Php 将变量2传递给控制器

这是我的控制器代码：

public function search_records() {
    if($this->session->userdata('logged_in'))
    {
    $data = array (
    'employeeName' => $this->input->post('employeeName'),
    'userID' => $this->input->post('userID'),
    'date' => $this->input->post('date'),
    'timeSelect' => $this->input->post('timeSelect'),
    'error_message' => 'Sorry there is no record !'
    );

    if($data['employeeName'] !== '' OR $data['userID'] !== '') 
    {
        if(isset($data['date']))
        {
            if($data['timeSelect'] == 1)
            {
                $data['time1'] = '00:00:00';
                $data['time2'] = '23:59:00';
                $result_from_db= $this->mrecord->search_by_id_or_name_with_date($data);
                if($result_from_db == false)
                {
                    $data['show_search_error_message'] = 'Sorry, there is no record !';
                    $this->load->view('vhome', $data);
                }else {
                    $data['result_display'] = $result_from_db->result();
                    $data['row_count'] = count($result_from_db->result());
                    $this->session->set_userdata("excel_data", $result_from_db->result());
                    $this->pagi($data);
                }

            }else {
                $data['time1'] = '12:30:00';
                $data['time2'] = '15:30:00';
                $result_from_db = $this->mrecord->search_by_id_or_name_with_date($data);
                if($result_from_db == false)
                {
                    $data['show_search_error_message'] = 'Sorry, there is no record !';
                    $this->load->view('vhome', $data);
                }else {
                    $data['result_display'] = $result_from_db->result();
                    $data['row_count'] = count($result_from_db->result());
                    $this->session->set_userdata("excel_data", $result_from_db->result());
                    $this->pagi($data);
                }   
            }
        }else {
            $data['error_message'] = 'Something is wrong ! Please check your date .';
            $this->load->view('vhome', $data);
        }
    }else if(isset($data['date']))
    {
        if($data['timeSelect'] == 1)
        {
            $data['time1'] = '07:00:00';
            $data['time2'] = '19:00:00';
            $result_from_db = $this->mrecord->search_by_date($data);
            if($result_from_db == false)
            {
                $data['error_message'] = 'Sorry, there is no record !';
                $this->load->view('vhome', $data);
            }else {
                $data['result_display'] = $result_from_db->result();
                $data['row_count'] = count($result_from_db->result());
                $this->session->set_userdata("excel_data", $result_from_db->result());
                $this->pagi($data);
            }
        }else {
            $data['time1'] = '12:30:00';
            $data['time2'] = '15:30:00';
            $result_from_db = $this->mrecord->search_by_date($data);
            if($result_from_db == false)
            {
                $data['error_message'] = 'Sorry, there is no record !';
                $this->load->view('vhome', $data);
            }else {
                $data['result_display'] = $result_from_db->result();
                $data['row_count'] = count($result_from_db->result());
                $this->session->set_userdata("excel_data", $result_from_db->result());
                $this->pagi($data);
            }
        }
    } else {
        $data['error_message'] = 'Oops ... you can not search without input !';
        $this->load->view('vhome', $data);
    }
 }else {
     redirect ('welcome', 'refresh');
 }

这是我的模型：

public function search_by_id_or_name_with_date($data) {
    if($data['userID'] == '')
    {
    $condition = "employeeName =" . "'" . $data['employeeName'] . "'";
    }else {
        $condition = "employeeID =" . "'" . $data['userID'] . "'";
    }
    $condition2 = "date =" . "'" . $data['date'] . "'";
    $condition1 = "time BETWEEN " . "'" . $data['time1'] . "'" . "AND" . "'" . $data['time2'] . "'";
    $this->db->select('employeeID, employeeName, departmentName, date, time, tb_inout.doorStatus');
    $this->db->from('tb_access_logs');
    $this->db->join('tb_inout', 'tb_access_logs.doorID = tb_inout.doorID');
    $this->db->where($condition);
    $this->db->where($condition1);
    $this->db->where($condition2);
    $query = $this->db->get();

    if ($query->num_rows() > 0) {
        return $query;
    } else {
        return false;
    }
}

public function search_by_date($data) {
    $condition = "date =" . "'" . $data['date'] . "'";
    $condition1 = "time BETWEEN " . "'" . $data['time1'] . "'" . "AND" . "'" . $data['time2'] . "'";
    $this->db->select('employeeID, employeeName, departmentName, date, time, tb_inout.doorStatus');
    $this->db->from('tb_access_logs');
    $this->db->join('tb_inout', 'tb_access_logs.doorID = tb_inout.doorID');
    $this->db->where($condition);
    $this->db->where($condition1);
    $query = $this->db->get();

    if($query->num_rows() > 0) {
        return $query;
    }else {
        return false;
    }
}

以下是我的看法：
