Extract Url & Title from link field in Drupal 8?

问题:

I'm trying to retrieve the URL and the Title values of a Link field in Drupal 8.

In my custom controller, I retrieve the nodes with:

$storage = \Drupal::entityManager()->getStorage('node');
$nids = $storage->getQuery()
    ->condition('type', 'partners')
    ->condition('status', 1)
    ->execute();

$partners = $storage->loadMultiple($nids);

When I loop throught all my nodes, to preprocess vars I'll give to my view, I would like to retrieve the URL and the Title.

foreach ($partners as $key => $partner) {
    $variables['partners'][] = array(
        'image' => $partner->field_logo->entity->url(),
        'url'   => $partner->field_link->value, // Can't retrieve values of link field
    );
}

Unfortunately, I don't found how to retrieve the URL and the Title of field_link.

Thanks for your help.

At the node level, inside your Twig template you can use:

{{ content.field_link.0['#url'] }} & {{ content.field_link.0['#title'] }}

For example:

<a href="{{ content.field_link.0['#url'] }}">{{ content.field_link.0['#title'] }}</a>

field_link being the name of the link field in question.

I just found the solution ...

$partner->field_lien->uri // The url
$partner->field_lien->title // The title

My bad, hope it could help someone.

Just to piggyback on the above, if you have an external link,

$node->field_name->uri

Will give you the URL, but if it's an internal you may need to tweak a bit more:

use Drupal\Core\Url;

$mylink = Url::fromUri($node->field_name[0]->uri);
$mylink->toString();

You can render either the uri or text of a link field directly in the twig template. In the case of a node you can use either of the following within the twig template file (assumes the machine name of your link field is field_link):

{{ node.field_link.uri }}

{{ node.field_link.title }}

Updated for Drupal 8

To get the url all you need to do is:

{{ content.field_link_name[0]['#url'] }}

To get the link text:

{{ content.field_link_name[0]['#title'] }}

回答6:

This one works for me in twig:

content.field_link_name.0['#title']        // title
content.field_link_name.0['#url_title']    // url value

*you should use: "Separate link text and URL" widget in display

I am doing this link separation for ECK fields and this solution really helped me. I have updated the code for ECK fields for apply inline style in twig file like this:

<a style="color: {{ entity.field_link_color[0] }};" href="{{ entity.field_link[0]['#url'] }}"> {{ entity.field_link[0]['#title'] }} </a>

To get url:
{{ entity.field_link[0]['#url'] }}

To get link title:
{{ entity.field_link[0]['#title'] }}

回答8:

After rendering a block if you want to access the link field used in it then you can use like this $render['field_target_url']['#items']->uri inside node preprocess hook.

One more way is to add another field Path:Content if you are trying to fetch the URL in Views Fields
