4. 9 core/modules/path_alias/src/AliasRepository.php \Drupal\path_alias\AliasRepository::preloadPathAlias()

Pre-loads path alias information for a given list of system paths.

Parameters

array $preloaded: System paths that need preloading of aliases.

string $langcode: Language code to search the path with. If there's no path defined for that language it will search paths without language.

Return value

string[] System paths (keys) to alias (values) mapping. If match to path in $preload differs by case, the array will contain an entry for the stored path and the provided path. The stored path will be returned first.

Overrides AliasRepositoryInterface::preloadPathAlias

File

core/modules/path_alias/src/AliasRepository.php, line 35

Class

AliasRepository

Provides the default path alias lookup operations.

Namespace

Drupal\path_alias

Code

public function preloadPathAlias($preloaded, $langcode) {
  $select = $this->getBaseQuery()
    ->fields('base_table', [
    'path',
    'alias',

  // Use a map of paths to their lowercase equivalents to look up aliases so
  // the returned array will contain an exact match to the provided path if it
  // differs by case to the stored path.
  $path_map = [];

    }
    $select->condition($conditions);
  }
  $this->addLanguageFallback($select, $langcode);
  $select->orderBy('base_table.id', 'DESC');
  // We want the most recently created alias for each source, however that
  // will be at the start of the result-set, so fetch everything and reverse
  // it. Note that it would not be sufficient to reverse the ordering of the
  // 'base_table.id' column, as that would not guarantee other conditions
  // added to the query, such as those in ::addLanguageFallback, would be
  // reversed.

    // the alias's path does not have an exact match, then look up the path
    // provided by the user in the map.
