Hi all,

(Reposted as previous was posted in wrong category)

I have generated a component for testing with Cook and am now migrating it to work on Joomla 3.0. Back-end went fairly smoothly, but seem to have an issue with SEF and the front-end when I am accessing the component via a menu (or any SEF link really).

So for example when I do this:
www.mydomain.com/index.php?option=my_component&view=myview

It works fine.

But this:
www.mydomain.com/componentname/myview

results in a infinite redirect loop.

I have been checking the router.php generated by Cook and it seems to endlessly call the buildRoute.

This is the code of the router.php:
/**
 * Build the route for the com_wpf component
 *
 * @param	array	An array of URL arguments
 *
 * @return	array	The URL arguments to use to assemble the subsequent URL.
 */
function WpfBuildRoute(&$query) {

    logThis("Building Route\n");
    logThis("Query:\n");
    foreach ($query as $field=>$value) {
        logThis($field.'=>'.$value."\n");
    }
    logThis("\n");

    $segments = array();
    if (isset($query['view'])) {
        logThis("We have a view {$query['view']}\n");
        $view = $query['view'];
        $segments[] = $view;
        unset($query['view']);
    }

    if (isset($query['layout'])) {
        logThis("We have a layout {$query['layout']}\n");
        $segments[] = $query['layout'];
        unset($query['layout']);
    }


    if (isset($query['id'])) {
        if (in_array($view, array('country', 'editcountry', 'projectstatus', 'editprojectstatus', 'projecttype', 'editprojecttype', 'service', 'editservice', 'sector', 'editsector', 'client', 'editclient', 'clientsector', 'editclientsector', 'project', 'editproject', 'screenshot', 'editscreenshot', 'serviceapplied', 'editserviceapplied'))) {
            $segments[] = (is_array($query['id']) ? implode(',', $query['id']) : $query['id']);
            unset($query['id']);
        }
    };

    logThis("Segments:\n");
    foreach ($segments as $field=>$value) {
        logThis($field.'=>'.$value."\n");
    }
    logThis("\n\n");
    return $segments;
}

/**
 * Parse the segments of a URL.
 *
 * @param	array	The segments of the URL to parse.
 *
 * @return	array	The URL attributes to be used by the application.
 */
function WpfParseRoute($segments) {
    logThis("Parsing route\n");
    logThis("Segments:\n");
    foreach ($segments as $field=>$value) {
        logThis($field.'=>'.$value."\n");
    }
    logThis("\n\n");
    $vars = array();


    $vars['view'] = $segments[0];

    $nextPos = 1;
    if (isset($segments[$nextPos])) {
        $vars['layout'] = $segments[$nextPos];
        $nextPos++;
    }

    //Item layout : get the cid value
    if (in_array($vars['view'], array('country', 'editcountry', 'projectstatus', 'editprojectstatus', 'projecttype', 'editprojecttype', 'service', 'editservice', 'sector', 'editsector', 'client', 'editclient', 'clientsector', 'editclientsector', 'project', 'editproject', 'screenshot', 'editscreenshot', 'serviceapplied', 'editserviceapplied')) && isset($segments[$nextPos])) {
        $slug = $segments[$nextPos];
        $id = explode(':', $slug);
        $vars['id'] = (int) $id[0];

        $nextPos++;
    }
    logThis("Vars:\n");
    foreach ($vars as $field=>$value) {
        logThis($field.'=>'.$value."\n");
    }
    logThis("\n\n");

    return $vars;
}

Does anybody else had this problem and/or know how to fix it?

Many thanks,

Misha

Little update:

I managed to "fix" it. Not sure if this is the right solution and would love to hear so if it isn't.

I noticed in the main controller of the component there is something built-in for when the page is called via a post. This checks the $_GET variable. If I change that to check the JRequest, the problem disappears.

So the display function in my general controller is now:
	public function display($cachable = false, $urlparams = false)
	{
		$jinput = new JInput;


		parent::display();

		//If page is called through POST only, reconstruct the url
                // MOD: change this to check the JRequest to avoid problems with SEF and infinite redirect loop
                if (!JRequest::getVar('option'))
                //if (!isset($_GET['option']))
		{
			//Kill the post and rebuild the url
			$this->setRedirect(WpfHelper::urlRequest());
			return;
		}

		return $this;
	}

Any comments or feedback are welcome.

Kind regards,

Misha

Hi Misha,

Your fix looks good to me!

The $_GET in the controller has probably been hanging around there since Cook version 1 I guess!

Karma++

I'll post this to admin to ensure that the old code is updated!

Thanks,

Gez

By the way, it may be worth checking the parent controller in your classes folder too, just in case there are any other $_GET references.

Hi Gez,

Just checked. In the parent controller there are no references to that. Just in the main controller generated in the root of the component (both admin and front-end of course).

Cheers,

Misha
