I'm creating a new view for a personalized POS module for my restaurant. It's a specific view for kitchen, already filtered to show just kitchen's related items of a POS order.
Now I would like to show a particular series of product with the name starting with "#" as a unique in a column populated by a new field side by side with the "standard" products. In fact I'm speaking of a set of instructions coded as products to be available on POS and since I was unable to edit the js and css of the pos for suit my needs I decided to create kitchen instructions as a product (service). In my POS there are 3 categories that are not products but instructions (ADD, SUBTRACT, ADDITIONAL NOTE).
What I would like to archive is a view like:
| Product | Note | Quantity |
| [1007] Pom. Secchi | # + Búfala # - Mussarela | 1 |
| [2002] Nutella banana | # + Mussarela | 1 |
| [3002] Fanta Uva 350ml | 1 |
The original view is:
| Product | Category | Quantity |
| [1007] Pom. Secchi | Piadine | 1 |
| # + Búfala | Extra-Rid | 1 |
| # - Mussarela | Extra-Rid | 1 |
| [2002] Nutella banana | Piadine Dolci | 1 |
| # + Mussarela | Extra-Rid | 1 |
| [3002] Fanta Uva 350ml | Bebida | 1 |
I know I can group field values in a unique, new field with fields.function(_get_concatenate_values) but my problem is how to filter the products before write them respecting the id sequence for the new view. Other than this I need to select just the "#" product between two internal code starting with "[code]" and this is the hard thing to do.
Someone could gently drive me to the right direction?
EDIT:
I can see added pictures on my post during creation/edit but not when I save the post. Is because I don't have enough Karma?
