** 在TITLE 后加网站名字

在 <jdoc:include type="head" />之前加進:

<?php$mydoc =& JFactory::getDocument();

$mytitle = $mydoc->getTitle();
$conf =& JFactory::getConfig();
$sitename = $conf->getValue('config.sitename'); //取得網站名稱
$mydoc->setTitle($mytitle.' - '.$sitename);
?>

** 列表查询

$db->setQuery("SELECT * FROM `jos_users` WHERE `block` =0 AND `gid` =24");

$q_user=$db->loadObjectList();

foreach($q_user as $q_user_list){

echo $q_user_list->name.'<BR>';

}

** 用户注册

$db =& JFactory::getDBO();

$reg_date = date("Y-m-d H:i:s");

$q_i_1=$db->setQuery("INSERT INTO `jos_users` (`id` ,`name` ,`username` ,`email` ,`password` ,`usertype` ,`block` ,`sendEmail` ,`gid` ,`registerDate` ,`lastvisitDate` ,`activation` ,`params`)VALUES (NULL , '".$post['name']."', '".$post['user_name']."', '".$post['email']."', MD5( '".$post['pwd']."' ) , 'Author', '0', '0', '19', '".$reg_date."', '0000-00-00 00:00:00', '', '');");

$f_i_1=$db->query($q_i_1);

$r_i_2_id = $db->insertid($f_i_1);

$q_i_3=$db->setQuery("INSERT INTO `jos_core_acl_aro` ( `id` , `section_value` , `value` , `order_value` , `name` , `hidden` ) VALUES ( NULL , 'users', '".$r_i_2_id."', '0', '".$post['name']."', '0' );");

$f_i_3=$db->query($q_i_3);

$r_i_5_id = $db->insertid($f_i_3);

$q_i_4=$db->setQuery("INSERT INTO `jos_core_acl_groups_aro_map` ( `group_id` , `section_value` , `aro_id` ) VALUES ( '19', '', '".$r_i_5_id."' );");

$f_i_4=$db->query($q_i_4);

** 获取新插入 ID

echo $db->insertid();

** $user = &JFactory::getUser(); $user->get('gid') 等于 jos_core_acl_aro_groups 表中的 id, jos_users 中的gid 即 groups 的IP

** JOOMLA 弹出 BOX

** module 读取 xml 在 module.php , $params->get( 'custom_code' )

** 输出JOOMLA 跟目录路径的常量 JPATH_ROOT JPATH_ADMINISTRATOR

** 库

$app = JFactory::getApplication();

$app->input->getCmd('Itemid', '');

$app = JFactory::getApplication();

$menu = $app->getMenu();

$mytitle = $menu->getActive(); //输出当前页相关属性

$menu->setActive(627); $menu->setActive($_REQUEST['Itemid']); //设置当前Item

$site_name = $app->getCfg('sitename');

** 跳转到登录再跳转
