[eluser]GonzaFY[/eluser]
THE SOLUTION IS AT THE END!
I am working in a function to get online users but I am having troubles making the query..
Code:
public function Estado($usuario)
{
// I get the last sessions and check if is my $usuario's sessions.
$funcion = $this->CI->db->where('user_data', $usuario)
->where('last_activity >', time()-500)
->order_by('last_activity', 'desc')
->get('ci_sessions');
// If there is a result
if($funcion->num_rows() == 1)
{
// We return user's data
return $funcion->row();
}
}
The problem is that I need check if the username stored in the user_data(serialized) is the same as the user that I am checking if is online.
If you don't understand me my user_data says:
Code:
a:7:{s:9:"user_data";s:0:"";s:2:"id";s:1:"1";s:7:"usuario";s:7:"gonzafy";s:6:"nombre";s:7:"Gonzalo";s:8:"apellido";s:16:"Fernandez";s:5:"rango";s:1:"2";s:8:"conexion";b:1;}
Then I need do:
Code:
// CHECK user_data[usuario] ..
$funcion = $this->CI->db->where('user_data[usuario]', $usuario)
->where('last_activity >', time()-500)
->order_by('last_activity', 'desc')
->get('ci_sessions');
Do you understand me?
I don't wanna use db->like('user_data', $usuario) because if two users have similar names like: Gonza and GonzaFY, when I am checking Gonza's connection I can get GonzaFY too so will cause troubles..
Thanks..
SOLUTION
I am so stupid... I only needed to request the last sessions and then check if those has userdata, if it has the user is connected so I only need get the username..
Code:
public function Todos()
{
$data = array();
$consulta = $this->CI->db
->where('last_activity >', time()-300)
->order_by('last_activity', 'desc')
->get('ci_sessions');
foreach($consulta->result() as $row)
{
$desencriptar = unserialize($row->user_data);
if(isSet($desencriptar['usuario']))
{
$data[] = $row;
}
}
return $data;
}
and then I call it (I am trying from my controller)
Code:
function conectados()
{
$data = $this->miembros->Todos();
if(!$data == '')
{
foreach($data as $result)
{
$columna = unserialize($result->user_data);
echo $columna['usuario'] . '<br />';
}
}
else {
echo 'No hay ningun usuario online';
}
}
