I'm using this code to login a customer programmatically:

require_once ("app/Mage.php");    


// Init a Magento session. This is super ultra important
Mage::getSingleton('core/session', array('name' => 'frontend'));

// $customer Mage_Customer_Model_Customer
// We get an instance of the customer model for the actual website
$customer = Mage::getModel('customer/customer')

// Load the client with the appropriate email
$email = "user@email.com";

// Get a customer session
$session = Mage::getSingleton('customer/session');

// Login an check the customer by his database userId
if ($session->loginById($customer->getId())) {
    echo '<div>Succesfull loginById</div>';
} else {
    echo '<div>Error in loginById</div>';

if ($session->isLoggedIn()) {
    echo '<div>Welcome</div>';
} else {
    echo '<div>Denied</div>';

But it's not working, the result I'm getting in the browser is:

Succesfull loginById


What could be the issue here?


Some new information: I've tried this script on a different shop we have running and it works perfectly there. Why would it work on one but not the other?


More troubleshooting has resulted in the conclusion that $session->getId() returns NULL while it should return an actual ID. Still no idea why this shop doesn't return a session id while the other one does.

  • Where you using this code?

    In a PHP script outside of Magento, I've included app/Mage.php in the script.

Where $customer is a loaded instance of Mage_Customer_Model_Customer

  • Adding this doesn't really seem to change anything.

  • setCustomerAsLoggedIn() is already available in loginById() function Oct 7 '15 at 9:49
  • Code works for me. loginById() loads the customer model again so you should go with setCustomerAsLoggedIn() anyway. Ensure your email has an active account. Oct 7 '15 at 10:07
require_once ("app/Mage.php");

$websiteId = 1;
Mage::run('store_view_code', 'store');
Mage::init($websiteId, 'website');

$email = 'foo@bar.com';

$customer = Mage::getModel('customer/customer');
$session = Mage::getSingleton('customer/session');

if ($customer->getId()) {

    $url = 'http://www.domain.com/test';
    header('Location: ' . $session->getAfterAuthUrl());
