如何从多个嵌套的if条件中调用json
我正在使用CodeIgniter。 我正在处理批量列表的小项目。 现在如果管理员想要创建批处理列表，那么应该输入开始日期和结束日期以及开始时间和结束时间，然后它将在数据库中检查批处理在相同的日期和时间运行？ 如果是，那么它将显示消息，否则它将创建新的批次列表。
如果日期相同，则时间应该不同。
现在我的逻辑是，我将第一个new_start_date与exist_start_date和exist_end_date进行比较，如果在中间找到了日期，那么它将检查时间。
它的工作直到日期比较。 即使它正在检查时间，但从那里如何退出进程并调用JSON？ 因为从那里我的JSON无法正常工作。
我添加"echo "time not match";" 从那里我无法调用JSON我在网络选项卡上获得输出。
我得到了输出
enter 1enter 2{"error":true,"msg":"Batch Created"}time not match
你能帮助我吗？

你能在这个问题上帮助我吗？
你的整个方法有点乱，因为你发现自己有大量的冗余代码片段，没有人能够理解你想要什么 – 我在这里给你一些提示，包括一个基于你的代码的例子
- 使用例外 – 它非常适合你的情况 – 如果出现问题 – 停止它
- 尝试过滤您对一个单一任务的需求并尝试解决它 – 并且只有在那之后转到下一个任务
- 永远 – 永远记住 – 想想一个术语 – 如果你在你的应用程序中反复找到相同的代码 – 你知道有些错误 – 你应该重构它 – 不要为冗余而感到羞耻 – 它们总是会发生 – 但如果你发现他们，你必须重构那些代码片段
现在举个例子
你在这做什么工作？
- 如果批处理已经在运行，您可以尝试询问您的数据库 – 您不需要遍历整个表条目
- 比较管理员的两个输入日期 – 如果开始日期是结束日期的未来，则立即停止应用程序
- 你的交集对我来说并不是很清楚你想要在这里实现什么 – 但我真的相信你也可以在这里询问数据库（
find_in_set：find_in_set）
基于这些信息，我们现在可以开始开发;）（如果我没有完成上面的列表并尝试实现您的任务）
控制器：
try { $id = $this->input->post('venue_id'); $venue_id = implode(',',$id); $activity_list_id = $this->input->post('activity_name'); $new_batch_start_date = date('Ym-d',strtotime($this->input->post('start_date'))); $new_batch_end_date = date('Ym-d',strtotime($this->input->post('end_date'))); $new_batch_start_time = $this->input->post('start_time'); $new_batch_end_time = $this->input->post('end_time'); $days = implode(',',$this->input->post('days')); $objDateStart = DateTime::createFromFormat('Ymd h:i a', $new_batch_start_date.' '.$new_batch_start_time); $objDateEnd = DateTime::createFromFormat('Ymd h:i a', $new_batch_end_date.'

Please Change Time Slot for Start and End Date'); $data = array( 'activity_list_id' => $this->input->post('activity_name'), 'batch_venue_id' => $venue_id, 'batch_name' => $this->input->post('batch_name'), 'start_date' => $objDateStart->format('Ym-d'), 'end_date' => $objDateEnd->format('Ym-d'), 'start_time' => $objDateStart->format('H:i'), 'end_time' => $objDateEnd->format('H:i'), 'total_capacity' => $this->input->post('total_capecity'), 'batch_status' => 1, 'created_by' => trim($this->session->userdata['login_data']['user_id']), 'created_date' => date('dmY h:i:s A'), 'batch_days' => $days ); $this->Batch_model->createBatch($data); } catch(Exception $e) { $arrError = [ 'error' => false, 'msg' => $e->getMessage() ]; echo json_encode($arrError); }
模型：
public function hasBatchesBetweenDates(DateTime $objDateStart, DateTime $objDateEnd) { $query = $this->db ->from('batch_list') ->join('activity_list','activity_list.activity_id = batch_list.activity_list_id') ->where('CONCAT(start_date,\' \',start_time) >=', $objDateStart->format('Ymd H:i:s')) ->or_group_start() ->where('CONCAT(end_date, \' \', end_time) <=', $objDateEnd->format('Ymd H:i:s')) ->where('CONCAT(end_date, \' \', end_time) >=', $objDateStart->format('Ymd H:i:s')) ->group_end() ->get(); return ($query->num_rows() > 0); }
我希望你理解这里的概念 – 如果你有问题 – 请不要犹豫
