If ip address is displayed in form action or url
http://::1/yourproject/http://127.0.0.1/yourproject/
Chances are you have left the base url blank
/*
|--------------------------------------------------------------------------
| Base Site URL
|--------------------------------------------------------------------------
|
| URL to your CodeIgniter root. Typically this will be your base URL,
| WITH a trailing slash:
|
| http://example.com/
|
| WARNING: You MUST set this value!
|
| If it is not set, then CodeIgniter will try guess the protocol and path
| your installation, but due to security concerns the hostname will be set
| to $_SERVER['SERVER_ADDR'] if available, or localhost otherwise.
| The auto-detection mechanism exists only for convenience during
| development and MUST NOT be used in production!
|
| If you need to allow multiple domains, remember that this file is still
| a PHP script and you can easily do that on your own.
|
*/
$config['base_url'] = '';
Now days in latest versions of codeIgniter it is not recommend that you leave your base_url blank.
$config['base_url'] = 'http://localhost/yourproject/';$config['base_url'] = 'http://www.example.com/';
And is always good to end url with /
You may need to create routes for your form here
application > config > routes.php
CodeIgniter 3: Routing
CodeIgniter 2: Routing
Update:
With CodeIgniter 3 + versions:
When you create a file remember you will have to have first letter ONLY upper case on file names and classes.
What will happen sometimes is that it all may well work in a localhost environment with lower case but when you go to a live server some times will throw errors or not submit forms correct etc.
Example: From Controllers This also applies to Models
This is valid
File name: Verifylogin.php
<?php
class Verifylogin extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
}
}
This is valid
File name: Verify_login.php
<?php
class Verify_login extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
}
}
This is not valid
File name: verifylogin.php
class verifylogin extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
}
}
This is not valid
File name: Verify_Login.php
class Verify_Login extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
}
}
