When I add an additional "onsubmit" function to the login button, the login doesnt continue this is my code function xxx_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id) { if ($form_id=='user_login_form') { // Add a custom submit handler to save the array of types back to the config file. $form['actions']['submit']['#submit'][] = 'xxx_form_submit'; } }

and it goes through the submit but doesnt continue the login functionality.

Use $form['#submit'][] = 'xxx_form_submit'; instead of $form['actions']['submit']['#submit'][] = 'xxx_form_submit';.
