public function BlockBase::getMachineNameSuggestion

public BlockBase::getMachineNameSuggestion()

Suggests a machine name to identify an instance of this block.

The block plugin need not verify that the machine name is at all unique. It is only responsible for providing a baseline suggestion; calling code is responsible for ensuring whatever uniqueness is required for the use case.

Return value

string The suggested machine name.

Overrides BlockPluginInterface::getMachineNameSuggestion

Code

public function getMachineNameSuggestion() {
  $definition = $this->getPluginDefinition();
  $admin_label = $definition['admin_label'];

  // @todo This is basically the same as what is done in
  //   \Drupal\system\MachineNameController::transliterate(), so it might make
  //   sense to provide a common service for the two.
  $transliterated = $this->transliteration()->transliterate($admin_label, LanguageInterface::LANGCODE_DEFAULT, '_');
  $transliterated = Unicode::strtolower($transliterated);

  $transliterated = preg_replace('@[^a-z0-9_.]+@', '', $transliterated);
