Laravel create custom method to get form data - php

Question

How do I make custom method to get form data? I want this method same with Laravel update method with parameters request and id. I try this but get error.
In controller
public function updatePassword(Request $request, int $id) {
dd($request->all());
}
In route
Route::post('staffs/{id}/upassword', 'Admin\StaffController#updatePassword')->name('admin.staffs.upassword');
In blade file
<form method="post" accept-charset="utf-8" action="{{ action('Admin\StaffController#updatePassword', ['id' => $staff_id]) }}">
<div class="row">
<div class="col-md-3">
<div class="form-group">
<label class="control-label" for="password">New Password</label>
<input class="form-control" name="password" type="password">
</div>
</div>
</div>
<div class="row">
<div class="col-md-3">
<div class="form-group">
<label class="control-label" for="password_confirmation">Confirm New Password</label>
<input class="form-control" name="password_confirmation" type="password">
</div>
</div>
</div>
<input class="btn btn-primary" type="submit">
</form>
I am using Laravel 5.4.

Answer 1

here are some stuff to fix:
First in the tag you can set the action to :
action="route('admin.staffs.upassword', $staff_id)" since it's
easier to write and since you already gave the route a name, so why
not using it ;)
Second add {{csrf_field() }} right before your form closing tag
</form>

Answer 2

what error are you getting? the error is probably because you are not using {{csrf_field()}} after the form declaration, it is needed so that laravel can validate the request. if you want to get the data from the form you can use:
$request->get('inputname');
