Laravel - Too Few Arguements - php

Question

I'm trying to setup a simple button to update a db column value when clicked. I can't seem to figure out why my route isn't getting passed my value however?
HTML:
<form method="post" action="{{ route('approveResturant') }}">
{{ csrf_field() }}
<input type="hidden" name="id" value="{{ $resturant->id }}" />
<button class="btn btn-outline-success" type="submit">
Approve
</button>
</form>
Controller:
public function approveResturant($request)
{
dd($request->all());
$id = $request->id;
$resturant = Resturant::find($id);
$resturant->approved = 1;
$resturant->save;
return redirect()->back()->with('message', 'Resturant Approved Successfully!');
}
Route:
Route::post('approveResturant'[ResturantController::class,'approveResturant'])->middleware(['auth'])->name('approveResturant');
And finally, the error itself:
Any help appreciated!

Answer 1

Add the Request type-hint to your function:
use Illuminate\Http\Request;
public function approveResturant(Request $request)
{
dd($request->all());
$id = $request->id;
$resturant = Resturant::find($id);
$resturant->approved = 1;
$resturant->save;
return redirect()->back()->with('message', 'Resturant Approved Successfully!');
}
The difference here is that Laravel understands the Request type-hint and knows that it should inject the Request object from the pre-defined services it has in its service container. Otherwise, Laravel doesn't know where that parameter is coming from so assumes you will provide it. Simply naming your parameter $request is insufficient.
Update
Do you know why the function would still not be saving the new approved value to the DB?
A few potential reasons:
You have not removed the dd($request->all()); statement
$resturant = Resturant::find($id); failed to find a record in the database
save is a function not a property so $resturant->save; should be $resturant->save();
To isolate the exact issue you will need to perform some debugging (e.g. either using xdebug or dd statements).

Answer 2

Use Request Class
use Illuminate\Http\Request;
public function approveResturant(Request $request)
{
dd($request->all());
$id = $request->id;
$resturant = Resturant::find($id);
$resturant->approved = 1;
$resturant->save;
return redirect()->back()->with('message', 'Resturant Approved Successfully!');
}

Answer 3

<form method="post" action="{{ route('restaurant.approveResturant') }}">
{{ csrf_field() }}
<input type="hidden" name="id" value="{{ $resturant->id }}" />
<button class="btn btn-outline-success" type="submit">
Approve
</button>
</form>
Route::post("/restaurant/store", [RestaurantController::class, "approveResturant"])->name("restaurant.approveResturant");
use Illuminate\Http\Request;
public function approveResturant(Request $request)
{
$restaurant = Restaurant::where("id", $request->input("id"))->update([
"approved" => 1
]);
return redirect()->back()->with('message', 'Restaurant Approved Successfully!');
}
