Validating with all requests - laravel

Question

I have this form:
<form role="form" method="POST" action="{{url('/books')}}">
{!! csrf_field() !!}
<div class="col-sm-5">
<label>Book Name:</label> <input type="text" class="form-control" name="name"><br>
<label>Pages:</label> <input class="form-control" type="text" name="pages"><br>
<label>Price in Rs:</label> <input type="text" class="form-control" name="price"><br>
<input type="submit" class="btn btn-default"><br>
</div>
</form>
And i'm trying to validate if all the form fields are set and not null. similar to isset(). but, else statement is not executed even if submitted without entering values in any inputs. Isn't $request->all() supposed to do so.
public function store(Request $request)
{
if($request->all())
{
$book=new Book();
$book->name=$request->name;
$book->pages=$request->pages;
$book->price=$request->price;
if($book->save())
{
return Response::json(true);
}
else
{
return Response::json(false);
}
}
else
{
return "norequest";
}
}

You can use the ValidatesRequests trait of Laravel.
The code in your store might look like this:
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'pages' => 'required',
'price' => 'required'
]);
// the rest of your code goes here....
}
Here, the above code will accomplish what you want. So, no need to use $request->all() to check if all fields are set and not null.
Hope this helps.
