JRoute does not show the URL it is supposed to

Question

I have the following problem:

I set a URL with JRoute like this:

 JRoute::_('index.php?option=com_gallery&view=gallery');

This gives me example.site/gallery, which is correct, however, if I want to display this same link, in a different view - example - view finishing, it does not show this same link, but it shows the link of the view "finishing" instead.

So, in short, if I'm displaying this JRoute::_('index.php?option=com_gallery&view=gallery') in the view "finishing", instead of displaying example.site/gallery, it displays example.site/finishing

Actually it happens with any link; if I do this: echo JRoute::_('index.php') it gives me example.site/finishing

UPDATE:

My Router File:

<?php


defined('_JEXEC') or die;

class GalleryRouter implements JComponentRouterInterface
{

    public function build(&$query)
    {
        $segments = array();
        if (isset($query['id']))
        {
            $db = JFactory::getDbo();
            $qry = $db->getQuery(true);
            $qry->select('alias');
            $qry->from('#__gallery_images');
            $qry->where('id = ' . $db->quote($query['id']));
            $db->setQuery($qry);
            $alias = $db->loadResult();
            $segments[] = $alias;
            unset($query['id']);
        }
        unset($query['view']);
        return $segments;
    }

    public function parse(&$segments)
    {
        $vars = array();

        $db = JFactory::getDbo();
        $qry = $db->getQuery(true);
        $qry->select('id');
        $qry->from('#__gallery_images');
        $qry->where('alias = ' . $db->quote($segments[0]));
        $db->setQuery($qry);
        $id = $db->loadResult();

        if(!empty($id))
        {
            $vars['id'] = $id;
            $vars['view'] = 'gallery';

        }

        return $vars;
    }

    public function preprocess($query)
    {
        return $query;
    }
}

Hidden menu links:

index.php?option=com_gallery&view=gallery which gives me: example.site/gallery

index.php?option=com_gallery&view=finising which gives me example.site/finishing

If I do an echo JRoute::_('index.php?option=com_gallery&view=gallery') in the view "finishing", instead of giving me example.site/gallery it displays example.site/finishing.

I'm not sure how JRoute works but as far as I know, it should display example.site/gallery regardless of the view it is being dispayed on, but pelase, correct if I am wrong.

You can use your custom router code to find a menuitem which matches the view you enter in your JRoute::_() call, and I think it's easiest to do this in the preprocess method.

Add this code into your router.php preprocess method:

if (isset($query['view'], $query['Itemid']))
{
    $sitemenu = JFactory::getApplication()->getMenu();
    $targetView = $query['view'];
    $currentMenuitem = $sitemenu->getItem($query['Itemid']);
    if (strpos($currentMenuitem->link, "view=$targetView") === FALSE)  // if view doesn't match
    {
        $galleryMenuitems = $sitemenu->getItems(array("component"), array("com_gallery"));
        foreach($galleryMenuitems as $menuitem)
        {
            if (strpos($menuitem->link, "view=$targetView") !== FALSE)  // if this menuitem's view matches
            {
                $query['Itemid'] = $menuitem->id;
                break;
            }
        }
    }
}  

$query['view'] is the view you asked for in your JRoute call.

$query['Itemid'] is the Itemid associated with the current menuitem that the Joomla router is using – which is (probably) going to be the menuitem the user is on.

The code finds the link associated with the current menuitem, and if it doesn't match the view you're looking for then it gets all your component's menuitems and searches through them to find a link which includes your view.

Alternatively if all your component views are named the same as the corresponding menuitem alias, then you can easily find that using

$menuitems = $sitemenu->getItems(array("component","alias"),array("com_gallery",$targetView), true);
if ($menuitems)
{
    $query['Itemid'] = $menuitems[0]->id;
}
