wordpress用户积分的实现代码

WordPress教程 3827

对于开放了会员注册的wordpress网站而言，用户积分是提升会员活跃度的一个重要元素，给wordpress增添用户积分功能可以通过myCRED、CubePoints等wordpress积分插件实现，同时也可以通过主题集成相关代码的方式实现，下面是阿树工作室分享的wordpress用户积分实现代码。

实现思路

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。
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。

操作步骤

新建数据表

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。

用户积分表points中的字段就两个：用户id，积分数。

在主题functions.php文件添加以下代码：

    //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;
    }
数据库操作函数

1、先是对用户积分表points的操作，用户积分所需要的操作仅需要更新、获取两个操作。

    //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){

        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;
    }

2、然后是对积分动态表的操作仅需要增加即可，不需要删除。

建立后台页面

1、积分动态页面。

后台页面设计到class-wp-list-table类的应用。

    //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);
