Description:
TMPL_VAR used for same variable both in the loop and outside of the
loop, is empty when used within the loop.
Example: a table of account transactions. In PERL we fill the template
with this code:
my $acct_rec = HTML::Template->new(filename => $args{template});
$acct_rec->param(ACCOUNTID => $args{accountid});
my @loop_data = ();
...
$sth->execute(@args{qw/accountid/}) or die "SQL Error:
$DBI::errstr\n"; ## gets transactions from db
while ($row = $sth->fetchrow_hashref) {
my %tbl_row; # get a fresh hash for the row data
$tbl_row{IS_CHARGE} = ($$row{trxtype} eq 'C') ? 1 : 0;
$tbl_row{TRXID} = $$row{trxid};
$tbl_row{TRXDATE} = $$row{trxdate};
$tbl_row{UNAME} = $$row{uname};
$tbl_row{SNAME} = $$row{sname};
$tbl_row{QUANTITY} = $$row{quantity};
$tbl_row{PRICE} = $$row{price};
$tbl_row{AMOUNT} = $$row{amount};
push(@loop_data, \%tbl_row);
}
$acct_rec->param(TRX_LOOP => \@loop_data);

i.e. ACCOUNTID works outside the loop, inside the loop it stays empty
