问题 I currently have 2 'layouts' for articles in my Joomla 2.5 install default.php default_links.php feature_link.php feature_link.php which work as intended when each is selected in the 'Edit Article' screen of the 'Article Manager' under 'Alternative Layouts'.

问题 I'm starting off with both php and Joomla development, and finding it difficult working within Joomla to do some fairly simple stuff. Went through the Joomla MVC example and Lynda (and have built a few simple views so far). I have a helper file/class/function that outputs all the userids that exist in the "completed" table so I can display a link for either a new record based on that user or edit an existing user's record.

问题 how do I only show content in a single article? I am using Joomla 2.5 and Ajax to call a single article, but when I render the article in a <div> tag, I render again the header, the footer and all the page , but I only want the content.
