本文实例讲述了Symfony2针对输入时间进行查询的方法。分享给大家供大家参考,具体如下:
一般情况下:前端输入一个时间,我们一般是先将时间修改成一个时间戳
strtotime — 将任何英文文本的日期时间描述解析为 Unix 时间戳
例如:
$startTimestamp = strtotime($startDate);$endTimestamp = strtotime($endDate);
然后:如果只是时间,为防止别人传的时间是造假,需要将时间都修改成Y-m-d的形式
$start = date('Y-m-d 00:00:00', $startTimestamp);$end = date('Y-m-d 23:59:59', $endTimestamp);
1. 在MySQL中的使用
if(empty($startDate)) { throw new /Exception('起始时间不为空', BaseException::ERROR_CODE_ILLEGAL_PARAMETER);}if (empty($endDate)) { $endDate = $startDate;}$startTimestamp = strtotime($startDate);$endTimestamp = strtotime($endDate);if ($startTimestamp > $endTimestamp) { throw new /Exception('时间参数错误', BaseException::ERROR_CODE_ILLEGAL_PARAMETER);}if ($status == InventoryOrder::STATUS_SUBMITTED) { $index = 'i.submitTime';} else if ($status == InventoryOrder::STATUS_UNSUBMITTED) { $index = 'i.createTime';} else if (empty($status)) { $index = 'i.createTime';} else { throw new /Exception('时间格式不正确', BaseException::ERROR_CODE_ILLEGAL_PARAMETER);}$sql = 'SELECT i FROM AppBundle:InventoryOrder i WHERE ';$sql .= $index;$sql .= ' BETWEEN :startDate AND :endDate ';$start = date('Y-m-d 00:00:00', $startTimestamp);$end = date('Y-m-d 23:59:59', $endTimestamp);$params['endDate'] = $end;$params['startDate'] = $start;if (!empty($status)) { $sql .= ' AND i.status = :status'; $params['status'] = $status;}$sql .=' ORDER By i.createTime DESC';$query = $this->entityManager->createQuery($sql);$orderList = $query->setParameters($params)->getResult();
2. 在mongodb中的时间的输入和查询列子
在这里面其实有两个坑:
@ ->field('submit_time')->gt(new /DateTime($start))->field('submit_time')->lt(new /DateTime($end))
这里面,对于时间的查询,大于和小于,一定要传一个对象。
$query->field('status')->equals($status);
这里面,在mongodb里面不会默认帮你识别这是一个int型,是什么类型,必须手动的传入。
$data = array();if (!isset($startDate)) { throw new /Exception("参数不正确", BaseException::ERROR_CODE_ILLEGAL_PARAMETER);}if (empty($endDate)) { $endDate = $startDate;}$startTimestamp = strtotime($startDate);$endTimestamp = strtotime($endDate);if ($startTimestamp > $endTimestamp) { throw new /Exception("参数不正确", BaseException::ERROR_CODE_ILLEGAL_PARAMETER);}$start = date('Y-m-d 00:00:00', $startTimestamp);$end = date('Y-m-d 23:59:59', $endTimestamp);$scanner = Order::FROM_TYPE_SCANNER;$query = $this->documentManager ->createQueryBuilder('AppBundle:Order') ->field('submit_time')->gt(new /DateTime($start)) ->field('submit_time')->lt(new /DateTime($end)) ->field('from_type')->equals("$scanner");if (!empty($status) && in_array($status, array(Order::STATUS_CANCELLED, Order::STATUS_SUBMITTED))) { $status = $status + 0; $query->field('status')->equals($status);} else if (empty($status)) { $status = Order::STATUS_SUBMITTED + 0; $query->field('status')->equals($status);} else { throw new /Exception("参数不正确", BaseException::ERROR_CODE_ILLEGAL_PARAMETER);}$orderList = $query->sort('create_time', 'DESC') ->getQuery() ->execute();
