<?php
class Admin extends CI_Controller {

    public function index() {

        $this->load->view('admin');
    }

    public function create_user() {

        $this->load->model('user_model');
        echo $this->user_model->create($_POST['email'], $_POST['password']);
    }

    public function delete_user($user_id) {

        $this->load->model('user_model');
        $this->user_model->delete($user_id);
    }
}

models/user_model.php

<?php
class User_model extends CI_Model {

    public function __construct() {

        parent::__construct();
    }

    public function create($email, $password) {

        return $this->db->insert('user', [
            'email' => $email,
            'password' => $password
        ]);
    }

    public function delete($user_id) {

        $this->db->where(['user_id' => $user_id]);
        return $this->db->delete('user');
    }
}

views/admin.php

    Email: <input type="email" name="email" /><br />
    Password: <input type="password" name="password" /><br />
    <input type="submit" />
</form>

Answer 1

In your model you have [] brackets in the insert you can not do it that way. Also when insert you do not need return.

And in your form action try replacing site url with perferd base_url()

Make sure url and form helpers are auto loaded. please read user guide http://www.codeigniter.com/userguide3/index.html

echo $this->user_model->create($_POST['email'], $_POST['password']); not good try var dumping post, and also look into form validation codeigniter. I think because you are not running form validation in controller.

Codeigniter 3 is out on github BCIT. https://github.com/bcit-ci/CodeIgniter

<?php

class User_model extends CI_Model {

public function __construct() {

    parent::__construct();
}

public function create($email, $password) {

     $email = $this->input->post('email');
     $password = $this->input->post('password');

     $data = array(
      'email' => $email
      'password' => $password
     );

     $this->db->insert_id();
     $this->db->insert('user', $data);

}

public function delete($user_id) {
    $this->db->where('user_id',  $user_id);
    $this->db->delete('user');
}
}
