function hook_contextual_links_alter

hook_contextual_links_alter(array &$links, $group, array $route_parameters)

Alter contextual links before they are rendered.

This hook is invoked by \Drupal\Core\Menu\ContextualLinkManager::getContextualLinkPluginsByGroup(). The system-determined contextual links are passed in by reference. Additional links may be added and existing links can be altered.

Each contextual link contains the following entries:

• title: The localized title of the link.
• route_name: The route name of the link.
• route_parameters: The route parameters of the link.
• localized_options: An array of URL options.
• (optional) weight: The weight of the link, which is used to sort the links.

Parameters

array $links: An associative array containing contextual links for the given $group, as described above. The array keys are used to build CSS class names for contextual links and must therefore be unique for each set of contextual links.

string $group: The group of contextual links being rendered.

array $route_parameters.: The route parameters passed to each route_name of the contextual links. For example:

  array('node' => $node->id())
