How to open a link in a new tab? - php

Question

I created a custom module for Drupal 8
I want my link to open in a new tab, but it does not work.
Yet I added ['attributes' => ['target' => '_blank']]
Why does not it work ?
<?php
namespace Drupal\commerce_agree_cgv\Plugin\Commerce\CheckoutPane;
use Drupal\Core\Form\FormStateInterface;
use Drupal\commerce_checkout\Plugin\Commerce\CheckoutPane\CheckoutPaneBase;
use Drupal\commerce_checkout\Plugin\Commerce\CheckoutPane\CheckoutPaneInterface;
use Drupal\Core\Link;
use Drupal\Core\Url;
/**
* Provides the completion message pane.
*
* #CommerceCheckoutPane(
* id = "agree_cgv",
* label = #Translation("Agree CGV"),
* default_step = "review",
* )
*/
class AgreeCGV extends CheckoutPaneBase implements CheckoutPaneInterface {
/**
* {#inheritdoc}
*/
public function buildPaneForm(array $pane_form, FormStateInterface $form_state, array &$complete_form) {
$pane_form['cgv'] = [
'#type' => 'checkbox',
'#default_value' => FALSE,
'#title' => $this->t('I have read and accept the general terms and conditions of business.', ['#cgv' => Url::fromRoute('entity.commerce_store.canonical', ['commerce_store' => 3], ['attributes' => ['target' => '_blank']])->toString()]),
'#required' => TRUE,
'#weight' => $this->getWeight(),
];
return $pane_form;
}
}

Answer 1

Its normal URL::fromRoute return path, not link
you have 2 solution her:
1 - use Link
$options = ['absolute' => TRUE, 'attributes' => ['target' => '_blank']];
$link_object = Drupal\Core\Link::createFromRoute(t('the general terms and conditions of business'),
'entity.node.canonical', ['node' => "123"],
$options);
$link = $link_object->toString();
and the result : the general terms and conditions of business
or
2 - use URL
'#title' => $this->t('I have read and accept the general terms and conditions of business.', ['#cgv' => Url::fromRoute('entity.commerce_store.canonical', ['commerce_store' => 3], ['absolute' => true])->toString()]),
i hope this helps.
