I’ll try keep this question as simple as possible:
#FRONTEND :
[LIST=1]
[]User selects items (from predefined list): “itemx, itemy”
[]database is updated.
[*]cycle is repeated.
[/LIST]
#BACKEND
[LIST=1]
[]php enters itemx, itemy into database (single entry).
[]php should find out what components of itemx, itemy are (stored in another table, with key as itemid)
[*]increment use of componentx, componenty of respective item.
[/LIST]
please do help, i know this is a little confusing, but if you are able to, i’ll be most grateful to you! please do ask if something is not clear.
