I am creating a function to obtain interpreter data based on the interpreter ID. This is the function that I created:

interprete_model.php

Models

public function interpreteID($id)
{
        //consultar los datos
        $this->db->select('*');

        $this->db->where('id_interprete', $id);

        $this->db->from('tbl_interpretes');       

        $query = $this->db->get();

        if($query->num_rows() > 0 )
        {
            return $query->result();
        }
        else
        {
            return false;
        }   


}

I'm calling this method in my interpreter / profile.php file:

Controller

public function index()
{
        $id = $this->session->userdata('user_id');
        echo "User ID ".$id;

        $query = $this->interprete_model->interpreteID($this->session->userdata('user_id'));

        echo "consultar los datos: ".$query;
        //vista
        $this->load->view('perfil_view',$data);
}

When I do this I get an error saying:

missing the data on the web.

Could someone please tell me why he is doing this?

What happens is that you are printing an array like String, in your model you are returning return $query->result(); that returns an array, if you want to print this array you could use print_r ()

Your controller is like this:

public function index()
{
        $id = $this->session->userdata('user_id');
        echo "User ID ".$id;

        $query = $this->interprete_model->interpreteID($this->session->userdata('user_id'));

        echo "consultar los datos: ".$query; // El error esta aquí
        //vista
        $this->load->view('perfil_view',$data);
}

You could do the following:

public function index()
{
        $id = $this->session->userdata('user_id');
        echo "User ID ".$id;

        $query = $this->interprete_model->interpreteID($this->session->userdata('user_id'));

        echo "consultar los datos: "; 
        print_r($query); // Usar print_r() para imprimir el arreglo;
        //vista
        $this->load->view('perfil_view',$data);
}
