Drupal 8 - How to add link & display in twig template

Question

I have file in src/Form/TestForm.php.

I would like to add link of Forgot password in buildForm function & want to display in twig template file.

How to achieve this?

Answer 1

You should add the link in the form builder, something like the following example:.

$forgot_password_link = \Drupal\Core\Link::createFromRoute($this->t('Password link'), 'user.pass')->toRenderable();
$form['forgot_password_link'] = [
  '#markup' => render($forgot_password_link),
];

Answer 2

You can add links in Twig directly:

<a href="{{ path('user.pass') }}">{{ 'Forgot password?'|t }}</a>
