call static method from model - El Forum - 08-14-2008

if i had understand the userguide if i want use a methode from model i should
code like this.

Code:
$this->load->model('Commercial', '', TRUE);

        $data['commande'] = $this->Commande->SelectCommande();        

        $data['commercial'] = $this->Commercial->SelectCommercial();

but if i want use a static method in order to not instanciate the object (that is the goal
of a static methoc) ?

apparently the load method use a singleton, it's better than anything, but if i want no instancitiation because of memory cost for example, should i write my controller like this:

Code:
require_once(myclass.php);

$data = myclass::mymethod(parameter);

By the way before write this post i have tried to set the static attribut, and it generate a warning. Normal ?

it quite ugly no ? any answer or solution ?
Thanks

A bunch of code might be helpful for you. Whether i don't know using static variable are good practice or not. Anyway, in my project i use this static variable in some classes inside \application\libraries\

Here is an example class and how to use function.

Code:
class Custom_config extends Controller

{

    function Custom_config()

    {

        //parent::Controller();    //Strictly Prohibited.

    }

    function MemberProfileInfo($MemberId)

    {

        global $Data;

        $query = $this->db->query("SELECT P.*, L.* FROM member_profile P, member_login L WHERE L.mem_id=P.member_id AND P.member_id='$MemberId'");

        if ($query->num_rows() > 0)

        {

            $row = $query->row();

            $Data['MemberFirstName']=$row->mem_first_name;

            $Data['MemberLastName']=$row->mem_last_name;

            $Data['MemberEmail']=$row->mem_email;

        }

    }

}

Now i in my config\autoload.php i load this class. And call this function frequently from many controllers as

Code:
// Inside method of a class

static $Data;

Custom_config::MemberProfileInfo($MemberId);

echo $Data['MemberEmail']; // i get member email instantly.

however, i am not sure this is a good practice or not. So i also like to know about it.

Thanks for your proposition, i was wondering if i would not use a librairy to use static method too.

I 'm not sure that ur obliged to imply inheritance from controller if u don't use parent::Controller ... Wink

i will try your proposition, and compare with others

thx

If you want to use a static method, either don't use the CI loader, or make a static class a helper. Unlike Models and Libraries, the CI loader doesn't instantiate helpers - because it doesn't expect them to be classes. All it does is include them. There is nothing stopping you from putting a class with static methods in the helpers directory though.
