To create 2 or more Additional fields, this is what I did:
Created a new Copy of “eshop-extras” plugin, and changed the folder name and the plugin name (plugin name at firts lines on the .php file).
On the .php file:
Change every instance of “eshop_extra” for “eshop_extra2”.
Activate the “new” Plugin in WordPress Admin
Voila! New field added on database, checkout form and every other place.
Hope it helps someone else.
Have a nice day!
well it seems it had nothing to do with permalinks.
the problem was one of the $_POST variables was creating some conflict, maybe it was ‘name’, ’email’ or another one. I just changed all of their names and now it’s working fine.
posting this just in case someone would come across my post 😉
long live wordpress 😛 lol wtf x)
