Data not passing from Controller to View Code Igniter

Question

I am puzzled because of CodeIgniter's strange behavior. I am fetching some data from Model and returning it to Controller and passing that data from Controller to View.

function index()
    {
        $data['details'] = $this->Mymodel->Get_Details();
        $this->load->view('mypage',$data);
    }

public function Get_Details() 
    {
        $query = "
                    SELECT 
                            *
                    FROM 
                            tablename
                 ";

        $result = $this->db->query($query)->result();
        return $result;
    }

<?php 
 print_r($details); 
?>

The problem is nothing is displayed in view page. If i give print_r($data); in Controller or print_r($result); in Model , the result is shown. If in select , * is replaced with individual column names then the output is passed from Controller to View and output is shown.
By any chance is there any limit to passing data from controller to view?

In view if i use print_r($details[0]); 鉴于我是否使用print_r($details[0]); or print_r($details[n]); the result is printed. If print_r($details); is used then page is just blank. What could be the problem?

Answer 1

try this in the model

public function Get_Details() 
{
    $query = "
                SELECT 
                        *
                FROM 
                        tablename
             ";

    $result = $this->db->query($query);
    return $result->result();
}

Have you tried this code :

Model

    public function Get_Details() 
    {
        $query = "
                    SELECT 
                            *
                    FROM 
                            tablename
                 ";

        return $this->db->query($query);
    }

View

<?php 
 print_r($details->result()); 
?>

The result() function returns the query result as an array of objects, or an empty array on failure.

You will need to loop through it in your view to get the expected results.
