Callsign instead of Flight Number [SOLVED]

[freshJet]

As do a few airlines, we use alphanumeric callsigns on our flights. This is an extra column in the schedules. What I need to do is let kACARS incorporate this. I can already get phpVMS to output the callsign to kACARS so that it is displayed in the flight number box but it does not show on the ACARS map, or in PIREPs.

Doing it in my head gets quite complicated as all I'm trying to do is replace the flight number with the callsign throughout the code, but still using the flight number variable.

Has anyone else done this or know how?

I can now output the callsign in the PIREP, it's now just the ACARS map that won't show it.

I should state that by callsign I mean the callsign of the flight, not the pilot's 'callsign', as others on here refer to it as. In my case, an example is FRX3AR, where 'FRX' is the code, '109' is 'flightnum' and '3AR' is callsign in the schedules.

I have it at last. Wrong use of variable was all it was. It is done using this:

'flightNumber'	 => $biddata->code.$biddata->callsign,
