Code

function quotes_block_view($delta) {
  $quotes = '';

  // TODO Rename block deltas (e.g., delta-0) to readable strings.
  $block = db_select('quotes_blocks', 'qb')
    ->fields('qb')
    ->condition('qb.bid', $delta)
    ->execute()
    ->fetchAssoc();
  if (!$block) {
    return NULL;
  }

    if (!$block['vid'] || $block['cron_last'] + $block['cron_interval'] * $block['cron_step'] < REQUEST_TIME) {
      $block['vid'] = quotes_get_quote($block, TRUE, 1);
      db_update('quotes_blocks')
        ->fields(array(
        'vid' => $block['vid'][0],
