去年主题君开发了一款站长社区的WordPress主题，主题君用纯代码做了WordPres用户积分系统，答应过宁总要把教程写出来的，今天算是有时间整理了。
首先声明：核心代码搬运了ashuwp的教程，然后主题君自己集成了一些自己的代码，代码比较复杂，没有一定基础的朋友不要轻易尝试。
整理思路：
1. 需要准备两个数据表。
(1) 积分动态表，用来记录所有用户的积分增减情况。
(2) 用户积分总表，用来记录用户的积分总量，当然用户积分总数可以记录到usermeta数据表中，所以这个表不是必须的。
2. 后台需要3个页面。
(1) 积分动态，从“积分动态表”中获取数据，展示用户积分动态。
(2) 用户积分，从“用户积分表”中获取数据，方便查看用户的积分总量。
(3) 积分增减页面，用于给用户增减积分。
下面教程开始吧：
一、新建数据表。
1. 积分动态表points_activity中的字段有id，用户id，积分(异动数)，描述，余额，时间。
2. 用户积分表points中的字段就两个：用户id，积分数。
//在第一次启用主题时执行。
function ashuwp_load_theme() {
global $pagenow;
if ( is_admin() && 'themes.php' == $pagenow && isset( $_GET['activated'] ) ){
ashuwp_points_install();
}
}
add_action( 'load-themes.php', 'ashuwp_load_theme' );
//新建数据表points_activity和points
function ashuwp_points_install(){
global $wpdb;
$table_name = $wpdb->prefix . 'points_activity'; //积分动态表
$table_name2 = $wpdb->prefix . 'points'; //积分汇总表
$charset_collate = $wpdb->get_charset_collate();
if( $wpdb->get_var("SHOW TABLES LIKE '$table_name'") != $table_name ) :
$sql = " CREATE TABLE `".$table_name."` (
`id` BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`user_id` BIGINT(40),
`points` INT NOT NULL,
`description` longtext,
`balance` INT NOT NULL,
`date` DATETIME NOT NULL
) $charset_collate;";
require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
dbDelta($sql);
endif;
if( $wpdb->get_var("SHOW TABLES LIKE '$table_name2'") != $table_name2 ) :
$sql2 = " CREATE TABLE `".$table_name2."` (
`user_id` BIGINT(40) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`points` INT NOT NULL
) $charset_collate;";
dbDelta($sql2);
endif;
}二、数据库操作函数
//根据用户id获取某个用户的积分数
function ashuwp_get_user_points($user_id){
global $wpdb;
$user = get_user_by('ID', $user_id);
if(!$user){
return 0;
}
$points_table = $wpdb->prefix . 'points';
$sql = "select points from ".$points_table." where user_id={$user_id}";
$result = $wpdb->get_var($sql);
if(!$result){
return 0;
}else{
return $result;
}
}
//更新(新增)用户积分.
function ashuwp_update_user_points($user_id, $new_points){
global $wpdb;
$user = get_user_by('ID', $user_id);
if(!$user){
$msg = array(
'state' => 'error',
'msg' => 'User Error',
);
return $msg;
}
if( !is_numeric($new_points)|| $new_points<0){
$msg = array(
'state' => 'error',
'msg' => 'Points not number or points error',
);
return $msg;
}
$points_table = $wpdb->prefix . 'points';
$points_exist = $wpdb->get_var( "select count(*) from {$points_table} where user_id='{$user_id}'" );
if($points_exist){
$sql = "update {$points_table} set points='{$new_points}' where user_id='{$user_id}'";
}else{
$sql = "insert into {$points_table} ( user_id, points ) values( '{$user_id}', '{$new_points}' )";;
}
$result = $wpdb->query($sql);
if($result){
$msg = array(
'state' => 'succeed',
'msg' => 'Points Updated.',
);
return $msg;
}else{
$msg = array(
'state' => 'error',
'msg' => 'Points update failed.',
);
return $msg;
}
}
//从用户积分表获取数据，后台积分汇总页面需要获取数据。
function ashuwp_get_points( $args=array() ){
global $wpdb;
$defaults = array(
'per_page' => '50',
'paged' => '1',
);
$args = wp_parse_args( $args, $defaults );
$page = (int)$args['paged'];
$per_page = (int)$args['per_page'];
if(!$page){
$page = 1;
}
if(!$per_page){
$per_page = 50;
}
$begin = $per_page*($page-1);
$end = $per_page*$page;
$points_table = $wpdb->prefix . 'points';
$sql = "select * from $points_table order by user_id asc limit $begin,$end";
$results = $wpdb->get_results($sql,'ARRAY_A');
return $results;
}
//统计数据条数，后台积分汇总页面需要获取数据。
function ashuwp_count_points(){
global $wpdb;
$points_table = $wpdb->prefix . 'points';
$sql = "select count(*) from $points_table";
$results = $wpdb->get_var($sql);
return $results;
}然后是对积分动态表的操作仅需要增加即可，不需要删除。
/*增加入一条积分动态*/
function ashuwp_add_points_activity( $args=array() ){
global $wpdb;
$defaults = array(
'user_id' => '',
'action' => '',
'points' => '',

$args = wp_parse_args( $args, $defaults );
//判断用户id是否合法

if(!$user){
$msg = array(
'state' => 'error',
'msg' => 'User Error',
);
return $msg;
}
//仅增加和减少两种操作。
if( !in_array( $args['action'], array( 'add', 'reduce' ) )){
$msg = array(
'state' => 'error',
'msg' => 'Operate Error',
);
return $msg;
}
//检测积分异动数是否合法
if( !is_int($args['points']) ){
$msg = array(
'state' => 'error',
'msg' => 'Points Error',
);
return $msg;
}
//处理描述
$args['description'] = sanitize_text_field($args['description']);
//处理异动数，和计算余额
$old_points = (int)ashuwp_get_user_points($args['user_id']);
if($args['action']=='add'){
$balance = $old_points+$args['points'];
$change = $args['points'];
if($balance!=$old_points){
//将新余额更新到用户积分表。
$update = ashuwp_update_user_points($args['user_id'],$balance);
}
}
if($args['action']=='reduce'){
$balance = $old_points-$args['points'];
$change = -$args['points']; //若是减少，数据库中保存为负数。
if($balance!=$old_points){
$update = ashuwp_update_user_points($args['user_id'],$balance);
}
}
if( ($balance!=$old_points) && $update['state'] != 'succeed' ){
$msg = array(
'state' => 'error',
'msg' => $update['msg'],
);
return $msg;
}
$table_name = $wpdb->prefix . 'points_activity';
//插入数据
$args['date'] = date( "Y-m-d H:i:s", time());
$sql = "insert into $table_name ( user_id, points, description, balance, date ) values( '{$args['user_id']}', '{$change}', '{$args['description']}', '{$balance}', '{$args['date']}' )";
$result = $wpdb->query($sql);
if($result){
$msg = array(
'state' => 'succeed',
'msg' => 'succeed!',
);
return $msg;
}else{
//若动态插入失败，将用户积分表回滚。
ashuwp_update_user_points($args['user_id'],$old_points);
$msg = array(
'state' => 'error',
'msg' => 'Insert Error',
);
return $msg;
}
}
/*从积分动态表中获取数据，后台页面中需要。
* 需支持条件查询方便后台管理。
*/
function ashuwp_get_points_activity( $args=array() ){
global $wpdb;
$defaults = array(
'user_id' => '',
'per_page' => '50',
'paged' => '1',
'action' => ''
);
$args = wp_parse_args( $args, $defaults );
//处理页码
$page = (int)$args['paged'];
$per_page = (int)$args['per_page'];
if(!$page){
$page = 1;
}
if(!$per_page){
$per_page = 50;
}
$begin = $per_page*($page-1);
$end = $per_page*$page;
$table_name = $wpdb->prefix . 'points_activity';
$sql = "select * from $table_name where 1=1 ";
//查询用户id
if($args['user_id']!=''){
$user_id = (int)$args['user_id'];

$sql .= "order by id desc limit $begin,$end";
$results = $wpdb->get_results($sql,'ARRAY_A');
return $results;
}
/*统计积分动态的记录数
* 加入统计条件方便后台管理
*/
function ashuwp_count_points_activity( $args=array() ){
global $wpdb;
$defaults = array(
'user_id' => '',
'action' => ''
);
$args = wp_parse_args( $args, $defaults );

return $results;
}三、新建后台积分页面
1. 积分动态页面。
后台页面设计到class-wp-list-table类的应用，就不一一加注释了。
if(!class_exists('WP_List_Table')) {

return $return_datas;

ashuwp_user_points_admin::get_instance();在遇到某个操作比如：充值成功、购买成功、发表评论，执行ashuwp_add_points_activity函数即可。
范例一：充值成功增加积分。
//准备参数
$user_id = 1; //用户id
$points = 10; //积分数
$desc = '充值:'.$points;
$args = array(
'user_id' => $user_id,
'action' => 'add', //增加
'points' => $points,
'description' => $desc,
);
$chognzhi = ashuwp_add_points_activity($args);五、结语
本教程的思路、代码仅供参考，代码为阿树从实际项目中剥离而来，在代码处理过程中，不敢保证不出错，特别是如果遇到有两个连续的empty请自行删除一个。
