Migrate Upload Source

Provides an upload widget for your migration users to be able to upload source files (CSV, XML, etc) through the UI.

Very experimental, don't use it as is, without reviewing the code and making the modifications that suit your needs.

After installing this module you'll see a new TAB under /admin/content/migrate, to "Upload Source File". Once the source file is uploaded, you can use it in your migrate class by retrieving the value of the variable "migrate_upload_source_file_path".

An example of implementation could be:

    // (...)
    $sourcefile = variable_get('migrate_upload_source_file_path');
    if (!empty($sourcefile)) {
      $source_path = DRUPAL_ROOT . '/' . $sourcefile;
      $this->source = new MigrateSourceCSV($source_path, $columns, $options);
    }
    else {
      drupal_set_message(t('You need to upload a file in order to be able to use this migration class.'), 'warning');
      $this->source = new MigrateSourceCSV('foo.txt', $columns, $options);
    }
    // (...)
