Joomla 2.5 render com_content component output

问题

is it possible to render Joomla content from external script? For example I have some html string, which I want to pass to com_content component, to make all content plugin and module features available. I think I should use JDocumentRendererComponent class. Code in my external file:

<?php

require_once ('framework.php'); //loading joomla framework

jimport('joomla.document.html.renderer.component');

$contentHtml = '<p>Some content html</p>';

echo JDocumentRendererComponent::render('com_content',array(),$contentHtml);

?>

What I get is error on the last line:

Fatal error: Class 'JDocumentRendererComponent' not found...

What Im doing wrong? Any ideas?

It's because you haven't included the Joomla framework to the external script. Use the below code. This will ensure that the Joomla! environment is loaded correctly

/* Initialize Joomla framework */
define( '_JEXEC', 1 );
define('JPATH_BASE', dirname(__FILE__) );
define( 'DS', DIRECTORY_SEPARATOR );
/* Required Files */
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
/* To use Joomla's Database Class */
require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' );
/**************************************************/
// Your code starts here...
// Remember that the Site application isn't running, so you cannot access $mainframe or any of its methods.
/**************************************************/

JDocumentRendererComponent Class is located in located in /libraries/joomla/document/html/renderer/component.php if you correct load the framework everything should work fine.

I found other solution for my question. The job can be also done by content plugin events (triggers). The piece of code from components/com_content/views/article/view.html.php:

JPluginHelper::importPlugin('content');
$results = $dispatcher->trigger('onContentPrepare', array ('com_content.article', &$item, &$this->params, $offset));

$item->event = new stdClass();
$results = $dispatcher->trigger('onContentAfterTitle', array('com_content.article', &$item, &$this->params, $offset));
$item->event->afterDisplayTitle = trim(implode("\n", $results));

$results = $dispatcher->trigger('onContentBeforeDisplay', array('com_content.article', &$item, &$this->params, $offset));
$item->event->beforeDisplayContent = trim(implode("\n", $results));

$results = $dispatcher->trigger('onContentAfterDisplay', array('com_content.article', &$item, &$this->params, $offset));
$item->event->afterDisplayContent = trim(implode("\n", $results));

So we can actually make an object from our string and pass it to these triggers. As a result we are getting content rendered like an article, with its major functionality.
