Question

Hi, I have a question, when i ever insert this code
if ($pointsreach>=$tempunilevel ){
mysql_query("UPDATE `incentives_table` SET pointsreach = pointsreach +500 where userid = '$newsponsorid' ");
the if statement does not work anymore
if (count($items) >0 && $lev <= 10 ){ // found get sponsor id for the next computation
$sponsorid = $items->upline; //sponsor id
but when i remove the
if ($pointsreach>=$tempunilevel ){
mysql_query("UPDATE `incentives_table` SET pointsreach = pointsreach +500 where userid = '$newsponsorid' ");
the statement works perfectly ...
$query = " UPDATE `#__eds_incentives_table` SET `temp` = `temp` + 25 where `userid` = '$sponsorid' ";
$db->setQuery($query);
$db->query();
$mote = $this->entryuni($sponsorid, $lev + 1, +25);
}
else {
return 'ok';
}
This is the code
public function entryuni($newsponsorid = null, $lev = 2, $fpv = 0)
{
$db = & JFactory::getDBO();
$query = "SELECT upline,fslot FROM `table` where userid = '$newsponsorid' ";
$db->setQuery($query);
$items = $db->loadObject();
$items = (!empty($items)) ? $items : array();
$queryreach = mysql_query("SELECT * FROM incentives_table WHERE userid = '$newsponsorid' ");
$fetchreach = mysql_fetch_array($queryreach);
$pointsreach=$fetchreach['pointsreach'];
$tempunilevel=$fetchreach['temp_unilevel'];
if ($pointsreach>=$tempunilevel ){
mysql_query("UPDATE `incentives_table` SET pointsreach = pointsreach +500 where userid = '$newsponsorid' ");
if (count($items) >0 && $lev <= 10 ){ // found get sponsor id for the next computation
$sponsorid = $items->upline; //sponsor id
$query = " UPDATE `#__eds_incentives_table` SET `temp` = `temp` + 25 where `userid` = '$sponsorid' ";
$db->setQuery($query);
$db->query();
$mote = $this->entryuni($sponsorid, $lev + 1, +25);
}
else {
return 'ok';
}
