Login Form With Codeigniter

[booxvid]

Here's the snippet code in controller:

 

public function me_login(){

$this->load->view('header');
$this->form_validation->set_rules('username','First Name','required');
$this->form_validation->set_rules('password','Last Name','required');

$this->form_validation->set_error_delimiters('
','');

if($this->form_validation->run()==FALSE){
$this->load->view('view_login');
}
else{

$u= $this->input->post('username');
$p= $this->input->post('password');

$username = trim($u);
$password = trim($p);

//search same info from db
$boolean = $this->blog_model->login($username,$password);


if($boolean){

$userdata = array(
'username' => $username,
'logged_in' => TRUE
);

$this->session->set_userdata($userdata);

echo "";
$this->load->view('view_home',$userdata);

}
else{
echo "";
$this->load->view('view_login');
}
}


}

 

here's my blog_model where my login function located:

public function login($username,$password){
$encode = $this->encrypt->encode($password);
$query = $this->db->get_where('blog_user', array('username' => $username, 'securepass' => $encode));
return $query->result();

}

 

I don't know why my Login function will always be failed.

Foremost, I don't understand your usage with the 'error deliminators' - are you expecting to use newlines?

 

This:

$u= $this->input->post('username');
$p= $this->input->post('password');

$username = trim($u);
$password = trim($p);

 

Can be replaced with:

$this->form_validation->set_rules('username','First Name','required|trim');
$this->form_validation->set_rules('password','Last Name','required|trim');

 

Now, in order to determine why it's failing, I suggest you query for the username that matches the input value and echo out the password in its row AND the hashed POST value. If the two do not match, then you need to figure out where the problem starts.

In addition to Mahngiel's suggestions, in your login function, since you only need to check if the user name is valid or not and not using the data, you can do something like this instead of returning the whole data

 

 

public function login($username,$password){
$encode = $this->encrypt->encode($password);
$query = $this->db->get_where('blog_user', array('username' => $username, 'securepass' => $encode));
if ($query->num_rows() == 1){
  return TRUE;
}else{
  return FALSE;
}

}
