效果如下:
示例数据库包含三个表,即用户和用户组之间的关系。
用户表Members
表包含成员(用户)数据,如member_id,member_image等。
CREATE TABLE IF NOT EXISTS `members` ( `member_id` int(9) NOT NULL AUTO_INCREMENT, `member_name` varchar(220) NOT NULL, `member_image` text NOT NULL, `dated` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`member_id`) );
用户组Groups
CREATE TABLE IF NOT EXISTS `groups` ( `group_id` int(9) AUTO_INCREMENT, `group_name` varchar(220), `sort` int(9), `date` timestamp DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`group_id`), KEY `sort` (`sort`) );
用户组之间的关系User_group
用户和用户租表的关系表user_group包含user_id(memeber_id一样),group_id,member_id()和sort(排序)字段。
CREATE TABLE IF NOT EXISTS `user_group` ( `id` int(9) NOT NULL AUTO_INCREMENT, `user_id` int(9) NOT NULL, `group_id` int(9) NOT NULL, `member_id` int(9) NOT NULL, `sort` int(9) NOT NULL, PRIMARY KEY (`id`) );
Javascript脚本
我们对两个类属性:.members和.group运用拖拽。
groups.php
我们在这里处理拖拽添加用户组的数据处理功能。
<?php require_once("multipleDiv.inc.php"); // Initiate Object $obj = new Multiplediv(); // Add or Update Ajax Call if(isset($_GET['m_id']) and isset($_GET['g_id'])) { $obj->addMembers((int)$_GET['m_id'], (int)$_GET['g_id']); exit; } // Remove Memebers from groups Ajax call if(isset($_GET['do'])) { $obj->removeMember($_GET['mid']); exit; } // Reload groups each ajax call if(isset($_GET['reload'])){ echo $obj->getMembers_reload(); exit; } if(isset($_GET['reload_groups'])){ echo $obj->getmembergroups_reload(); exit; } // Initiate Groups and members $members = $obj->public_members(); $groups = $obj->groups(); ?> Friends <?php if(!isset($members)) $members = $obj->public_members(); if($members) { foreach($members as $member) { extract($member); echo "\n"; echo "\n"; echo "".ucwords($member_name)."\n"; echo ""; } } else echo "Members not available"; ?> Groups <?php if(!isset($groups)) $groups = $obj->groups(); if($groups) { foreach($groups as $group) { extract($group); echo "\n"; echo ucwords($group_name); echo ""; echo ""; echo "
multipleDiv.inc.php
在这里修改数据库连接信息。
<?php // Database declaration's define("SERVER", "localhost"); define("USER", "username"); define("PASSWORD", "password"); define("DB", "database"); class Multiplediv { ........................ ........................ ......................... } ?>
到这里,我们关于如何实现Google plus 的好友拖拽分组功能就完成了。以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
