$query="SELECT * FROM customers";

if(strlen($pram1) || strlen($pram2)) {
$query.=" WHERE ";
if(strlen($pram1)) {
$query.="firstname LIKE '%$pram1%'";
}
if(strlen($pram1) && strlen($pram2)) {
$query.=" AND ";
}
if(strlen($pram2)) {
$query.="town LIKE '%$pram2%'";
}
}

$result=mysql_query($query);


That should fix the problem and only query those things that has been asked
