$transaction = isset($transaction) ? $transaction : db_transaction();
try {
$ids = array_keys($entities);
db_delete($this->entityInfo['base table'])
->condition($this->idKey, $ids, 'IN')
->execute();
if (isset($this->revisionTable)) {
db_delete($this->revisionTable)
->condition($this->idKey, $ids, 'IN')
->execute();
}
// Reset the cache as soon as the changes have been applied.
$this->resetCache($ids);
foreach ($entities as $id => $entity) {
$this->invoke('delete', $entity);
}
// Ignore slave server temporarily.
db_ignore_slave();
}
catch (Exception $e) {
$transaction->rollback();
watchdog_exception($this->entityType, $e);
throw $e;
}
以上代码片段为使用db_transaction范式。摘抄自entity模块。
