Q:

BASH - post array with "wget --post-data"

I need to download an xls table from a url that require two arrays as parameters.
First orderids.
Second columns.
For every order i have that columns.
wget --load-cookies cookies.txt \
        --post-data='orderids=xxxx,xxxx,xxxx&columns=x,x,x,x,x' \
     https://www.url.com/createordersexcel

In this way i get only first value inserted

A:

That wget command looks OK, and worked in a small test I did. 
Your problem is probably on the server side.
