Custom Form with multilang_shop feature

[Karolukas]

Hello,

 

I'm making a multilang_shop module.

 

In controller I have two forms, first is under renderForm function and second is in custom named function.

 

Second form has language fields. When creating new entry using second form and submitting it, it works fine, submits all data in all languages to database. But when I try editing those entries fields are filled with values,  after editing them and submiting it nothing happens. I tried to search for guides or working examples of forms like this, but haven't had any luck.

 

To make mine forms I used AdminManufacturersController forms as example.

 

EDIT:

 

Prestashop version 1.6.1.16

And module is back-office

 

EDIT2:

Dev mode true I get these errpr:

The previous problem is sorted out. 

 

Now I am stuck with multi language shop row insertion.

 

How to insert language fields for all shops, like it is with products and categories? Now when I insert new row it only adds to the first shop (Selected All shops). But if I select second shop, id_shop is second shops.
