今天记录3c之家 兰州短租公寓建设过程中遇到的一点小问题。由于网站需要，找了个会员积分系统来用用，AlphaUserPoints，总体感觉很是不错，先来看看后台
还可以吧？功能很是强大。
于是，我新建了一个菜单->会员中心，指向了AlphaUserPoints的个人页面，然而在前台点击后问题出现了，错误提示：您没有权限观看此页面；是啊，没有登录。可是想想这样的话会员肯定会不高兴的，最起码让网页直接能跳转到登录页面呢。好，开始分析源代码，下面是此组件的文件列表
我们来看看控制器，
class alphauserpointsController extends JController
{
function display() {
parent::display();
}
}
里面没有东西，进controllers文件夹看看：

有这几个文件，分析url：http://3c-home.com/index.php?option=com_alphauserpoints&view=account&Itemid=103
可知此应该使用的是account视图，对于的也就是account控制器，打开文件查看display函数部分
function display ()
{
$app = JFactory::getApplication();
require_once (JPATH_ROOT.DS.'components'.DS.'com_alphauserpoints'.DS.'helper.php');
$com_params = JComponentHelper::getParams( 'com_alphauserpoints' );
$model = &$this->getModel ( 'alphauserpoints' );
$view = $this->getView ( 'account','html' );
// current user
$user = JFactory::getUser();
// profil request
$userid = JRequest::getVar( 'userid', '', 'default', 'string' );
if ( !$user->id && !$com_params->get( 'allowGuestUserViewProfil', 1 ) ) {
$msg = JText::_('ALERTNOTAUTH' );
$app->redirect('index.php', $msg);
} 这段代码就是检测是否有用户登录，如果没有用户登录就跳转到首页，并显示错误消息$msg.
// check referre ID
if ( ! $userid ) {
$referrerid = $model->_checkUser();
} else {
$referrerid = $userid;
}
// Rule Profile View
if ( $referrerid != @$_SESSION['referrerid'] )
{
$keyreference = AlphaUserPointsHelper::buildKeyreference( 'sysplgaup_profile_view', $user->id );
$username = ( $user->username ) ? $user->username : JText::_('AUP_GUEST');
$datareference = JText::_('AUP_PROFILE_VIEW_REFERENCE') . ' ' . $username;
AlphaUserPointsHelper::userpoints ( 'sysplgaup_profile_view' , $referrerid, 0, $keyreference, $datareference );
}
// End rule Profile View
// Get the parameters of the active menu item
$params = $model->_getParamsAUP();
$num_item_activities = $params->get( 'num_item_activities', 10 );
$_get_last_points = $model->_get_last_points ( $referrerid, $num_item_activities );
$_listing_last_points = $_get_last_points[0];
$_listing_total = $_get_last_points[1];
$_listing_limit = $_get_last_points[2];
$_listing_limitstart = $_get_last_points[3];
$rowsreferrees = $model->_get_referrees ( $referrerid );
$pointsearned = $model->_pointsearned(); // users points earned TOP 10
$totalpoints = $model->_totalpoints(); // entire community
$mypointsearned = $model->_mypointsearned($referrerid);
$mypointsspent = $model->_mypointsspent($referrerid);
$mypointsearnedthismonth= $model->_mypointsearnedthismonth($referrerid);
$mypointsspentthismonth = $model->_mypointsspentthismonth($referrerid);
$mypointsearnedthisday = $model->_mypointsearnedthisday($referrerid);
$mypointsspentthisday = $model->_mypointsspentthisday($referrerid);
$_average_age = _get_average_age_community();
$_user_info = AlphaUserPointsHelper::getUserInfo ( $referrerid );
$currenttotalpoints = $_user_info->points;
$lastupdate = $_user_info->last_update;
$referraluser = $_user_info->referraluser;
$myname = $_user_info->name;
$myusername = $_user_info->username;
$mybirthday = $_user_info->birthdate;
$referralname = "";
if ( $referraluser ) {
$referralinfo = AlphaUserPointsHelper::getUserInfo ( $referraluser );
$referralname = $referralinfo->username;
}
// get level/rank if exist
$userrankinfo = AlphaUserPointsHelper::getUserRank ( $referrerid );
// get medals if exist
$medalslistuser = AlphaUserPointsHelper::getUserMedals ( $referrerid );
// load avatar
$useAvatarFrom = $com_params->get('useAvatarFrom');
$height = 100;
if ( $useAvatarFrom=='alphauserpoints' ) JPlugin::loadLanguage( 'com_media', JPATH_ADMINISTRATOR );
$avatar = getAvatar( $useAvatarFrom, $_user_info, $height );
// Get coupons code
$resultCoupons = $model->_getMyCouponCode( $referrerid );
$view->assign('params', $params );
$view->assign('cparams', $com_params );
$view->assign('referreid', $referrerid );
$view->assign('currenttotalpoints', $currenttotalpoints );
$view->assign('rowslastpoints', $_listing_last_points );
$view->assign('total', $_listing_total );
$view->assign('limit', $_listing_limit );
$view->assign('limitstart', $_listing_limitstart );
$view->assign('lastupdate', $lastupdate );
$view->assign('referraluser', $referraluser );
$view->assign('referralname', $referralname );
$view->assign('rowsreferrees', $rowsreferrees );
$view->assign('userid', $user->id);
$view->assign('userrankinfo', $userrankinfo);
$view->assign('medalslistuser', $medalslistuser);
$view->assign('pointsearned', $pointsearned);
$view->assign('totalpoints', $totalpoints);
$view->assign('mypointsearned', $mypointsearned);
$view->assign('mypointsspent', $mypointsspent);
$view->assign('mypointsearnedthismonth', $mypointsearnedthismonth);
$view->assign('mypointsspentthismonth', $mypointsspentthismonth);
$view->assign('mypointsearnedthisday', $mypointsearnedthisday);
$view->assign('mypointsspentthisday', $mypointsspentthisday);
$view->assign('myname', $myname);
$view->assign('myusername', $myusername);
$view->assign('avatar', $avatar);
$view->assign('birthday', $mybirthday);
$view->assign('user_info', $_user_info);
$view->assign('useAvatarFrom', $useAvatarFrom);
$view->assign('mycouponscode', $resultCoupons);
$view->assign('userinfo', $_user_info);
$view->assign('average_age', $_average_age);
// Display
$view->_display();
}
现在找到了地方，我们来做修改，把下面代码的跳转改改：
if ( !$user->id && !$com_params->get( 'allowGuestUserViewProfil', 1 ) )
{$msg = JText::_('ALERTNOTAUTH' );
//login first
$app->redirect('index.php?option=com_users&view=login', $msg);}
现在把跳转改到了登录表单，然后把ALERTNOTAUTH对于的汉语提示改改，改成友善一点，就是提示顾客登录。继续测试，成功，窃喜呢。
点登录。。。。。
不对啊，登录以后是系统自带的用户界面啊，我得定向到新的会员界面啊，怎么办呢，我想还是把系统自带的user组件改改吧
找到com_user文件夹，好多文件啊，慢慢看吧，先入手控制器，
com_user下的controller.php文件里面没有点击login按钮触发的事件，最终在controllers文件夹下的user.php文件中找到相关代码。就是login函数
public function login()
{
JSession::checkToken('post') or jexit(JText::_('JInvalid_Token'));
$app = JFactory::getApplication();
// Populate the data array:
$data = array();
$data['return'] = base64_decode(JRequest::getVar('return', '', 'POST', 'BASE64'));
$data['username'] = JRequest::getVar('username', '', 'method', 'username');
$data['password'] = JRequest::getString('password', '', 'post', JREQUEST_ALLOWRAW);
// Set the return URL if empty.
if (empty($data['return'])) {
$data['return'] = 'index.php?option=com_users&view=profile';
}
// Set the return URL in the user state to allow modification by plugins
$app->setUserState('users.login.form.return', $data['return']);
// Get the log in options.
$options = array();
$options['remember'] = JRequest::getBool('remember', false);
$options['return'] = $data['return'];
// Get the log in credentials.
$credentials = array();
$credentials['username'] = $data['username'];
$credentials['password'] = $data['password'];
// Perform the log in.
if (true === $app->login($credentials, $options)) {
// Success
$app->setUserState('users.login.form.data', array());
$app->redirect(JRoute::_($app->getUserState('users.login.form.return'), false));
} else {
// Login failed !
$data['remember'] = (int)$options['remember'];
$app->setUserState('users.login.form.data', $data);
$app->redirect(JRoute::_('index.php?option=com_users&view=login', false));
}
}
红色的那几行就是成功登陆后的跳转的相关代码，我直接跳转到我们需要的页面看看：
if (empty($data['return'])) {
// $data['return'] = 'index.php?option=com_users&view=profile';
$data['return'] ='index.php?option=com_alphauserpoints&view=account&Itemid=103';
}
成功了。
总结：本次修改代码是在对组件开发不是特别熟悉的前提下进行的，在修改代码时考虑的不是很完备，如果能在AlphaUserPoints组件中实现登陆及相关的跳转就再好不过了，但时间紧迫，目前先将就使用。也希望通过这次的修改，为下次自己写组件奠定一些基础。
