The following code contains a modification I made to the loadArticle function in J1.5.6 from article.php:
(joomla_root)/components/com_content/models/article.php
-->beginning at line 556 (assuming no other hacks)
IMPORTANT: The code modifications below are aimed at users of JACLplus pro because of the the reference to JACL subgroups. ALSO, you must implement SEF urls so that the url redirection can be properly created.
The key to the functionality of this hack is the function JURI::getInstance. Used in conjunction with base64 encoding, I assembled a method for capturing the current url request, encoding it, and returning in the form:
http://www.yoursite.com/Log-in.html?ret ... TERSGOHEREThis creates a redirect to the login page which, most importantly, redirects you to the originally requested page, assuming your login credentials provide suffecient access rights.
Remember, this is just a temporary hack, though it does work quite well.
Code:
/**

{
global $mainframe;

{
return false;
}
// Load the content if it doesn't already exist
if (empty($this->_article))
{
// Get the page/component configuration
$params = &$mainframe->getParams();
// If voting is turned on, get voting data as well for the article
$voting = ContentHelperQuery::buildVotingQuery($params);
// Get the WHERE clause

Ill lose so many new possible users
