Can't update data in Laravel 8 - php

Question

Currently, I am working on a blog. But when I try to update a post, it's not getting updated and no error is reproduced.
What's wrong with the code? Anyone, please give me some suggestions to improvise my code. I want to understand what's the problem. So, anybody can explain in detail then I will really appreciate this thing.
PostController code:-
public function update(Store $request,Post $post)
{
$data = $request->validated();
$post = $post->update($data);
return redirect('/index')->withMessage('successfully published');
}
View page code:-
<form method="POST" action='/update'>
#csrf
<table class="table table table-striped table">
<div class="form-group">
<label for="name" class="col-form-label text-md-right">Title</label><br>
<input required="required" placeholder="Enter title here" class="" type="text" name="title" class="" value="{{$data->title}}" required/>
</div>
<div class="form-group">
<label for="name" class="col-form-label text-md-right">Description</label>
</div>
<div>
<textarea name="description" class="" required>{{$data->description}}
</textarea></div>
<div>
<input type="submit" name="update" class="btn btn-success" value="Update" required />
</div>
</table>
</form>
Route file code :-
Route::get('posts/edit/{edit}',[PostController::class,'edit']);
Route::post('/update',[PostController::class,'update']);

Answer 1

Change your Route update to this :
Route::post('posts/update',['as'=>'update','uses'=>'PostController#update']);
And in View Page
<form method="POST" action="{{ route('update') }}">
