Discuz!論壇如何發送系統通知呢，怎么樣讓用戶收到系統發送的通知呢？Discuz!發送系統通知方法notification_add解析，想要知道Discuz!論壇怎么樣發送通知就來看看吧

方法定義位置：

source/function/function_core.php

代碼如下：

view plaincopy

functionnotification_add($touid, $type, $note, $notevars= array(), $system= 0) { returnhelper_notification::notification_add($touid, $type, $note, $notevars, $system);  

}  

參數說明：

$touid：接收通知的uid，即發給誰；

$type：通知類型，如system為系統通知，這里$type參數稍微復制一點，下面我們把type參數的各種意義羅列出來供大家參考：

$note：通知內容，支持html代碼；

$notevars：附加參數，如：actor、from_num、from_id、from_idtype

$system：是否系統通知，默認0，強制轉為系統通知；

詳細代碼邏輯參考helper_notification類代碼

helper類所在位置：

/source/class/helper/helper_notification.php
