Passing a variable between two controllers using session

Hello Laracasts community, I have got two controllers(ProductsCobttroller and FrontController) in my Laravel 5.4 project, The ProductsController is a CRUD and am using the show function to fetch image name from products table and store in a variable. Now I want to pass the variable to a view called front.blade.php which is controlled by FrontController. Am try to use sessions to achieve the task but I keep getting errors. Please assist?

ProductsController

public function show($id)
    { 
        $items = Category::find(6)->products()->where('image' , true)->get();

         Session::put('item', $items);
        
    }

FrontController

 public function index(){
        Session::get('item');
       return view('front.index' , compact('item'));
    }

Routes

Route::group(['middleware' => 'web'], function () {
    Route::get('/' , 'FrontController@index')->name('front.index');
});

Front.blade.php

@foreach($item as $items)
    <img src="{{ asset('images/'.$items->image) }}">
@endforeach

public function index(){
        $item = Session::get('item');
       return view('front.index' , compact('item'));
    }

(I'm not 100% sure why you're using the session to do this, I'm assuming you are doing something more complicated than this but you've vastly simplified the example)

Ok Jack, I am trying to pass the variable from the ProductsController to the FrontController so that I can use it in fron.blade view. Am not sure if that is the way to use Session to pass variables between controllers...?

What you are doing is not conventional. Does the ProductsController@show action have any other side effects; does it return a view?

Why not simply get the items in the FrontController@index action?

@tykus Now thats the bone of contention, I am tying to get elements of a particular id from the database and I opted to use the productsController then pass the variable to the frontController. How can I use the frontcontroller@index to get the products of a particular id? ..Regards

Just a quick recap of my project: I am creating an e-commerce project whereby I have added images to a database and have used one to many relationship to sort them(many categories have one product), Every function in the ProductsController(a CRUD) works fine. Now I want to fetch images of a particular category and display to a view called Front.blade.php.... How can I go about achieving that using the frontController ?
