Laravel 5.1 - Store input data in my session - php

Question

I have a view show.php of my single product, when user click on ADD PRODUCT my controller CartController.php update my session cart and update my cartSession table,
Now i'm tryng to put new data (Color input,Size input, Quantity input) on my session and also in my CartSession table. But i dont know why it doesn't work.
-I think that the principal problem is that $request->get('input') doesn't pass to my CartController.php , i tried to return
$request->all() and there is not nothing.
CartController.php
namespace dixard\Http\Controllers;
use Illuminate\Http\Request;
use dixard\Http\Requests;
use dixard\Http\Controllers\Controller;
use dixard\Product;
use dixard\CartSession;
use dixard\CartItem;
use dixard\Shipping;
use Session;
// i think that all classes are ok
public function add(Product $product, CartSession $CartSession,Request $request)
{
$id = $request->get('id');
$cart = \Session::get('cart');
$product->quantity = $request->get('qty');
$product->size = $request->get('size');
$product->color = $request->get('color');
$cart[$product->id] = $product;
\Session::put('cart', $cart);
return $request->all(); // here i tried to get all inputs but it shows me nothing result
$subtotal = 0;
foreach($cart as $producto){
$subtotal += $producto->quantity * $producto->price;
}
$session_code = Session::getId();
$CartSession = new CartSession();
$session_exist = CartSession::where('session_code', $session_code)->orderBy('id', 'desc')->first();
if (isset($session_exist)) {
$s = new CartSession;
$data = array(
'subtotal' => $subtotal,
);
$s->where('session_code', '=', $session_code)->update($data);
}else {
$CartSession = new CartSession();
$CartSession->session_code = $session_code;
$CartSession->subtotal = $subtotal;
$CartSession->save();
}
//return $cart;
//salveremo tutte le informazioni nel array cart nella posizione slug
foreach($cart as $producto){
$this->saveCartItem($producto, $CartSession->id, $session_code, $cart);
}
return redirect()->route('cart-show');
}
Routes.php
Route::bind('product', function($id) {
return dixard\Product::where('id', $id)->first();
});
Route::get('cart/add/{product}', [
'as' => 'cart-add',
'uses' => 'CartController#add'
]);
show.php view
Get Data about the product is ok, title, description, color avaible, price ecc. all information pass to my view.

Thank you for your help!

Answer 1

You have to explicitly set the post-method to be "get" or you need to change your router to accept the request as post. Even though you're calling the route by name, Form::open defaults to "POST"
https://laravelcollective.com/docs/5.2/html#opening-a-form
Option 1. Change
Route::get('cart/add/{product}',...
to
Route::post('cart/add/{product}',...
Option 2. Change
{!! Form::open(['route'=> ['cart-add', $product->id],'class'=>'form-horizontal form-label-left'])!!}
to
{!! Form::open(['method'=>'GET', 'route'=> ['cart-add', $product->id],'class'=>'form-horizontal form-label-left'])!!}
