For calculating numbers of downline in binary tree, I am trying the following script by making 2 databases for registration and members downline structure. It works actually.
This is the answer after I try many ways. Solving my previous problem. Just using a single member table above.
To show number of downlines, left and right. I insert this script in the HTML member tree page for every user in the tree A, down to B/C, down to D/E/F/G ):
<?php echo $users->downline_number($member,'_left'); ?>
<?php echo $users->downline_number($member,'_right'); ?>
Add this function in User Class ;
function downline_number($member,$position) {
$query = $this->db->prepare("SELECT * FROM `member` WHERE `upline`='$member' AND `position`='$position'");
$query->bindValue(1, $member);
$query->bindValue(2, $position);
try{
$query->execute();
$rows = $query->fetch();
if($this->count_downline($member,$position) >0 ){
$total=$this->total_members_down($rows['username']);
}else{
$total=0;
}
return $total;
}catch(PDOException $e){
die($e->getMessage());
}
}
function count_downline($member,$position) {
$query = $this->db->prepare("SELECT * FROM `member` WHERE `upline`=? AND `position`=? ");
$query->bindValue(1, $member);
$query->bindValue(2, $position);
try{
$query->execute();
return $rows = $query->rowCount();
}catch(PDOException $e){
die($e->getMessage());
}
}
function total_members_down($upline,$reset=0) {
global $num;
if ($reset==0) { $num=1; }
$query = $this->db->prepare("SELECT * FROM `member` where `upline`='$upline' order by id asc");
$query->bindValue(1, $upline);
try{
$query->execute();
if ($upline !='') {
if ($this->total_down($upline) > 0 ) {
while ($rows = $query->fetch() ) {
$num++;
$this->total_members_down($rows['username'],$num);
}
return $num;
} else {
return $num;
}
} else { $num=0; return $num; }
}catch(PDOException $e){
die($e->getMessage());
}
}
function total_down($upline) {
$query = $this->db->prepare("SELECT * FROM `member` where `upline`='$upline' order by id asc ");
$query->bindValue(1, $upline);
try{
$query->execute();
return $rows = $query->rowCount();
}catch(PDOException $e){
die($e->getMessage());
}
}
and it works showing binary member tree structure. Showing the memberID is not attached here, caused it simple way. Just left & right downlines number.
Hope this post will help others who need it. Any suggestion for better ways?
