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：

$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

相关代码：

    public static function notification_add($touid, $type, $note, $notevars = array(), $system = 0, $category = -1) {

Discuz!开发之网站后台表单生成函数showsetting()

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

函数定义：

}

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

使用方法举例：

//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');
