DiscuzX! | 二次开发可能用到的东西
我们上一次在很久以前发过一篇Discuz X3.4 一些常用的接口/入口，最近在做称号系统插件又捣鼓了一些，今后的二次开发中可能会用到的东西。
Discuz!发送系统通知方法notification_add()解析
文章来源：Discuz!发送系统通知方法notification_add解析-CSDN博客
方法定义位置：source\function\function_core.php
代码如下：
function notification_add($touid, $type, $note, $notevars = array(), $system = 0) {
return helper_notification::notification_add($touid, $type, $note, $notevars, $system);
}参数说明：
$touid：接收通知的uid，即发给谁；
$type：通知类型，如system为系统通知，这里$type参数稍微复制一点，下面我们把type参数的各种意义罗列出来供大家参考：
| type | 含义 | type | 含义 | type | 含义 |
|---|---|---|---|---|---|
| appId(数字) | 漫游应用 | task | 任务 | clickpic | 图片顶操作 |
| myapp | 应用邀请或请求 | wall | 留言 | doing | 记录 |
| credit | 积分充值 | piccomment | 图片评论 | pmreport | 消息举报 |
| goods | 商品 | blogcomment | 日志评论 | sharenotice | 分享通知 |
| mod_member | 用户审核 | sharecomment | 分享评论 | group | 群组 |
| system | 系统消息 | follow | 关注 | reward | 悬赏 |
| group | 群组审核通过 | pusearticle | 推送 | activity | 活动 |
| report | 举报 | at | @功能 | thread | 主题 |
| verify | 认证 | pcomment | 点评 | blog | 日志 |
| manage_ | 管理通知 | post | 回帖引用 | article | 文章 |
| magic | 道具 | show | 排行榜 | clickarticle | 文章顶操作 |
| poke | 打招呼 | clickblog | 日志顶操作 | friend | 好友 |
$note：通知内容，支持html代码；
$notevars：附加参数，如：actor、from_num、from_id、from_idtype
$system：是否系统通知，默认0，强制转为系统通知；
详细代码逻辑参考helper_notification类代码
helper类所在位置：\source\class\helper\helper_notification.php

原文：Discuz!开发之网站后台表单生成函数showsetting()详情-CSDN博客
Discuz!为了界面统一，专门封装了一个表单生成函数showsetting()，使用改函数几乎可以生成任意web表单，本文就来介绍一下这个函数的用法：
定义文件：\source\function\function_admincp.php

}参数说明：
$setname - 指定输出标题，如:setting_basic_bbname, 自动匹配描述文字为：setting_basic_bbname_comment，comment形式文字可以在./source/language/lang_admincp.php语言包中添加
$varname - 指定表单的name值，如settingnew[bbname]
$value - 指定表单默认值\变量
$type - 表单样式
radio单选
text文本、password密码、number数字
file上传文件
filetext 上传文件或在线文件切换型表单
textarea 多行文本
select 选择框
mradio 高级单选模式
mcheckbox 高级多选模式
binmcheckbox 二进制数值多选模式
mselect 高级选择框模式
color 颜色选择
calendar 日期选择
multiply多表单型，daterange时间范围
其他未在上述样式中出现的$type均独立输出
$disabled - 是否不可修改
$hidden - 是否隐藏
$comment - 强制描述文字
$extra - 表单扩展属性
$setid - 用于拼接表单外层Div的id

//以文本形式输出表单(站点名称 text)：showsetting('setting_basic_bbname', 'settingnew[bbname]', $setting['bbname'], 'text');//以单选形式输出表单(显示授权信息链接 radio)：showsetting('setting_basic_boardlicensed', 'settingnew[boardlicensed]', $setting['boardlicensed'], 'radio');//以多行文本形式输出表单(网站第三方统计代码 textarea)：showsetting('setting_basic_stat', 'settingnew[statcode]', $setting['statcode'], 'textarea');//以高级单选形式输出表单(新用户注册验证 mradio)showsetting('setting_access_register_verify', array('settingnew[regverify]', array( array(0, $lang['none'], array('regverifyext' => 'none')), array(1, $lang['setting_access_register_verify_email'], array('regverifyext' => '')), array(2, $lang['setting_access_register_verify_manual'], array('regverifyext' => '')))), $setting['regverify'], 'mradio');//以高级多选形式输出表单('允许新用户注册 mcheckbox)showsetting('setting_access_register_status', array('settingnew[regstatus]', array( array('open', $lang['setting_access_register_open']), array('invite', $lang['setting_access_register_invite'], 'showinvite'), $_G['setting']['connect']['allow'] ? array('connect', $lang['setting_access_register_connect'], 'showconnect') : array(),)), $regstatus, 'mcheckbox');Discuz!开发之网站后台消息提醒函数cpmsg()

原文：黄聪：Discuz!X/数据库操做方法、DB::table、C::t - 菜鸟学院 (noobyard.com)
| 函数 | 功能 |
|---|---|
| DB::table($tablename) | 获取正确带前缀的表名，转换数据库句柄， |
| DB::delete($tablename, 条件,条数限制) | 删除表中的数据 |
| DB::insert($tablename, 数据(数组),是否返回插入ID,是不是替换式,是否silent) | 插入数据操做 |
| DB::update($tablename, 数据(数组)条件) | 更新操做 |
| DB::fetch(查询后的资源) | 从结果集中取关联数组，注意若是结果中的两个或以上的列具备相同字段名，最后一列将优先。 |
| DB::fetch_first($sql) | 取查询的第一条数据fetch |
| DB::fetch_all($sql) | 查询并fetch |
| DB::result_first($sql) | 查询结果集的第一个字段值 |
| DB::query($sql) | 普通查询 |
| DB::num_rows(查询后的资源) | 得到记录集总条数 |
| DB::_execute(命令,参数) | 执行mysql类的命令 |
| DB::limit(n,n) | 返回限制字串 |
| DB::field(字段名, $pid) | 返回条件，若是为数组则返回 in 条件 |
| DB::order(别名, 方法) | 排序 |
注意：因为 X1.5 里增长了SQL的安全性检测。所以，若是你的SQL语句里包含如下开头的函数 load_file，hex，substring，if，ord，char。 或者包含如下操做 intooutfile，intodumpfile，unionselect，(select')都将被拒绝执行。php
| 替换参数 | 功能 |
|---|---|
| %t | 表名， |
| %s | 字串，若是是数组就序列化 |
| %f | 按 %F 的样式格式化字串 |
| %d | 整数 |
| %i | 不作处理 |
| %n | 若为空即为0，若为数组，就用',' 分割,不然加引号 |
| 函数 | 功能 |
|---|---|
| C::t($tablename')->count() | 获取表全部行数 |
| C::t($tablename')->update(键值,$data) | 更新键值数据 |
| C::t($tablename')->delete(键值) | 删除键值数据 |
| C::t($tablename')->truncate() | 清空表 |
| C::t($tablename')->insert($data, $return_insert_id,$replace) | 插入数据 |
| C::t($tablename')->fetch_all($ids) | fetch 数据，能够是单一键值或者多个键值数组 |
| C::t($tablename')->fetch_all_field() | fetch全部的字段名表 |
| C::t($tablename')->range($start, $limit, $sort) | fetch值域范围 |
| C::t($tablename')->optimize() | 优化表 |
