File names transliteration

Confirming that is a bug.

This is a transliteration module issue. Its hook_init should be rewritten to support the multiple html5 attribute.

The transliteration module supports multiple file upload. The bug occurs because the attribute name of multiupload input is not "files", so it cannot be taken by $_FILES['files'] in transliteration_init().

I tried to fix the code. This works for me, but is applied to all files in $_FILES:

function transliteration_init() {
  //Apply to all files in $_FILES
  if (!empty($_FILES) && variable_get('transliteration_file_uploads', TRUE)) {
    // Figure out language, which is available in $_POST['language'] for node
    // forms.
    $langcode = NULL;
    if (!empty($_POST['language'])) {
      $languages = language_list();
      if (isset($languages[$_POST['language']])) {
        $langcode = $_POST['language'];
      }
    }

    foreach($_FILES as &$file) {
      // multiple files
      if(is_array($file['name'])) { 
        foreach ($file['name'] as $field => $filename) {
          // Keep a copy of the unaltered file name.
          $file['orig_name'][$field] = $filename;
          $file['name'][$field] = transliteration_clean_filename($filename, $langcode);
        }
      }
      // single file
      else {
        $filename = $file['name']; 
        $file['orig_name'] = $filename;
        $file['name'] = transliteration_clean_filename($filename, $langcode);
      }
    }
  }
}

Sorry, my english is not good.

Same issue in the D6 version of transliteration.

I was wrong, this turned out to be an MFW issue.
As there's a patch here:

I mark this as duplicate.
