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

<form action="http://::1/codeignITer/verifyLOGin">
<form action="http://::1/codeigniter/">

如果ip地址显示在表单action或url中

> http：// :: 1 / yourPRoject /
> http://127.0.0.1/yourproject/

有机会将基本网址留空

/*
|--------------------------------------------------------------------------
| 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

$config['base_url'] = '';

现在,在最新版本的codeIgniter中,不建议您将base_url留空.

> $config [‘base_url’] =’http：// localhost / yourproject /’;
> $config [‘base_url’] =’http://www.example.com/’;

并且总是好的结束url与/

您可能需要在此处为​​您的表单创建路线

application > config > routes.PHP

CodeIgniter 3：Routing

CodeIgniter 2：Routing

更新：

当您创建文件时,您必须在文件名和类上具有第一个字母大写.

有时候会发生这样的情况,所有这些都可能在本地主机环境中工作较少,但是当您访问实时服务器时,会发生错误或不提交表单正确等.

示例：从Controllers这也适用于Models

这是有效的

文件名：Verifylogin.PHP

<?PHP

class Verifylogin extends CI_Controller {

    public function __construct() {
       parent::__construct();
    }

    public function index() {

    }

}

这是有效的

文件名：Verify_login.PHP

<?PHP

class Verify_login extends CI_Controller {

    public function __construct() {
       parent::__construct();
    }

    public function index() {

    }

}

这是无效的

文件名：verifylogin.PHP

class verifylogin extends CI_Controller {

    public function __construct() {
       parent::__construct();
    }

    public function index() {

    }

}

这是无效的

文件名：Verify_Login.PHP

class Verify_Login extends CI_Controller {

    public function __construct() {
       parent::__construct();
    }

    public function index() {
