Apps route redirecting the wrong URL - laravel

Question

------Platform Laravel 7x. --------
I am stuck in a simple problem. I can't find the error. While I am updating a form, it redirects to a wrong URL which I don't want and data doesn't update.
Form action url:
method="POST" action="{{'city/update/'. $editCity->id}}"
form image
Route:
Route::post('city/update/{id}','Admin\CityController#update');
web route
Function from controller:
public function update(Request $request, $id)
{
$editCity=City::find($id);
$editCity->city_name=$request->city_name;
$editCity->save();
return redirect()->back();
}
function from controller
When I click on update it goes to this URL and shows 404 error which I don't want:
public/panel/city/edit/city/update/33
Help me to find out the problem where is the mistake I have done. I want to make it updated when I click on the update button and return back.

Answer 1

Use name route instead.
So your code will look like :
blade.php
method="POST" action="{{ route('city.update', $editCity->id) }}"
web.php
Route::post('city/update/{id}','Admin\CityController#update')->name('city.update');

Answer 2

In case your CityController is a resource controller, this what you should try:
Route: web.php
Route::resource('city', 'Admin\CityController');
Form: HTML
<form action="{{route('city.update',$editCity->id)}}" method="post">
Controller: CityController.php
public function update(Request $request, $id)
{
$editCity=City::find($id);
$editCity->city_name=$request->city_name;
$editCity->save();
return back()->with('success','city added successfully!');
}
I hope it helps !

While creating your controller did you run such command ?:
php artisan make:controller Admin\CityController --resource
You should create the controller as a resource controller, then declare it
in your routes like this:
Route::resource('city', 'Admin\CityController');
Ps: Make sure to remove in web.php, your old route:
Route::post('city/update/{id}','Admin\CityController#update')->name('city.update');
