Knowledge of the root location is important since it can be a starting p= oint for API queries, or even links to home page, but as eZ Platform can be= used for multisite development, the root location can vary.
By default, the root location ID is 2, but as it can be eas=
ily be changed by configuration, the best practice is to retrieve i=
t dynamically.
Root location ID can be retrieved easily from ConfigResolver. The =
parameter name is content.tree_root.location_id .
<?php
namespace Acme\TestBundle\Controller;
use eZ\Bundle\EzPublishCoreBundle\Controller;
class DefaultController extends Controller
{
public function fooAction()
{
// ...
$rootLocationId =3D $this->getConfigResolver()->getParameter(=
'content.tree_root.location_id' );
// ...
}
}=20
Root location is exposed in the global Twig helper.
<a href=3D"{{ path( ezpublish.rootLocation ) }}" title=3D"L=
ink to homepage">Home page</a>=20
<?php
namespace Acme\TestBundle\Controller;
use eZ\Bundle\EzPublishCoreBundle\Controller;
class DefaultController extends Controller
{
public function fooAction()
{
// ...
$rootLocation =3D $this->getRootLocation();
// ...
}
}=20
