Using POST data after validating using CodeIgniter

codeigniter, php, post, registration

Solution

The CodeIgniter input class allows you to get the POST data after it has been filtered by the form validation library. In your controller you would do the following:

$username = $this->input->post('username');
$email = $this->input->post('email');
$password = $this->input->post('password');

Problem

I have a signup form where I'm validating user input. Here's my controller: ``` <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Register extends CI_Controller { public function index() { $this->load->model('Users_model'); $this->load->helper('form'); $this->load->library('form_validation'); $data['page_title'] = 'Register'; $this->load->view('header', $data); // Set form validation rules $this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[16]|xss_clean|callback_username_check'); $this->form_validation->set_rules('email', 'Email', 'trim|required|min_length[5]|max_length[64]|valid_email|callback_email_check'); $this->form_validation->set_rules('password', 'Password', 'required'); $this->form_validation->set_error_delimiters('<span class="error">', '</span>'); if ($this->form_validation->run() == FALSE) { $this->load->view('register', $data); } else { // Add the user to the database $this->Users_model->add_user(); $this->load->view('register_success', $data); } $this->load->view('footer', $data); } /* Functions to check username and email */ } /* End of file register.php */ /* Location: ./application/controllers/register.php */ ``` The problem is with this line: `$this->Users_model->add_user();`. I want to pass the username, email and password to my Users model to add the user to my database, but I'm not sure how I can get the POST data into that method. Normally I'd use `$_POST['username']` etc but CodeIgniter has run some functions on the input values (`trim()`, `xss_clean` etc). How can I get these values and pass them into my `add_user()` method?
