[TYPO3] itemsProcFunc - selectbox array - howto?

[VINCNET/CMSRepublic]

 (sorry for posting this twice - first attempt through the newsreader didn't
get listed on the website)

Hi list,

I want to pass data from a foreign table to a "main" table. The data in the
foreign table can be included from a backend "main" form by a selectbox. But
also the data can be entered from the "main" form. So the selectlist is not
fixed, it's extendible by the content managers just by adding selectable
data on the fly.

My trouble begins where just the UID is passed to the main table. But I need
the value from another field to be passed.

I understand that this is done by a itemsProcFunc (is it?), but since my PHP
is not that good (and my PHP-programmer gave birth yesterday to a nice
little girl so she has other things to do) and I also cannot find any
examples or complete documentation of it, I don't know how to do this.

Can someone get me on the right track? Been trying and searching for at
least 6 hours, so... my hope is on the list;-) An example would be great, or
otherwise some assisance today or tomorrow. You can send me a bill if
necessary (after short negotiations that is).

Some more info:

* the leading table, where all data is collected, is named "programs", and
has a field called "meta_station";
* the foreign table is called "stations", and has a field named
"station_name";
* my purpose is to get the data from "station_name" (and not from "uid")
into "meta_station".

Perhaps you want to know why I want this? The main table might be easier to
search through (on datastrings) and also this main table might be opened for
external situations.

Greetz and thanks,
Vincent
