I'm trying to add attributes for external links such as the rel="noopener noreferrer" for all the external links where target="_blank". I've tried using modules such as the noreferrer and sel, but neither affect the links in my views.
How can I add rel="noopener noreferrer" to all links globally where target="_blank"?
By implementing hook_link_alter in either a custom module or your theme.
The code (untested) would be similar to:
/**
* Implements hook_link_alter().
*/
function MODULE/THEME_link_alter(&$variables) {
if (isset($variables['options']['attributes']['target']) && $variables['options']['attributes']['target'] == '_blank') {
$variables['options']['attributes']['rel'] = 'noopener noreferrer';
}
}
noopener noreferrer. The Noopener Filter module does it like above, but adds if (empty($variables['options']['attributes']['rel']) || !in_array('noopener', $variables['options']['attributes']['rel'], TRUE)) {. It also has it as an array, not a string. Like $variables['options']['attributes']['rel'][] = 'noopener';
