function success() {
$username = $this->input->post('username');
$password = $this->input->post('password');
$errorMsg ="";
$queryResult = $this->logins->validate($username,$password);
if($queryResult == TRUE) {
redirect ('home');
}
else {
$errorMsg ="Invalid Username or Password";
$this->load->view('login',$errorMsg);
}
}
}
view:- login.php
<script type="text/javascript">
function validatelogin(){
var x=document.forms["login"]["username"].value;
var y=document.forms["login"]["passwrd"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;
}

Answer 1

You aren't loading class "logins"
$this->load->library('Logins');

Answer 2

Try like this in your model
public function __construct() {
// Connecting Database
parent::__construct();
$this->load->database();
}

Answer 3

Please Add your model Class name into config\autoload.php file
$autoload['model'] = array('logins');
Its working fine for me,Please try it.

Answer 4

Load the model named Logins before you use it
$this->load->model('logins', '', TRUE);
or in autoload.php
