Passing result array to controller in codeigniter - arrays

Question

I am developing a simple profile page but I am having a little dificulty passing the result array to the controller..am not sure if this how to do it.
Model:
class Login_model extends CI_Model{
function get_profile()
{
$this->db->where('email', $this->input->post('email'));
$query = $this->db->get('user');
if($query->num_rows == 1)
{
return $query->result_array();
}
}
}
Controller:
class Login extends CI_Controller {
function show_profile{
$this->load->model('login_model');
$q['user'] = $this->login_model->get_profile();
echo $q['user'];
}
}
I tried to echo out $q['user'] as a tests to see if it will work, but it did not work.

Answer 1

in this context a result array would be if you were getting back more then one result. since you are only getting back one result you can do row_array() so like
if($query->num_rows == 1)
{
return $query->row_array();
}
else
{
return false;
}
NEVER do this
// example of what NOT to do
$this->db->where('email', $this->input->post('email'));// NO NO NO
validate the email first using codeigniter form validation and then send it like
// if no user comes back then deal with it right away
if( ! $user = $this->login_model->get_profile($email) )
{
$this->showNoUserFor($email) ;
}
else
{ // carry on....
otherwise - do the tutorial first in the codeigniter manual, it will save you a lot of time.

Answer 2

you cannot echo $q['user'] because it is an array. Use
`print_r($q['user']); exit;
and you can pass this to your view page by
`$this->load->view('yourViewPage',$q);
