Viewfield provides a field that holds a reference to a View and renders it whenever the entity containing the field is displayed.
Viewfield Project on drupal.org
When working on a recent project they were using the Viewfield contrib module to allow the option to render a view display as a field.
use Drupal\views\Views;
// Firstly, get the view in question.
$view = Views::getView('view_machine_name');
// Set which view display we want.
$view->setDisplay('view_display_name');
// Pass any arguments that the view display requires.
$view->setArguments([$entity->id()]);
// Execute the view.
$view->execute();
$view_result = $view->result;
// Access field data from the view results.
foreach ($view_result as $data) {
$entity = $data->_entity;
$title = $entity->getTitle();
$body = $entity->get('body')->value;
// Do whatever you want with the data.
}
This is a quick summary of what I did to dig into the viewfield and retrieve the field data from the output. If there is a cleaner more efficient way to achieve this then please leave a comment below.
