Body
<pre><code><? if ( ! defined('BASEPATH')) exit(); class Registration extends CI_Controller { public function __construct() { parent::__construct(); $this->load->model('registration_model'); } public function index() { $this->load->library('form_validation'); $this->form_validation->set_rules('email', 'E-mail', 'trim|required|valid_email|callback_email_available'); if($this->form_validation->run() == FALSE) { $this->load->view('registration'); } else { $this->registration_model->add_user(); } } # Check E-mail public function email_available($email) { $this->db->select('email'); $this->db->where('email', $email); $query = $this->db->get('users'); $result = $query->row(); if(!empty($result)) { $this->form_validation->set_message('email_available', 'This e-mail belongs to another user.'); return FALSE; } else { return TRUE; } } } ?> </code></pre> I have a registration form with Form Validation. And I have a callback function to validate email uniqueness. All code works fine, but I can directly access to callback function with errors examle.com/registration/email_available <pre><code>A PHP Error was encountered Severity: Warning Message: Missing argument 1 for Registration::email_available() Filename: controllers/registration.php A PHP Error was encountered Severity: Notice Message: Undefined variable: email Filename: controllers/registration.php </code></pre> How can I deny direct access to callback function?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
