How can I create a Link to an URL containing a fragment identifier?

Question

Is it possible to create a Link to a node with a hash in url (for opening a special Tab).

I use:

Link::createFromRoute('Title', 'entity.node.canonical', ['node' => 77]);

And I want to link to: "/node/77#example"

Answer 1

Please see public static function Link::createFromRoute

array $options: The options parameter takes exactly the same structure. See \Drupal\Core\Url::fromUri() for details.

You can pass a 4th argument as an array with a fragment key value:

Link::createFromRoute($this->t('Title'), 'entity.node.canonical', ['node' => 77], ['fragment' => 'example']);
