问题
I am new to PHP, MySQL and I was practicing on a binary MLM project. The problem is, I want to implement spillover system in this MLM system so that if root user of the tree already has two child "LEFT" & "RIGHT" and if he refers another user to left then it should go to the left empty child's left side and if he refers the new user to right then it should go to the right empty child's right side.
I have tried many function examples from StackOverflow and other resources but I didn't find the result.
Here is the database table user ('id' is primary and AI):
___________________________________
|id |userid | sponser_id | side |
___________________________________
|1 | 11111 | 0 | root |
|2 | 22222 | 11111 | left |
|3 | 33333 | 11111 | right |
___________________________________
Here is the database table tree ('id' is primary and AI):
__________________________________________________________________
|id |userid | left_child | left_child | right_count| right_count |
__________________________________________________________________
|1 | 11111 | 22222 | 33333 | 1 | 1 |
|2 | 22222 | NULL | NULL | 0 | 0 |
|3 | 33333 | NULL | NULL | 0 | 0 |
__________________________________________________________________
Now if userid 11111 refers a new member to left then it should go under 33333.
Here is the register.php code:
<?php
include('php-includes/connect.php');
include('php-includes/check-login.php');
include('ajaxuser.php');
include('php-includes/functions.php');
$userid = $_SESSION['userid'];
$capping = 5;
