Laravel is there a way to add values to a request array

Question

I come across a situation in Laravel while calling a store() or update() method with Request parameter to add some additional value to the request before calling Eloquent fu

Answer 1

I tried $request->merge($array) function in Laravel 5.2 and it is working perfectly.

Example:

$request->merge(["key"=>"value"]);

Answer 2

Based on my observations:

$request->request->add(['variable' => 'value']); will (mostly) work in POST, PUT & DELETE methods, because there is value(s) passed, one of those is _token. Like example below.

<form action="{{ route('process', $id) }}" method="POST">
    @csrf
</form>

public function process(Request $request, $id){
    $request->request->add(['id' => $id]);
}

But [below code] won't work because there is no value(s) passed, it doesn't really add.

<a href='{{ route('process', $id) }}'>PROCESS</a>

public function process(Request $request, $id){
    $request->request->add(['id' => $id]);
}

When using GET method you can either declare Request and assign value(s) on it directly. Like below:

public function process($id){
    $request = new Request(['id' => $id]);
}

Or you can use merge. This is better actually than $request->request->add(['variable' => 'value']); because can initialize, and add request values that will work for all methods (GET, POST, PUT, DELETE)

public function process(Request $request, $id){
    $request->merge(['id' => $id]);
}

You can add parameters to the request from a middleware by doing:

public function handle($request, Closure $next)
{
    $request->route()->setParameter('foo', 'bar');
    return $next($request);
}

Answer 4

Usually, you do not want to add anything to a Request object, it's better to use collection and put() helper:

function store(Request $request) 
{
    // some additional logic or checking
    User::create(array_merge($request->all(), ['index' => 'value']));
}

Or you could union arrays:

User::create($request->all() + ['index' => 'value']);

But, if you really want to add something to a Request object, do this:

$request->request->add(['variable' => 'value']); //add request

Answer 5

The best one I have used and researched on it is $request->merge([]) (Check My Piece of Code):

    public function index(Request $request) {
        not_permissions_redirect(have_premission(2));
        $filters = (!empty($request->all())) ? true : false;
        $request->merge(['type' => 'admin']);
        $users = $this->service->getAllUsers($request->all());
        $roles = $this->roles->getAllAdminRoles();
        return view('users.list', compact(['users', 'roles', 'filters']));
    }

Check line # 3 inside the index function.

You can also use below code

$request->request->set(key, value).

Fits better for me.
