        parent::__construct();
        $this->load->model('Mod_saloon');
        $this->load->helper(array('form', 'url'));
        $this->load->library(array('session', 'form_validation', 'email')); 
        $this->load->helper('url');
    }
    public function index()
    {
        $this->load->view('login');
    }
    public function show_signup()
    {
        $this->load->view('signup');
    }
    public function signup()
    {
        $config = array(
        array(
                'field' => 'name',
                'label' => 'Username',
                'rules' => 'required|min_length[5]|max_length[12]|is_unique[signup.name]'
        ),
        array(
                'field' => 'password',
                'label' => 'Password',
                'rules' => 'required',
                'errors' => array(
                        'required' => 'You must provide a %s.',
                ),
        ),
        array(
                'field' => 'cpassword',
                'label' => 'Password Confirmation',

                'rules' => 'required|valid_email|is_unique[signup.email]'
        )
);

$this->form_validation->set_rules($config);

        $this->form_validation->set_rules(
        'name', 'Username',
        'required|min_length[5]|max_length[12]|is_unique[signup.name]',
        array(
            'required'      => 'You have not provided %s.',
            'is_unique'     => 'This %s already exists.'
        )
        );
        $this->form_validation->set_rules('password', 'Password', 'required');
        $this->form_validation->set_rules('cpassword', 'Password Confirmation', 'required|matches[password]');
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[signup.email]');
        if ($this->form_validation->run() == FALSE) 
        {
            echo "<script>alert('Validation Error');</script>";
            $this->load->view('signup');
        } 
        else 
        {
            $name = NULL;
            $role=NULL;
            $email=NULL;
            $password=NULL;
            $cpassword=NULL;

            extract($_POST);

            $signup['$name'] = $name;
            $signup['$role'] = $role;
            $signup['$email'] = $email;
            $signup['$password'] = $password;
            $signup['$cpassword'] = $cpassword;

            $this->Mod_saloon->new_signup($signup);

            $this->load->view('signup');
        }


    }
}

This is my View

<form action="signup" method="post">
            <div class="form-group has-feedback">
                <input type="text" class="form-control" name="name" placeholder="Name">
                <span class="glyphicon glyphicon-user form-control-feedback"></span>
            </div>
            <select class="form-control" name="role">
                <option disabled selected value> --Select the Role-- </option>
                <option value="admin">Admin</option>
                <option value="user">User</option>
            </select>
            <div class="form-group has-feedback">
                <input type="email" class="form-control" name="email" placeholder="Email">

            </div>
            <div class="gap"></div>
            <button type="submit" class="btn btn-primary btn-block btn-flat centered" style="width:35%;">Create User</button>
        </form>

Answer 1

I think that your problem is not that your form validation is not working...in your controller your "signup" function does not seem to run anywhere.You need to check your routes and in the function that is used to run your link you need to call

$this->signup

You also need to call it on form submission so in your view the submit button must have a name and a value(eg: name="create_user",value="something") signup you should have

If ($this->input->post('create_user')){do the form validation thing}

Answer 2

change action in form like

<form action="<?php echo base_url()?>index.php/Login/signup" method="post">

and there is no need to set rules multiple times. either you can use array method, or set rules individually

Answer 3

Your code needs lots of correction

1. Form Tag

Your Need to change the form tag first:

<form action="<?= base_url('login/signup') ?>" method="post">

2. Put Your Config array inside config folder. Add Your Config array in form_validation.php add below code in this file.

application/config/form_validation.php

$config = array(
    'signup_validation' => array(
        array(
                'field' => 'name',
                'label' => 'Username',
                'rules' => 'required|min_length[5]|max_length[12]|is_unique[signup.name]'
        ),
        array(
                'field' => 'password',
                'label' => 'Password',
                'rules' => 'required',
                'errors' => array(
                        'required' => 'You must provide a %s.',
                ),
        ),
        array(
                'field' => 'cpassword',
                'label' => 'Password Confirmation',
                'rules' => 'required|matches[password]'
        ),
        array(
                'field' => 'email',
                'label' => 'Email',
                'rules' => 'required|valid_email|is_unique[signup.email]'
        )
    )
    );

3. Your Controller function

Here is the code of your controller function

public function signup()
{

    if ($this->form_validation->run('signup_validation') == TRUE) {

        // Your sign up the code if validation is true. 

    } else {
        // load the view 


        //User validation_errors(); to show all your validation error at view
    }
}
