IP address is showing in form action with CodeIgniter http://::1/codeigniter/ in html sourcecode

Question

I have the CI script installed on Xampp. Currently I am working on forms and when I click on submit on html, it does nothing.

I tried

echo form_open('verifylogin');
echo form_open();

It show on sourcecode as

<form action="http://::1/codeigniter/verifylogin">
<form action="http://::1/codeigniter/">

respectively.

I don't understand what this "http://::1/" is and how to get rid of it?

Answer 1

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

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() {

    }

}

Answer 2

Go to application/config/config.php set base_url

$config['base_url'] = 'http://localhost/example/';

And refresh your application

Then ::1 error should be gone.

Answer 3

Go to System/core/Config.php

Set config in line 84

public function __construct()
    {
        $this->config =& get_config();

    // Set the base_url automatically if none was provided
    if (empty($this->config['base_url']))
    {
        // The regular expression is only a basic validation for a valid "Host" header.
        // It's not exhaustive, only checks for valid characters.
        if (isset($_SERVER['HTTP_HOST']) && preg_match('/^((\[[0-9a-f:]+\])|(\d{1,3}(\.\d{1,3}){3})|[a-z0-9\-\.]+)(:\d+)?$/i', $_SERVER['HTTP_HOST']))
        {
            $base_url = (is_https() ? 'https' : 'http').'://'.$_SERVER['HTTP_HOST']
                .substr($_SERVER['SCRIPT_NAME'], 0, strpos($_SERVER['SCRIPT_NAME'], basename($_SERVER['SCRIPT_FILENAME'])));
        }
        else
        {
            $base_url = 'http://localhost/';
        }

        $this->set_item('base_url', $base_url);
    }


    log_message('info', 'Config Class Initialized');
}

Answer 4

Remove / from url

Previous :

<li><a href="/<?=site_url('contacts/create')?>">New Contact</a></li>

After :

<li><a href="<?=site_url('contacts/create')?>">New Contact</a></li>

Answer 5

I solved this problem by removing the "/" in the redirect

Before:

header("Location: /index.php?error=TRUE")

After:

header("Location: index.php?error=TRUE")
