hello every one

i have a Category model and its have only name and image field

so for making a new category its work fine

but when its come to update

i have a small issue

i make the code work like this :-

1 - if the user upload a file then it will take the file and put the path on the field 2 - if not then it will grab the previous value of the image field and put it in the field

the problem with the first step

its upload the file but its return an empty value in the image field and dosnt update it !!

this is my code

http://laravel.io/bin/eDDkn#17-18

i try to use

$request->merge([ 'image' => public_path().'/images/categories/'.$image;, ]);

but same thing

it always give me this response

{ "id": 1, "name": "Small Car2", "created_at": "2015-05-21 12:51:11", "updated_at": "2015-05-22 08:14:11", "image": {} }

as the image : {}

and btw even when the field not updated the file was upload and move successfully
