Har du möjlighet att sätta in koden exakt på hur srchSql och sortWord ser ut?

Visst, så här ser det ut.
Kod:
$srchSql = "SELECT l.legal_case_id, l.header, l.body, l.publish_date, l.summary, lt.name, lt.legal_case_type_id, la.name, la.legal_area_id FROM legal_case l, legal_case_type lt, legal_area la";
$srchSql .= " WHERE l.legal_case_type_id = lt.legal_case_type_id AND l.legal_area_id = la.legal_area_id ";
$ors = 0;
$sortLink = "";
if ($_REQUEST["legal_case_type1"] != '') {
if($ors == 0) {
$srchSql .= " AND (";
} else {
$srchSql .= " OR ";
}
$srchSql .= "l.legal_case_type_id = 1";
$ors++;
$sortLink .= '&legal_case_type1=1';
}
if ($_REQUEST["legal_case_type2"] != '') {
if($ors == 0) {
$srchSql .= " AND (";
} else {
$srchSql .= " OR ";
}
$srchSql .= "l.legal_case_type_id = 2";
$ors++;
$sortLink .= '&legal_case_type2=2';
}
if ($_REQUEST["legal_case_type3"] != '') {
if($ors == 0) {
$srchSql .= " AND (";
} else {
$srchSql .= " OR ";
}
$srchSql .= "l.legal_case_type_id = 3";
$ors++;
$sortLink .= '&legal_case_type3=3';
}
if ($_REQUEST["legal_case_type4"] != '') {
if($ors == 0) {
$srchSql .= " AND (";
} else {
$srchSql .= " OR ";
}
$srchSql .= "l.legal_case_type_id = 4";
$ors++;
$sortLink .= '&legal_case_type4=4';
}
if ($_REQUEST["legal_case_type5"] != '') {
if($ors == 0) {
$srchSql .= " AND (";
} else {
$srchSql .= " OR ";
}
$srchSql .= "l.legal_case_type_id = 5";
$ors++;
$sortLink .= '&legal_case_type5=5';
}

}

EDIT: Missade de sista raderna. Om jag byter till den bortkommenterade raden fungerar det alltså.
Funktionen makeboolean: (Nej, jag kan inte använda fulltextindesk med boolean mode i stället)
Kod:
