How to integrate auto login SMF forum in CakePHP 2.x?

I am going to integrate smf forum v.2.0.9 in my cakephp 2.x. I am using SSI.php

I have a users table in cakephp and another table name smf_members. I have successfully registered by using CakePhp code.

I have also successfully login in forum but page not redirected to my login page.

My code:

login.ctp

$_SESSION['login_url']='http://mydomainname.com/login';
$_SESSION['logout_url']='http://mydomainname.com/logout';

<form accept-charset="UTF-8" action="http://mydomainname.com/forum/index.php?action=login2" method="post">
      <input type="text" name="user" id="user" placeholder="Emailid" />
      <input type="password" id="passwrd" name="passwrd" placeholder="Password" />
      <input type="password" id="passwrd" name="passwrd" placeholder="Password" />
</form>

Above code successfully login. But page not redirect it stay in the forum index.php page. After login I need redirect page to http://mydomainname.com/login

This file is working if i am writing in core

Code:

<?php
include('forum/SSI.php');
$_SESSION['login_url']='http://mydomainname.com/login';
$_SESSION['logout_url']='http://mydomainname.com/logout';

/*echo "<pre>";
print_r($_SESSION); //exit;
echo "</pre>"; */
ssi_login();
?>

Please share your knowledge.

Thanks ChatFun

Solution

After lots of research finally i got one solution.

I have created external php file within webroot folder

i write following code in external_login.php-

<?php
if(isset($_REQUEST['login'])){
session_start();
//include('forum/SSI.php');
?>

<body>
<div style="display:block; position:relative">
<div style="position:absolute; left:-200px;">
<form accept-charset="UTF-8" action="<?php echo 'forum/index.php?action=login2';?>" method="post" name="smf_login_frm" id="smf_login_frm">
<input type="text" name="user" id="user" width="1" style="width:1px;" value="<?php echo $_SESSION['Auth']['User']['email'];?>" />
<input type="password" id="passwrd" name="passwrd" style="width:1px;" value="<?php echo $_SESSION['passwd'];?>" />
</form>
</div>
</div>
<script>
setTimeout(function(){ validateSubscription(); }, 1000);

function validateSubscription() {
        //document.smf_login_frm.submit();
        document.getElementById("smf_login_frm").submit();
        return false;
}
</script>
</body>
</html>
<?php
}else if(isset($_REQUEST['logout'])){
include('forum/SSI.php');

global $context, $txt, $scripturl;
    $redirect_to = 'http://'.$_SERVER['HTTP_HOST'].'/login';
    $_SESSION['logout_url'] = $redirect_to;

    header('location:'.$scripturl . '?action=logout;' . $context['session_var'] . '=' . $context['session_id']);
    //$link = '<a href="' . $scripturl . '?action=logout;' . $context['session_var'] . '=' . $context['session_id'] . '">' . $txt['logout'] . '</a>';
    //echo $link;


}else{

}?>

First i have successfully login cakephp. then i will redirect to external_login.php. There i am getting my cakephp login session. So i assign username and password then again i will redirect to smf forum login page. After successfully smf forum login page again redirected to Cakephp home page if i both are login successfully.

public function login() {
        if ($this->Session->read('Auth.User')) {
            $this->redirect($this->webroot);
        } else {
            $this->layout = 'login';
            if ($this->request->is('post')) {
                $data=$this->request->data;
                $this->Session->write('passwd',$data['User']['password']);
                if (!$this->Auth->login()) {
                    $this->Session->setFlash(__('Your Email or Password was incorrect.'), 'error_message');
                }
            }
            if ($this->Session->read('Auth.User')) {
                $this->redirect($this->webroot . 'external_login.php?login&hash_token='.md5(time()));
                exit;
                /*if ($this->Session->read('Auth.User.type') == 1) {
                    $this->redirect($this->webroot . 'users/index');
                    exit;
                }
                if ($this->Session->read('Auth.User.type') == 2 || $this->Session->read('Auth.User.type') == 3) {
                    $this->redirect($this->webroot . 'myprofile');
                    exit;
                }*/
            }
        }
    }
