Why is my data not being submitted into the database - php

Question

I tried to create adding/creating a new menu and saved it in the database. However, when I clicked the button, my system didn't show any error but the data is not saved in the database.
adminAddMenu.blade.php
<form>
#csrf
<div class="form-group row">
<label for="categorycode" class="col-sm-3 col-form-label">Category Code</label>
<div class="col-md-4">
<input name="category_code" value="{{old('category_code')}}" class="form-control">
</div>
</div>
<div class="form-group row">
<label for="menutitle" class="col-sm-3 col-form-label">Menu Title</label>
<div class="col-md-4">
<input name="menu_title" value="{{old('menu_title')}}" class="form-control">
</div>
</div>
<div class="form-group row">
<label for="menuprice" class="col-sm-3 col-form-label">Menu Price</label>
<div class="col-md-4">
<textarea name = "menu_price" value="{{old('menu_price')}}" class="form-control"></textarea>
</div>
</div>
<div class="form-group row">
<div class="offset-sm-3 col-sm-9">
<button type="submit" class="btn btn-primary" href="">Submit</button>
</div>
</div>
</div>
</form>
AdminMenuController.php
public function store(Request $request)
{
$menu = new \App\Menu;
$menu->category_code = $request->category_code;
$menu->menu_title = $request->menu_title;
$menu->menu_price = $request->menu_price;
$menu->save();
Session::flash('flash_message', 'Menu is successful! added');
return redirect()->back();
}
web.php
Route::resource('/menus', 'AdminMenuController');

Answer 1

You don't give the form action method where your data will submit. Like you want to send your form data to store method in your controller. So you have to write follow:
<form method="POST" action="{{ route('your route name') }}">

Answer 2

I think you miss the action attribute of your form. Please add action to your form
<form action="{{ YOUR_ROUTER }}">
...

Answer 3

Please add action on form tag.
Like as-
<form action={{ route("your route write here") }} method="post">
I think now it's work's.
