require some suggestion to write trigger function

Hi, could any one please help me with below situation. Thanks for your time
in advance.

I have two tables Foo1(c1,c2,c3) and Foo2(x1,x2,x3). I have written trigger
for Foo1 and it is working fine. The trigger updates the log table when new
insertion happened in Foo1. For this, I have used below code.

CREATE OR REPLACE FUNCTION my_triggert() RETURNS trigger AS $$
$rv = spi_exec_query("insert into logtable VALUES($_TD->{new}{c1},
'$_TD->{new}{c2}','$_TD->{new}{c3}');");
($rv->{processed} == 0 && $rv->{status} eq "SPI_OK_INSERT") ?
elog(INFO, "Success") :
elog(INFO, "Failed");
$$ LANGUAGE plperl;

I have hard coded the columns name c1, c2, c3. Is it possible to get rid of
hard coding c1, c2 and c3 so that I can use same my_trigger function for
Foo2(x1, x2, x3) as well? Any suggestion would be really helpful for me.

Thanks,
Jignesh
