Я новичок в PHP, MySQL, и я тренировался в бинарном проекте MLM. Проблема заключается в том, что я хочу реализовать в этой системе MLM вторичную систему, чтобы, если у пользователя root дерева уже было два дочерних элемента «ВЛЕВО» и «ВПРАВО», и если он отсылает другого пользователя влево, то go левый пустой левый дочерний элемент, и если он направляет нового пользователя вправо, то он должен go к правому пустому правому дочернему элементу.
Я пробовал много примеров функций из StackOverflow и других ресурсов, но я не сделал t найти результат.
Вот таблица базы данных user ('id' является первичной и AI):
___________________________________
|id |userid | sponser_id | side |
___________________________________
|1 | 11111 | 0 | root |
|2 | 22222 | 11111 | left |
|3 | 33333 | 11111 | right |
___________________________________
Вот таблица базы данных tree ('id' является первичным и 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 |
__________________________________________________________________
Теперь, если userid 11111 ссылается на нового члена слева, тогда он должен go под 33333.
Вот регистр. php код:
