<legend>Student Login</legend>
<div class="form-group">
<div class="col-lg-6 col-md-6 col-xs-10">
<?php echo form_input(['name'=>'rno','class'=>'form-control','placeholder'=>'Roll Number'])?>
</div>
</div>
<div class="form-group">

public function index()
{
$this->load->view('user/user_login_view');
}
public function login()
{
echo "User login function";
}
}
?>
but it's given me 404 error.however i have both files
and when I m going through url(http://localhost:8090/project/user_login_controller/login) :then its working. and i have loaded all the necessary helpers.
$autoload['helper'] = array('url','form');
what to do now?

Answer 1

You should set config['base_url'] in application/config/config.php
$config['base_url'] = 'http://localhost:8090/project/';
as form_open consider url to be set to http://localhost:80/project/ or http://[::1]/project/ if you didn't set config['base_url']

Answer 2

Follow below steps and it will sort-out the problem,
1. View
when you opening a form tag, if you want to add several attributes, use this method.
<?php
$attributes = array('class' => 'form-horizontal', 'id' => 'userloginform');
echo form_open('user_login_controller/login', $attributes);
?>
It's clean and error less.
2. Config.php
Go to application/config/config.php file, and set
$config['base_url'] = 'http://localhost:8090/your_project_folder_name/';
3. routes.php
Go to application/config/routes.php file, and set
$route['user_login_controller/(:any)'] = "user_login_controller/$1";
$route['user_login_controller'] = "user_login_controller";
This will work. Try it and let me know.
