Can't write data into database

You are not getting the results from your query. Only the results object. The below should work.

Code:

$USR_ID = $this->db->query("select USR_ID from users where USR_Nick='".$this->input->post('username')."'")->row()->USR_ID;
          
        
          
$ADDR_ID = $this->db->query("select ADDR_ID from address where ADDR_StreetName='".$this->input->post('ulica')."'")->row()->ADDR_ID;
