Codeigniter Identify Every 3rd user Registration referral - php

Question

I'm currently developing an MLM Website using Codeigniter Framework.
And I am working on registration now. I can register successful with referral user
The problem is every 3 registration using my referral username/id i need to run another query because in 1st and 2nd referral I earned 200. and in 3rd user will refer i will only earn 100.
How can I do that in Codeigniter? anyone done this? please help

Answer 1

Let me throw some light on this
So lets say you make a post for every registration, the post goes to a class names registration and a register method, and the referral id runs as a session (refID). Also, you have a registration model, this is what you should likely do:
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
}
}
}
Now this is how your registration model will look like this
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();
}
}
I hope this explains what you really wants, and helps you. If you find any difficulty, kindly comment and lets sort it out.
