Re: [Apc-aa-coders] Creating an instance of class item

[Mitra <mi...@mi...>]

So should we have a generic function that takes an itemid, reads the 
aliases from the slice's info, and then the content from the db and 
then creates an item?

That function itself is easy, but needs two functions to make it work i.e.


$aliases =3D slice_aliases($sliceid);
$content =3D read_content_from_db($itemid);
new $item("","",$aliases,"","");
$item->columns =3D read_content_from_db($itemid);

I don't think the format string is needed? Since we are going to be 
expanding a view.

The two functions I'm using above - i.e. slice_aliases($sliceid) and 
read_content_from_db($itemid) both seem to be missing, although they 
both seem pretty generic to me.
