Our customers uses this registration page to keep their information in our database. Once registered, this information will be displayed in a checkout page for a speedy process. This post covers the customer registration function, login and logout function.

All the fields are required and rules are set in function registration.
function registration
This function sets the recaptcha as we did in the previous post, then sets rules and fields. If the validation is false outputs errors and load the same page.
Otherwise check if the customer’s email is in our database by using MCustomers’s checkCustomer function. If it returns TRUE, then set a flash message and redirect to login page.
If it returns FALSE, then add the customer to our database and set a success message and redirect to login page.
Be aware that due to $rules['city'] = ‘trim|required|alpha_dash’; a customer has to enter ‘NewYork’, ‘New-York’ or ‘New_York’ instead of ‘New York. If you don’t like this rule, you need to take out ‘alpha_dash’

login function
A cutomer will be redirected to a login page.
If email is filled, verify the customer by using MCustomers->verifyCustomer function.
This verifyCustomer function as you see below, check if the customer exist in our database. If data exists, set the PHP session, customer_id, first name, last name and other details which the customer entered in the registration page previously.
Then in the controller, it checks if the PHP session ‘customer_id’ exists. If so, set a flash message and redirect and display it. If not, set an error message and redirect.
modules/customers/models/mcustomers.php
function verifyCustomer($e,$pw){
$this->db->where('email',db_clean($e,50));
$this->db->where('password', db_clean(dohash($pw),16));
$this->db->limit(1);
$Q = $this->db->get('omc_customer');
if ($Q->num_rows() > 0){
$row = $Q->row_array();
$_SESSION['customer_id'] = $row['customer_id'];
$_SESSION['customer_first_name'] = $row['customer_first_name'];
$_SESSION['customer_last_name'] = $row['customer_last_name'];
$_SESSION['phone_number'] = $row['phone_number'];
$_SESSION['email'] = $row['email'];
$_SESSION['address'] = $row['address'];
$_SESSION['city'] = $row['city'];
$_SESSION['post_code'] = $row['post_code'];

We need to add lang(‘customer_login_enjoy_shopping’) etc to modules/webshop/language/english/webshop_lang.php
// modules/webshop/views/customerlogin.php $lang['customer_login_enjoy_shopping'] = 'Enjoy your shopping!'; $lang['customer_login_plz_login'] = 'Please login. This will fill up your details at check out automatically.'; // you can add more here.
When a customer is logged in, a message is displayed and login status and ‘Log out’ link are displayed on the top-right column.
If you see the Shop_controller.php, you will see the code which controlling this function.
system/application/libraries/Shop_controller.php
// This part is used in all the pages so load it here
// For customer login status
if(isset($_SESSION['customer_first_name'])){
$this->data['customer_status']=1;
$this->data['loginstatus']=lang('general_hello').$_SESSION['customer_first_name'].". ".lang('general_logged_in')."<br />
<a href=\"index.php/".$this->lang->line('webshop_folder')."/logout \">Log out</a>";
}else{
$this->data['customer_status']=0;
$this->data['loginstatus']="You are not logged in. <a href=\"index.php/".$this->lang->line('webshop_folder')."/login \">".lang('general_login')."</a>
<br /><a href=\"index.php/".$this->lang->line('webshop_folder')."/registration \">".lang('general_register')."</a>";
}
logout function
function logout(){
// this would remove all the variable in the session
session_unset();
//destroy the session
session_destroy();
redirect( lang('webshop_folder').'/index','refresh');
}
When a customer is logged out, the customer will be redirected to the index page.
I cant login and when I try to register. Image of recaptcha doesnt show.
Any setting to do
