I am using codeigniter to get a single result from the db, like this:
$user = $this->db->query("SELECT * FROM users LIMIT 1");
I am then getting the returned object and looping trough it, this way:
foreach ($user->result() as $row) { ... }
As you can imagine, there is not point in using the loop, since there is only one result. Is there a way to get users parameters without looping? Something among this line:
echo $user['name'];
Thanks in advance.
$user = $this->db->query("SELECT * FROM users LIMIT 1")->row();
for having it as an object ( echo $user->name;)
$user = $this->db->query("SELECT * FROM users LIMIT 1")->row_array();
for having is as an array ( echo $user['name']; );
$user = $this->db->limit(1)->get('users')->row(); //or ->row_array();
using AR;
$row = $user->first_row();
to get the first row out of a result set ($this->db->result()), as an object (default);
$row = $user->first_row('array');
to get the first row out of a result set, as an array;
$row = $user->row_array(1);
to return a specific row (first, in this case. Just pass the <N> of the row). Works also for $user->row(1);
It would be:
$user = $this->db->query("SELECT * FROM users LIMIT 1")->row_array();
More details here: http://ellislab.com/codeigniter/user-guide/database/results.html
do something like this
//in the model
$query = $this->db->query("your query");
$row = $query->row();
if (isset($row))
return $row;
}else{
return false;
}
then echo your results like this
echo $row->username;
if you want to pass it to a view
//in the controller
$this->load->model('somemodel');
$hm=$this->somemodel->somemethod();
$data['query']=$hm;
$this->load->view('path/to/view',$data);
Then echo the same way
echo $row->username;
Suppose for example your model function is like this.......
public function get_users()
{
$query = "Select * from users limit 1";
$res=$this->db->query($query);
if($res->num_rows()>0){
return $res->result("array");
}
return array();
}
Suppose you are calling this model in your controller function like this
$users = $this->model_file->get_users();
then you can echo like this echo $users[0]['user_name'];
You can also pass a string to result() which represents a class to instantiate for each result object (note: this class must be loaded)
