Allows you to add a recurring fee to a product/SKU to handle subscription type services.

Code

function uc_recurring_cron() {
  $successes = 0;
  $fails = 0;

  // Look for any fees ready for a charge that are reference transactions
  // routed through the core recurring system.
  $result = db_query("SELECT * FROM {uc_recurring_users} WHERE fee_handler LIKE 'uc_recurring_byref:%%' AND remaining_intervals > 0 AND next_charge <= %d", time());
  while ($fee = db_fetch_array($result)) {
    $handler = explode(':', $fee['fee_handler']);
    $fee['data'] = unserialize($fee['data']);

    // Attempt to process the reference transaction.
    if (uc_recurring_charge($fee)) {

      // Update the fee in the database.
      if ($fee['remaining_intervals'] == 1) {
        $next_charge = time();
      }
      else {
        $next_charge = strtotime('+' . $fee['regular_interval'], $fee['next_charge']);
