Description

In lots of cases, a request will provide a contentId or a locationId. Before using them, you will have to load API object within your controller.

Solution

For example:

public function listBlogPostsAction( $locationId )
{
	$location = $repository->getLocationService()->loadLocation( $locationId );

Thanks to the param converter, you can directly have the API object at your disposal. All you have to do is:

• For Locations:
  • In your controller's signature, type int the variable to Location.
  • Make sure a parameter named "locationId" is provided by the request.
• For Content items:
  • In your controller's signature, typeint the variable to Content
  • Make sure a parameter named "contentId" is provided by the request

Example

Example using Locations:

use eZ\Publish\API\Repository\Values\Content\Location;

public function listBlogPostsAction( Location $location )
{
	// use my $location object
