如何在PHP中构建引荐系统? [英] How can I build a referral system in PHP?

问题描述

我有一个带有推荐系统的网站，我希望用户能够使用树视图查看他们所推荐的用户.

设置我的数据库表，以便当用户使用其推荐代码推荐某人时， 新用户会获得一个ID，一个赞助商代码(来自他的发起人"的推荐代码，又称他为访问此网站的人)和一个推荐代码(他自己的推荐代码，以吸引其他人加入他的行列).

我不知道如何从MySQL数据库中获取此信息，并导入到树视图脚本中.

我需要使用户能够看到他所介绍的所有人员(十层深).

这可能吗，我该怎么做?

解决方案

您应该看一下分层数据( http://www.sitepoint.com/hierarchical-data-database/)

<?php

    function tree_view($index)
    {
        $q = mysql_query("SELECT * FROM table_name WHERE SCode=$index");
        if (!mysql_num_rows($q))
            return;
        echo '<ul>';
        while ($arr = mysql_fetch_assoc($q))
        {
            echo '<li>';
            echo $arr['UserID']; //you can add another output there 
            tree_view($arr['RCode']);
            echo '</li>';
        }
        echo '</ul>';
    }

    mysql_connect('localhost', 'root', '');
    $link = mysql_connect('localhost', 'root', '') or die('Could not connect: ' . mysql_error());
    mysql_select_db('test') or die('Could not select database');

    tree_view(11111);

I have a website with a referal system, and I want the users to be able to see what users they referred, using a treeview.

My database table is set up so that when a user refers somebody with his referal code, the new users gets an ID, a sponsor code (the referal code from his "sponser" aka the person who got him into this site) and a referal code (his own referal code to get other people to join under him).

I have no idea how i can get this info out of my MySQL database, and into a treeview script.

I would need to be able to let the user see all the people that he referred, 10 levels deep.

Is this possible and how could I do that?

解决方案

You should give a look at hierarchical data (http://www.sitepoint.com/hierarchical-data-database/)

<?php

    function tree_view($index)
    {
        $q = mysql_query("SELECT * FROM table_name WHERE SCode=$index");
        if (!mysql_num_rows($q))
            return;
        echo '<ul>';
        while ($arr = mysql_fetch_assoc($q))
        {
            echo '<li>';
            echo $arr['UserID']; //you can add another output there 
            tree_view($arr['RCode']);
            echo '</li>';
        }
        echo '</ul>';
    }

    mysql_connect('localhost', 'root', '');
    $link = mysql_connect('localhost', 'root', '') or die('Could not connect: ' . mysql_error());
    mysql_select_db('test') or die('Could not select database');

    tree_view(11111);
