Filter by record with multiple recorded value

Hello!

I have created multiple datafield through category table PROCAT onto the record PROOR. (example: a1,a2,a4) and i need to filter on 4 difference PHP pages, the string that you can see below, look WHERE below.

'where' => "proor = 'a2'", {{only, but not other recorded values}}

but in every page only the selected records from the same table.

<?php
$libraryPath = 'cmsact/lib/viewer_functions.php';
$dirsToCheck = array('/home/acqua/public_html/','','../','../../','../../../');
foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

list($productsRecords, $productsMetaData) = getRecords(array(
'tableName' => 'products',
'where' => "proor = 'a2'",
));

list($houseRecords, $houseMetaData) = getRecords(array(
'tableName' => 'house_comm',
));
$houseRecord = @$houseRecords[0];

list($newsRecords, $newsMetaData) = getRecords(array(
'tableName' => 'news',
));
?>

Please advise,
