function advagg_file_create_url in Advanced CSS/JS Aggregation 6

Same name and namespace in other branches

1. 7.2 advagg.module \advagg_file_create_url()

Create the download path to a file.

There are two kinds of local files:

• "created files", i.e. those in the files directory (which is stored in the file_directory_path variable and can be retrieved using file_directory_path()). These are files that have either been uploaded by users or were generated automatically (for example through CSS aggregation).
• "shipped files", i.e. those outside of the files directory, which ship as part of Drupal core or contributed modules or themes.

Parameters

$path: A string containing the Drupal path (i.e. path relative to the Drupal root directory) of the file to generate the URL for.

Return value

A string containing a URL that can be used to download the file.

function advagg_file_create_url($path) {

  // Clean up Windows paths.
  $old_path = $path = str_replace('\\', '/', $path);
  drupal_alter('file_url', $path);

  // If any module has altered the path, then return the alteration.
  if ($path != $old_path) {
    return $path;
  }

  // Otherwise serve the file from Drupal's web server. This point will only
  // be reached when either no custom_file_url_rewrite() function has been
  // defined, or when that function returned FALSE, thereby indicating that it
  // cannot (or doesn't wish to) rewrite the URL. This is typically because
  // the file doesn't match some conditions to be served from a CDN or static
  // file server, or because the file has not yet been synced to the CDN or
  // static file server.
  // Shipped files.
