I took a look at this patch, and I concluded that the passing of other
information needed to more generic. So not so much just being able to
pass a node.
One thing that I would like to see is targeted filters so that you can
have a filter which will only be applied to nodes, and other filters
which will be applied to other types of data which is being filtered.
I was actually looking to using the filtering for the E-Commerce emails,
but it was just too node centric.
Doing this then you can set up to allow the passing of an array of
parameters which could then used by the filter. In the case of the php
filter you could extract() the array and use all the parameters as local
Also it means that filters could be targeted, ie. can be used for nodes
or any other type of data, or global like what there is now, and not
care what the data is.
Also this will change the filter_tips and only show filters which are
applicable to the type of data that is being filtered.
I plan on doing this one day when I have time. It will make the
filtering system a lot more powerful.
