織夢dedeCMS系統(tǒng)整合discuz論壇后會員注冊后不用激活

時間： 2018-11-29 09:42 閱讀：次作者：素材無憂網(wǎng)

下面說下dedecms整合discuz后會員注冊后不用激活的實現(xiàn)，以前做站時，一直在想，dede和dz整合后，會員在網(wǎng)站注冊后到論壇能不能不再激活，看著可不舒服，現(xiàn)在總算解決了，閑話不說了，下面進入正題，百度也不讓發(fā)附件，只有啰嗦點了，呵呵，比較長，分3篇：
1.首先找到dede－〉api－〉uc.php文件
打開uc.php,將內(nèi)容替換為：
<?php
/**************************二次開發(fā)說明**************************************
此模塊應(yīng)用于DEDECMS5.7版本，請?zhí)鎿QAPI文件夾的UC.PHP，替換后，通過DEDE注冊的用戶，
訪問論壇系統(tǒng)可以免激活，實現(xiàn)同時登陸同時退出。
