Change upload path

Files uploaded as field respect field path settings. For files uploaded via the provider's form (Scald Flash, Scald Audio...), use hook_form_FORM_ID_alter() to modify the path. For example, to change Flash path to the 'atoms/swf/YYYY/mm/dd' structure:

function mymodule_form_scald_atom_add_form_add_alter(&$form, $form_state, $form_id) {
  if ($form_state['scald']['source'] == 'scald_flash') {
    $form['file_swf']['#upload_location'] = 'public://atoms/swf/' . date('Y/m/d');
  }
}
