CssOptimizer::rewriteFileURI

public CssOptimizer::rewriteFileURI($matches)

Prefixes all paths within a CSS file for processFile().

Note: the only reason this method is public is so color.module can call it; it is not on the AssetOptimizerInterface, so future refactorings can make it protected.

Parameters

array $matches: An array of matches by a preg_replace_callback() call that scans for url() references in CSS files, except for external or absolute ones.

Return value

string The file path.

File

core/lib/Drupal/Core/Asset/CssOptimizer.php, line 250

Class

CssOptimizer
Optimizes a CSS asset.

Namespace

Drupal\Core\Asset

Code

public function rewriteFileURI($matches) {
  // Prefix with base and remove '../' segments where possible.
  $path = $this->rewriteFileURIBasePath . $matches[1];
  $last = '';
  while ($path != $last) {
    $last = $path;
    $path = preg_replace('`(^|/)(?!\.\./)([^/]+)/\.\./`', '$1', $path);
  }
  return 'url(' . file_url_transform_relative(file_create_url($path)) . ')';
}
