Joomla模块学习之后台mod_logged模块
在线用户模块
后台管理模块效果图
原理:
后台mod_logged模块通过在后台配置相应的信息. 返回在线用户列表
配置界面:
mod_feed模块结构图:
关键代码
(mod_logged.php代码) jimport('joomla.html.pagination'); $db =& JFactory::getDBO(); $user =& JFactory::getUser(); // TODO - pagination needs to be completed in module $limit = $mainframe->getUserStateFromRequest('limit', 'limit', $mainframe->getCfg('list_limit'), 'int'); $limitstart = $mainframe->getUserStateFromRequest('mod_logged.limitstart', 'limitstart', 0, 'int'); // hides Administrator or Super Administrator from list depending on usertype // 根据用户类型隐藏管理员和超级管理员 $and = ''; // administrator check // 如果用户属于管理员组,隐藏超级管理员组用户在线信息 if ( $user->get('gid') == 24 ) { $and = ' AND gid != "25"'; } // manager check // 如果用户属于经理组,隐藏管理员组和超级管理员组用户在线信息 if ( $user->get('gid') == 23 ) { $and = ' AND gid != "25"'; $and .= ' AND gid != "24"'; } // get the total number of records $query = 'SELECT COUNT(*)' . ' FROM #__session' . ' WHERE userid != 0' . $and . ' ORDER BY usertype, username' ; $db->setQuery( $query ); $total = $db->loadResult(); // page navigation $pageNav = new JPagination( $total, $limitstart, $limit ); $query = 'SELECT username, time, userid, usertype, client_id' . ' FROM #__session' . ' WHERE userid != 0' . $and . ' ORDER BY usertype, username' ; $db->setQuery( $query ); $rows = $db->loadObjectList(); require( dirname( __FILE__ ).DS.'tmpl'.DS.'default.php' );
(mod_logged default.php代码) <?php $i = 0; $now = time(); foreach ($rows as $row) : $auth = $user->authorize( 'com_users', 'manage' ); if ($auth) : $link = 'index.php?option=com_users&task=edit&cid[]='. $row->userid; $name = '<a href="'. $link .'" mce_href="'. $link .'" title="'.
