Question

尝试在我的映射器中获取最后一个插入ID 我有这段代码：

        $sql = new Sql($this->dbAdapter);
        $stmt = $sql->prepareStatementForSqlObject($action);
        $result = $stmt->execute(); 

        return array('success' => $result->getAdapter()->lastInsertId());

我遇到的问题是我遇到致命错误：（！）致命错误：在/ var / www / zf-skeleton中调用未定义的方法Zend \ Db \ Adapter \ Driver \ Pdo \ Result :: getAdapter（）第100行的/module/Application/src/Application/Mapper/ZendDbSqlMapper.php

我似乎无法获得适配器，尽管数据已添加到数据库中。

感谢任何帮助。

        } catch(\Exception $e) {}

        throw new \Exception('Database error');

    }

}

Answer 1

试试这个：

return array('success' => $db->lastInsertId());

或

return array('success' => $Table->getAdapter()->lastInsertId());

Answer 2

我找到了如何做到这一点：

        $sql = new Sql($this->dbAdapter); // Same
        $stmt = $sql->prepareStatementForSqlObject($action); // Same
        $result = $stmt->execute(); // Same
        return array('success' => $result->getGeneratedValue()); // <-- New
