CODEIGNITER function can echo but can't return

I have this code in my model file

function exist_kode($kode = 1)        
{
     $get = $this->db->query("SELECT * FROM perkiraan WHERE kode_perk='$kode'");

     if($get->num_rows() == 0)
     {
        return $kode;
     }
     else
     {
        $this->exist_kode((int)$kode+1);
     }
}

This function is not return some values when I use. But if I change return to echo, it will write the value I hope.

How can i solve this?

Solution

  • Return in your else statement as well:

    return $this->exist_kode((int)$kode+1);
