I have developed on simple plugin in Joomla 1.6 I stuck at : How to get article title and article url. I am getting no output if tried to print below statement: echo $article->title; echo $article->id; I have written this in php file, not used MVC architecture. Is there any other settings need to do in Joomla admin side ? Please suggest your pointers for extracting article title and article url. Thanks in advance! Pravin h_45h i tried : public function onContentPrepare($context,&$article, &$params, $limitstart) { echo JRequest::getVar('id'); } Still I am not getting the id. Is this right? The
