cakephp-3.0 - Cakephp 3 如何在数据库中保存单个日期

Question

我有请假申请表。如果用户请假2/3天，那么请假日期应该单独存储到数据库中。我申请了2天，假设我选择了20-10-2019和21-10- 2019 年请假。但是它只存储了一个条目到数据库中。 date_form 和 date_to 是我的列名。
我想分开日期。示例: date_from: 20-10-2019 date_to : 20-10-2019 和 date_from: 21-10-2019 date_to : 21-10-2019。
但现在它存储了 date_from : 20-10-2019 date_to : 21-10-2019。谁可以帮我这个事？

我试过一些代码:

            else if($leaveRequest->no_of_days > 1 && $leaveRequest->no_of_days < 7)
            {
            for($i = 0 ; $i < $leaveRequest->no_of_days; $i++)
            {
                $day = $i. ' day';
                $var = $this->EmpLeaves->newEntity();

                if($i == 0)
                {
                $var->date_from = date('Y-m-d', strtotime($this->request->getData(['date_from'])));
                $var->date_to = date('Y-m-d', strtotime($this->request->getData(['date_from'])));
                }

                else
                {
                $var->date_from = date('Y-m-d', strtotime($day,strtotime($this->request->getData(['date_from']))));
                $var->date_to = date('Y-m-d', strtotime($day,strtotime($this->request->getData(['date_from']))));
                }

                $var->employee_id = $this->Auth->user('id');
                $var->employee_name = $this->request->getData(['employee_name']);
                $var->reporting_managerId = $this->request->getData(['reporting_managerId']);
                $var->leave_type = $this->request->getData(['leave_type']);
                // $var->no_of_days = $this->request->getData(['no_of_days']);
                 $var->no_of_days = 1;
                $var->half_day = $this->request->getData(['half_day']);
                $var->leave_reason = $this->request->getData(['leave_reason']);
                $var->reliever = $this->request->getData(['reliever']);
                $valueSaved = $this->EmpLeaves->save($var);
            }

            if($valueSaved)
            {
                //newcode for sending email
                 $applierEmail = $this->Auth->user('office_email');
                $applierName  = $this->Auth->user('first_name') . ' ' . $this->Auth->user('last_name');

            }
            else
            {
                $this->Flash->error(__('Please check the message'));
            }
        }

        }
    }
