Receiving snmp traps with more than one Community String

[ilknurg]

I have the below snmp trap receiver. I have two community string, public and private.
I want to get traps from the devices who has com. string public and private.
In my db my com. strings are:
public
private

My code only get traps from private community strings.
How can i use it with more community strings?
