Ah I see. Thank you very much.
Having gone back and reading you post now, it's all much clearer. I
probably should have carefully read your post again before posting and
I might have been able to figure that one out on my own.
So now what I have is an array that I have to re-organize in my
controller so that it will work with saveAll. I need to change it
from
'model name'
'Field Name'
'index' -> data
to
'model name'
'index'
'field names' -> data
Correct? I want to make sure I have the right idea here
Thanks Again.
