access variables from other function within same class?

[eluser]Kristof[/eluser]

Code:

class M_airports extends model {    
    function addAirport() {
         $data = array(
            'airportname' => $this->input->post('airportname'),
            'airportwebsite' => $this->input->post('airportwebsite'),
            'airportphone' => $this->input->post('airportphone'),            
        );
        $this->db->insert('aiports', $data);
        $ID = $this->db->insert_id();    
    }
    function addAirportpics($filename,$filelocation) {      
        $data = array(
            'AirportpicsAirportid' => $ID,
            'AirportpicsFolder' => $filelocation,
            'AirportpicsFilename' => $filename
        );
        $this->db->insert('airportpics', $data);    
    }
}

I need the $ID in the addAirportpics function but i don't know how to get to it. Could someone please help me out with this? Thanks in advance

You need to use a class variable:

Code:

class M_airports extends model {    
    var $id;
    
     function addAirport() {
         $data = array(
            'airportname' => $this->input->post('airportname'),
            'airportwebsite' => $this->input->post('airportwebsite'),
            'airportphone' => $this->input->post('airportphone'),            
        );
        $this->db->insert('aiports', $data);
        $this->id = $this->db->insert_id();    
    }
    function addAirportpics($filename,$filelocation) {      
        $data = array(
            'AirportpicsAirportid' => $this->id,
            'AirportpicsFolder' => $filelocation,
            'AirportpicsFilename' => $filename
        );
        $this->db->insert('airportpics', $data);    
    }
}

ow that's easy thank you for your help !!!!!

That's a bit messy though, as depending on when addAirportpics is called, all sorts of funny behaviour could result.

Perhaps return $ID from addAirport, and then pass it back into addAirportpics as a function variable. This makes the function more portable, and also you can do some error checking in the controlling function before calling it.

I have the same issue and I tried the way you mentioned but

Code:

echo $this->id

is not showing anything
