Adding Conditional Where to PHP Code

I have some PHP code which works today. I am trying to add some more predicates to the WHERE clause.? The new ones do not work.? The code is below. ? I have highlighted the nonworking statements.? Entire test installation with mySQL installation is attached.? This PHP is TCPTerm1.php. Instructions to install are in the attached zip file. <?php $LocIpAddr=$_GET["LocIpAddr"]; $RmtIpAddr=$_GET["RmtIpAddr"]; If ($LocIpAddr == "") $LocIpAddr = "%"; If ($RmtIpAddr == "") $RmtIpAddr = "%"; $LocPortSingleFld=$_GET["LocPortSingleFld"]; $LocPortWhere = ""; If ($LocPortSingleFld == "") ? ? {? $LocPortWhere = ""; ? ? } Else ? ? { $LocPortWhere = "And TTLPORT=" . $LocPortSingleFld . "; ? ? ? ? echo $LocPortWhere; ? ? ? } $con = mysql_connect("localhost","root",""); if (!$con) { ? $ErrMsg = "{"; ? $ErrMsg = $ErrMsg . "ErrMsg: "; ? $ErrMsg = $ErrMsg . "'Houston we have a problem!!'"; ? $ErrMsg = $ErrMsg . "}"; ? echo $ErrMsg; ? exit(0); } $arr = array(); mysql_select_db('DBITS200'); $Query = "Select ? ? ? ? ? ? ? ? ? ? ? TTEDATE, ? ? ? TTETIME, ? ? ? TTLIP, ? ? ? TTLPORT, ? ? ? TTRIP, ? ? ? TTRPORT, ? ? ? TTINBYTES, ? ? ? TTOUTBYTES, ? ? ? TTTERMCODE, ? ? ? Case TTTERMCODE ? ? ? ? When 82 Then 'APP CLOS' ? ? ? ?

". $LocPortWhere ."; $ResultSet = mysql_query($Query); while($obj = mysql_fetch_object($ResultSet)) { ? $arr[] = $obj; } echo json_encode($arr); mysql_close($con); exit(0); ?>
