[FX.php List] second find request

[Someone]

Hi guys,
I want do a multiply find request
(
section1=102 and
row1=12 and
seat1=14
)
or
(
section2=102 and
row2=12 and
seat2=14
)

In filemaker you would create a second find request
I couldn't figure it out so I create  calculation fields
zw_ticket1 = section1 & row1 & seat1
zw_ticket2 = section2 & row2 & seat2

	$query->AddDBParam('zw_ticket1', $zw_ticket);
	$query->AddDBParam('-lop', 'or');
	$query->AddDBParam('zw_ticket2', $zw_ticket);
	$queryResult = $query->FMFind();

Any suggestion for a better method welcomed

Frank
