As per my suggestion, when using json_decode you can force the JSON string to be returned as associative array by passing true as the second parameter. You were trying to run the validation flags built for arrays on objects.

Note: toArray doesn't convert your JSON to arrays or objects, it simply converts all the properties passed from an object ($request->my_input) to an assoc array.

As a "not good advise". You can call $request->toArray() (and save data in in some variable) before Validator::make(....

That is not making any difference in the output.
