Using JRoute::_() in Joomla administrator

I have a custom component I'm working on and I'm writing an import script which is running in the administration area. I have the following code:

$newUrl = ContentHelperRoute::getArticleRoute($import->article_id.':'.$import->alias, $import->catid);
$newUrl = JRoute::_($newUrl);

the first part works returning similiar to this:

index.php?option=com_content&view=article&id=45:joomla-sociable-and-sh开发者_Go百科arethis-module&catid=18

the second part shows it like this:

/administrator/index.php?option=com_content&view=article&id=45:joomla-sociable-and-sharethis-module&catid=18

Both of the above urls are as you'd expect the component com_content to render these urls as if I wanted to use them within the administration area.

Any idea how to force JRoute to work as it would when used in the frontend?

NB: This is being used within a controller of my component, if it makes any difference and I'm including require_once (JPATH_SITE . '/components/com_content/helpers/route.php');

For those who find this on Google and struggle with using JRoute::_() and contentHelper::getArticleRoute().

$newUrl = ContentHelperRoute::getArticleRoute($import->article_id.':'.$import->alias, $import->catid);

// better will be check if SEF option is enable!
$router = new JRouterSite(array('mode'=>JROUTER_MODE_SEF));
$newUrl = $router->build($newUrl)->toString(array('path', 'query', 'fragment'));
// SEF URL !
$newUrl = str_replace('/administrator/', '', $newUrl);
//and now the tidying, as Joomlas JRoute makes a cockup of the urls.
$newUrl = str_replace('component/content/article/', '', $newUrl);

Here's a snippet that will work for Joomla 3.6

$routerOptions = [];
if (JFactory::getConfig()->get('sef')) {
    $routerOptions['mode'] = JROUTER_MODE_SEF;
}
$siteRouter = JRouter::getInstance('site', $routerOptions);
$link = $siteRouter->build($yourRoute)->toString();
$link = preg_replace('#^/administrator#', '', $link);

A nicer solution would be to create a new router instance, so, the code will be something like this:

$app    = JApplication::getInstance('site');
$router = &$app->getRouter();    

$newUrl = ContentHelperRoute::getArticleRoute($import->article_id.':'.$import->alias, $import->catid);

$newUrl = $router->build($newUrl);
$parsed_url = $newUrl->toString();
$parsed_url = str_replace('/administrator', '', $parsed_url);

This way you will always obtain the right URL for the item, no matter if it is a joomla article, K2 article, etc...

** Notice that depending on the type of the item ( k2, joomla, etc) , $newUrl should be obtained with the consequent method.

---

I think that this one would be an easier solution:

$newUrl = JRoute::_(ContentHelperRoute::getArticleRoute($import->id.':'.$import->alias, $import->catid));

This will give you the same result as the other two previous answers but with less coding.

Hope this helps.

In Joomla 3.9 they extended the JRoute class (now called Route class) to include a link() static method which solves this problem.

use Joomla\CMS\Router\Route;
$newUrl = ContentHelperRoute::getArticleRoute($import->article_id.':'.$import->alias, $import->catid);
$newUrl = Route::link("site", $newUrl);

Route::link() works just the same as Route::_() except that you can must provide the additional first parameter to specify the client you want the URL built for. See https://api.joomla.org/cms-3/classes/Joomla.CMS.Router.Route.html#method_link.
