有的客户需要邀请码注册,这就将实现代码贡献出来,在实现邀请码的功能时有参考过一个插件。
思路:
1. 需要新建一个数据表来保存邀请码。
3. 添加邀请码的时候需要能设置前缀,一次生成多个邀请码,邀请码长度可自定义,每个邀请码使用次数可设置。
数据表
code:邀请码、max:邀请码使用次数、users:使用这个验证码的所有用户、status:验证码是否可用。
数据库操作
数据库操作部分代码包括:1. 建立数据库。2.对数据的获取、增加、删除、更改等操作。
- <?php
- //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_invitation_code_install();
- }
- }
- add_action( ‘load-themes.php’, ‘ashuwp_load_theme’ );
- //建立数据表
- function ashuwp_invitation_code_install(){
- global $wpdb;
- $table_name = $wpdb->prefix . ‘invitation_code’;
- if( $wpdb->get_var(“SHOW TABLES LIKE ‘$table_name’”) != $table_name ) :
- $sql = ” CREATE TABLE `”.$wpdb->prefix.“invitation_code` (
- `id` BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
- `code` varchar(40),
- `max` INT NOT NULL,
- `users` varchar(20),
- `status` tinyint
- ) ENGINE = MYISAM DEFAULT CHARSET=utf8;”;
- require_once(ABSPATH . ‘wp-admin/includes/upgrade.php’);
- dbDelta($sql);
- endif;
- }
- //插入数据
- function ashuwp_insert_invitation_code( $code, $max = 1, $users, $status){
- global $wpdb;
- if($code==”){
- return false;
- }
- $code = trim($code);
- $code_exists = ashuwp_check_invitation_code($code);
- if(!$code_exists){
- $insert = “insert into “.$wpdb->prefix.“invitation_code (code,max,users,status) values( ‘$code’, ‘$max’, ”,’1′)”;
- $wpdb->query($insert);
- return true;
- }else{
- return false;
- }
- }
- //检查邀请码是否已存在
- function ashuwp_check_invitation_code( $code ){
- global $wpdb;
- $sql = “select * from “.$wpdb->prefix.“invitation_code where code=’$code’”;
- $result = $wpdb->get_results($sql);
- if(!empty($result)){
- return true;
- }else{
- return false;
- }
- }
- //获取邀请码
- function ashuwp_get_invitation_code($per_page=50, $page=1){
- global $wpdb;
- $page = (int)$page;
- $per_page = (int)$per_page;
- if(!$page){
- $page = 1;
- }
- if(!$per_page){
- $per_page = 50;
- }
- $begin = $per_page*($page-1);
- $end = $per_page*$page;
- $sql = “select * from “.$wpdb->prefix.“invitation_code limit $begin,$end”;
- $results = $wpdb->get_results($sql,’ARRAY_A’);
- return $results;
- }
- //邀请码的删除、启用、禁用。
- function ashuwp_operation_invitation_code( $id, $action ){
- global $wpdb;
- $id = (int)$id;
- if(!$id){
- return false;
- }
- if(!in_array($action,array(‘delete‘,’deactive’,’active’))){
- return false;
- }
- if($action ==’delete‘){
- $sql = “delete from “.$wpdb->prefix .“invitation_code where id=’$id’”;
- }
- if($action ==’deactive’){
- $sql = “update “.$wpdb->prefix .“invitation_code set status=0 where id=’$id’”;
- }
- if($action ==’active’){
- $sql = “update “.$wpdb->prefix .“invitation_code set status=1 where id=’$id’”;
- }
- $result = $wpdb->query($sql);
- if($result){
- return true;
- }else{
- return false;
- }
- }
网站后台
网站后台部分代码包括:1. 邀请码列表页面。2. 邀请码增加页面。

效果展示
1. 增加邀请码
2. 邀请码列表
结束语
上面范例代码,仅做参考使用,可根据实际自行优化,具体如何使用邀请码也请自行斟酌。
