Body
I have a registration form. Here I'm able to check duplicate email by my custom is unique call back function (Don't try to use is_unique). But it doesn't returns anything. Here is my code. Controller - <pre><code>public function add_member () { $this->load->library('form_validation'); $post_email = $this->input->post('email_id'); $this->form_validation->set_rules('email_id', 'Email ID/ Username', 'required|trim|xss_clean|valid_email|callback_check_duplicate_email[' . $post_email . ']'); $this->form_validation->set_rules('password', 'Your password', 'required|min_length[5]|max_length[12]|matches[confirm_password'); $this->form_validation->set_rules('confirm_password', 'Password Confirmation', 'required'); $this->form_validation->set_message('check_duplicate_email', 'This email is already exist. Please write a new email.'); if ($this->form_validation->run() == FALSE) { // validation failed then do that $this->load->view('member/reg_form'); } else { $data['email_id'] = $post_email; $data['password'] = MD5($this->input->post('password')); $insert = $this->Model_member->insert_data_to_db($data); if ($insert) { $success = "Wao ! You are successfully added to our community."; $this->session->set_flashdata('message_success', $success); $this->load->view('member/success_page'); } else { $error = "Hey this email is already exists in our community."; $this->session->set_flashdata('message_error', $error); $this->load->view('member/reg_form'); } } } // My callback function public function check_duplicate_email($post_email) { return $this->Model_member->checkDuplicateEmail($post_email); } </code></pre> Model - <pre><code> //for checking email existance public function checkDuplicateEmail($post_email) { $this->db->where('email_id', $email_id); $query = $this->db->get('my_registration_table'); $count_row = $query->num_rows(); if ($count_row > 0) { return TRUE; } else { return FALSE; } } // insert data to DB public function insert_data_to_db($data) { return $this->db->insert('my_registration_table', $data); } </code></pre> When I try to submit form with email which is already exists. This function doesn't stop me and doesn't show the validation error message. Would anyone here to see what's the problem? Waiting for your help.

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.
