Form Submission and URI rewriting - php

Question

I have a fairly standard CI3 site up and running. I have created my own base controller, called MY_Controller, and all my page controllers extend this.
MY_Controller.php
public function __construct() {
parent::__construct();
}
/**
* Display the view. This function wraps up all the teplates,
* sets the page title, adds all the requested Javascript and CSS,
* and passes along any data.
* #param string $view The name of the content view to display
* #param array $data (Optional) ÏAn array of any data to pass along
*/
protected function showView($view, $data = null) {
if ($data === null) {
$data = array();
}
// call all the template pieces
$this->load->view('header', $data);
$this->load->view('mainNav', $data);
$this->load->view($view, $data);
$this->load->view('footer', $data);
}
Each page controller calls $this->showView($viewName, $data); when it's ready to display results or whatever.
I have a form located on my login controller, Login.php.
Login.php has a method called "submit".
public function submit() {
$cfg = array(
array(
'field' => 'username',
'label' => 'Username',
'rules' => 'required|trim|alpha_numeric|xss_clean|min_length[3]|max_length[50]'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'required|trim|alpha_numeric|xss_clean|min_length[3]|max_length[50]'
)
);
if ($this->form_validation->set_rules($cfg) === false) {
$this->showView("login");
} else {
$data = array(
'password' => $this->input->post('password')
);
if (filter_var($this->input->post('username'), FILTER_VALIDATE_EMAIL) === false) {
$data['username'] = $this->input->post('username');
} else {
$data['email'] = $this->input->post('username');
}
$user = $this->User->getUserFromLogin($data);
if ($user !== false) {
$sessionData = array(
'userName' => $user->userName,
'email' => $user->email,
'authToken' => $user->authToken,
'lastSeen' => date("Y-m-d")
);
// Add user data to session
$this->session->set_userdata('userLoggedIn', true);
$this->session->set_userdata('userData', $sessionData);
$this->showView("home");
} else {
$data = array(
'error_message' => 'User could not be loaded.',
);
$this->showView("login", $data);
}
}
}
My Login view, login.php
<div class="wrapper style1">
<article id="work">
<header>
<h2>Login!</h2>
<?=validation_errors();?>
</header>
<div class="container 50%">
<section>
<form method="post" action="login/submit">
<div>
<div class="row">
<div class="6u">
<input type="text" name="username" id="username" placeholder="username or email" value="<?=set_value('username');?>" />
</div>
<div class="6u">
<input type="password" name="password" id="password" placeholder="password" />
</div>
</div>
<div class="row">
<div class="12u">
<ul class="actions">
<li>
<input type="submit" value="Sign in!" />
</li>
</ul>
</div>
</div>
</div>
</form>
<footer>
<div>...or sign in with Facebook!</div>
<fb:login-button scope="public_profile,email" onlogin="checkLoginState();"></fb:login-button>
</footer>
</section>
</div>
</article>
</div>
Upon successful submission of the form, I'm expecting it to redirect me to home, which it is, however, the URI is localhost/login/submit instead of localhost/home.
Likewise with my logout controller, upon logout, it navigates to the URI localhost/logout/logout, which generates a 404.
I can't figure out why it doesn't redirect to the controller I've specified in the showView() method.
I'm not using any custom routing tricks.

Answer 1

The method showView simply loads in the values extra templates you want as well as the data you sent. I believe you are looking to do a redirect when you need to move off of pages instead of just rerendering the page the way you are.
redirect($uri = '', $method = 'auto', $code = NULL)
If this doesn't suffice your needs please include you routes and your logout controller to see what's going on in the other scenario you mentioned.

Answer 2

On successful authentication, instead of
$this->showView("home");
you should change that to redirect(),
redirect("controller/method/parameters if any");

Answer 3

there is method call showview(). To load view you have to use
$this->load->view("login");
as well as redirect should be
redirect('controller_name/method_name');
