Joomla 2.5 SEF and JRequest

Question

(Migrated this question from Stack Overflow)

I am working on a client's website which is based on the Joomla 2.5 framework. With SEF turned off (the in built Joomla version) the URL is this

http://(domain)/index.php?option=com_cmgroupbuying&view=alldeals&Itemid=424

The user has a plugin, I have built into a plugin the line to make sure this plugin only fires when the component CMGroupbuying is in use

$component = JRequest::getCmd('option'); 
if($component =='com_cmgroupbuying')
               { etc etc }

With SEF turned off, this works beautifully. However when I enable SEF the URL turns into

http://(domain)/the-deals

and the detection script stops working as joomla just no longer sees the Request::getCmd('option'); being equal to com_cmgroupbuying which to be honest, blows me away as it renders getCmd totally useless. I have seen other prople suffer with this in the part but not found any definitive fix

Can anyone offer a solution to stop this failure of Joomla, either by some extra lines in the DEFAULT htaccess fault to retain this information for joomla to use.

An alternative solution, though I have not found anything that does this, is to limit the plugin to only certain menu items like you can do with a module.

EDIT

This is the full code of the plugin. I have not included the helper as this is just a mass list of all agents for lookups.

jimport('joomla.plugin.plugin');

require_once 'helper.php';

class plgSystemCMMobileDetection extends JPlugin {
    public function onAfterInitialise()
    {
        if(JPATH_BASE != JPATH_ADMINISTRATOR)
        {
            $browser        = new Mobile_Detect();
            $mobileCookie   = JFactory::getApplication()->input->cookie->get('cmmobileRequestDesktop',
-1, 'int');
            $component      = JRequest::getVar('option');

            if(($browser->isMobile() || $browser->isTablet()) && ($mobileCookie == 0 || $mobileCookie == -1) && $component == 'com_cmgroupbuying')
            {
                $configuration  = $this->getConfiguration();
                $db             = JFactory::getDBO();
                $query          = "SELECT params FROM #__template_styles WHERE client_id = 0 AND template = ".$db->Quote($configuration['mobile_template'])." ORDER BY id LIMIT 1";
                $db->setQuery($query);
                $params         = $db->loadResult();

                if(empty($params))
                    $params = '{}';

                JFactory::getApplication()->setTemplate($configuration['mobile_template'], $params);
            }
        }
    }

    public function getConfiguration()
    {
        $db             = JFactory::getDBO();
        $query          = 'SELECT * FROM #__cmgroupbuying_configuration WHERE id = 1';
        $db->setQuery($query);
        $configuration  = $db->loadAssoc();

        if($db->getErrorNum())
        {
            //JError::raiseError(500, implode('<br />', $errors));
            return false;
        }

        return $configuration;
    } } ?>

This does include my alteration, which basically has one function, stop the plugin loading on ANY page that is NOT using option=com_cmgroupbuying as it interferes with the mobile template of all the other pages. As already stated, this works beautifully when SEF is turned off.

Answer 1

May I ask you what plugin event you are using? Because your code should work fine after the routing is done.

During the routing, Joomla parses the URL and maps them internally back to a non SEF URL. Which will get you the option, Itemid and that stuff.
