Codeigniter識別每第三個用戶注冊推薦人

Question

我目前正在使用Codeigniter Framework開發一個MLM網站。

我現在正在注冊。 我可以向推薦用戶注冊成功

問題是每3個使用我的推薦用戶名/ ID進行注冊，我都需要運行另一個查詢，因為在第一和第二推薦中我賺了200。在第三用戶中，我只能賺100。

如何在Codeigniter中做到這一點？ 有人這樣做嗎？ 請幫忙

讓我對此進行一些說明。因此，可以說您為每個注冊創建了一個帖子，該帖子轉到了一個類名注冊和一個register方法，並且引用id作為會話（refID）運行。 另外，您有一個注冊模型，這可能是您應該做的：

class registration extends CI_Controller{
    function __construct(){
        parent::__construct();
        $this->load->model('registration_model');
    }

    //ensue to check for the existence of the refID session before processing
    function register(){

        if($_POST){
            //first run form validation
            //you should have auto loaded the form_validation library
            //and created a rules function that carries the form rules
            $rules = $this->rules();
            $this->form_validation->set_rules($rules);

            if($this->form_validation->run() == FALSE){
                //load view here
            }else{
                //first, get post data
                //then get the number of registration done by user using the refID
                //if registration is greater than 2, set earnings to 100
                //set earnings to 200
                //then proceed to insert registration and do something else



                //get post data, assumed post data
                $name = $this->input->post('name');
                $email = $this->input->post('email');

                //get number of registrations
                $numOfRegs = $this->registration_model->getRegByRefID();

                //set the earnings from the number of registrations
                $earning = $numOfRegs < 3 ? 200 : 100;
                //please note that the for $numOfRegs = 4, $earnings will be 100, as this was not specified in the question

                //at this point, you have set the earnings, you can proceed to do whatever you wish to do, perhaps insert the records

                //please note that this code block just explains what you can likely do after setting the earnings
                $insert = array(
                    "name" => $name,
                    "email" => $email,
                    "earning" => $earning
                );
                $this->registration_model->insert($array);
                // then do anything else
            }
        }else{
            //load view here
        }
    }
}

現在這就是您的注冊模型的樣子

class Registration_model extends CI_Model{

    function __construct(){
        parent::__construct();
    }

    function getRegByRefID(){
        $refID = $this->session->refID;
        return $this->db->get_where('mydb', array("refID" => $refID))->num_rows();
    }


}
