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

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 functions is there any way for that.

function store(Request $request) 
{
  // some additional logic or checking
  User::create($request->all());
}

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

Referring to Alexey Mezenin answer:

While using his answer, I had to add something directly to the Request Object and used:

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

Using this it adds two variables :

$request[0] = 'variable', $request[1] = 'value'

If you are a newbie like me and you needed an associate array the correct way to do is

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

Hope I saved your some time

PS: Thank you @Alexey, you really helped me out with your answer

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

Example:

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

enough said on this subject but i couldn't resist to add my own answer. I believe the simplest approach is

request()->merge([ 'foo' => 'bar' ]);

You can also use below code

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

Fits better for me.

In laravel 5.6 we can pass parameters between Middlewares for example:

FirstMiddleware

public function handle($request, Closure $next, ...$params)
{
    //some code
    return $next($request->merge(['key' => 'value']));
}

SecondMiddleware

public function handle($request, Closure $next, ...$params)
{
    //some code
    dd($request->all());
}

simply use this:-

$request->merge(['index' => 'value']);

work for me

This will add a new value to your request object with the given index and use can use it in your function or while saving all request data into the database.

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]);
}

Tag: laravel5.8.11

To add a new parameter for ex: newParam to the current Request Object, you can do:

$newParam = "paramvalue";
$request->request->add(['newParam' => $newParam]);

After adding the new parameter, you would be able to see this newly added parameter to the Request object by:

dd($request);//prints the contents of the Request object

I used this code to add something to my request.

$req->query->add(['key'=>'variable']);
$req->request->add(['key'=>'variable']);

you can use laravel helper and request() magic method ...

request()->request->add(['variable1'=>'value1','variable2'=>'value2']);

You can access directly the request array with $request['key'] = 'value';

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 add parameters to the request from a middleware by doing:

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

If you would like to add a query param to the Request object that can be obtained by calling

$request->get('key') 

OR

$request->all()

The following works well for me.

$request->query->set('key','value');

You can also do $request['key'] = 'value'; on newer Laravel versions.
