I'm currently writing Report's system. I have about 20 different users with different access. Am I doing it correctly? Can I improve my style of writing this code? All my reports based on the same structure.

In my Report's Controller:

function my_report_name() 
    {
        //current week by default
        $dates['from'] = $this->uri->segment(3,date('Y-m-d',strtotime(date('o-\\WW'))-60*60*24*7)); 
        $dates['to'] = $this->uri->segment(4,date("Y-m-d", strtotime($dates['from']) + 6 * 24* 60 * 60));

        $data['report_name']=$this->Reports_model->getMyReportDescriptionSummary($dates);
        
        $data['title'] = "My Report Name Description";
        //view in 'view/report' folder to use
        //name of view always the same as name of function
        $data['main'] = "report/my_report_name";
        $data['menuReport'] = "class='current'";
        $data['panel'] = "panel/panel";

        $this->load->vars($data);
        //load template
        $this->load->view('template/t_main_full', $data);

    }

In my Model:

function getMyReportDescriptionSummary($dates)
    {
        $this->db->select("some_data,
                           some_data_2,
                           some_data_3"
                          );
        $this->db->join("table1");
        $this->db->join("table2");
        $this->db->where("some_params");
        $Q = $this->db->get();

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

In my repots layout page:

//function to check permissions
<? if($this->Model_Users->accessVerify('my_report_name')) {?>
<tr>My report</tr>
<?}?>
