PHP Session MVC using CodeIgniter -

so have been developing simple login , insert data pages using codeigniter, want every user has own data kept in db , every user has own set of-db. focus here session first, because can't session code.

i new php , never use php native 1 before. here controller:

    public function login(){     $this->load->library('session');     $email  = $this->input->post('email');     $password  = $this->input->post('password');         log_message('error','isi email : '.$email);     log_message('error','isi password : '.$password);     $return = $this->welcome_model->checklogin($email, $password);      if($return){     $this->session->set_userdata('email',$email);     $var = $this->session->userdata;     redirect('welcome/masuk');} 

model:

public function checklogin($email, $password) {     $return = $this->db->get_where('login',array('email'=>$email, 'password' => $password));      if($return->result_array() != null){          return true;      }else{           return false;      }  } 

view:

<form action="<?php echo base_url(); ?>welcome/login" method="post">     <input type="email" class="form-control" name="email" placeholder="email">     <input type="password" class="form-control" name="password" placeholder="password">     <button type="submit" class="btn btn-primary btn-block btn-flat">sign in</button>     </form> 

any appreciated! thanks!

alright, think need following points while considering making login page :-

 1. $this->load->library('session');  //try put in autoload.php in application/config.     $autoload['libraries'] = array('session');  2. <form action="<?php echo base_url(); ?>welcome/login" method="post">    can replace in view     <?= form_open() ?>....code....<?= form_close() ?>  3. try use form-validation rules    $this->form_validation->set_rules(         'title',          'title',          'required|min_length[20]'); 

and yes separating users need separate each user on bases of it's unique id,username,usergroup...etc. more importantly codeigniter user-guide , if you've got stuck anywhere we've stackoverflow take care of us, keep updating database structure per requirements.

that's login page per application requirements

public function login()  {     $data = array();     $this->form_validation->set_rules(                                     'username', 'username',                                     'required|min_length[5]'     );     $this->form_validation->set_rules(                                     'password',                                      'password',                                      'trim|required|min_length[6]'     );        if ($this->form_validation->run() == false)     {          $this->template->set('title', 'login');          $this->template->load('main', 'contents' , 'login', $data);     }     else     {         $username = $this->input->post('username');         $password = $this->input->post('password');            if ($this->main_model->resolve_user_login($username, $password))          {             $user_id = $this->main_model->get_user_id_from_username($username);             $user    = $this->main_model->get_user($user_id);                      $this->session->user_id      = (int)$user->id;             $this->session->username     = (string)$user->username;             $this->session->name         = (string)$user->name;             $this->session->password     = (string)$user->password;             $this->session->created_at   = (bool)$user->created_at;             $this->session->blog_id      = (bool)$user->blog_id;                $this->session->logged_in    = (bool)true;             redirect('dashboard');         }          else          {              $this->template->set('title', 'login');              $this->template->load('main', 'contents' , 'login', $data);         }     } }
