Orders/SaveOrders/paypal

hi friends! I am following a laravel 5.2 tutorial, but I am using laravel 5.4.6, so I have so many problems...

I am now trying to create an order detail view in the admin pannel with the help of main.js and ajax.

The complementation seems to work correctly. The problem, it seems, is in the part of saving the order; This method I carry through paypal and its controller: apparently when saving the order this does not save the name or the image ...

Then when I call these two factors of the items in my modal; I get as 'name' I get 'undefined' and as image 'broken'
