Customer

Things about Account, Address, Attributes, Forms, Groups, Observer, Session and Widgets especially for customer.

Session

Information about the current customer or visitor of this page.

Check if customer is logged in

    <?php

    $logged_in = Mage::getSingleton('customer/session')->isLoggedIn(); // (boolean)

    ?>

Get current customer

<?php

    public function getCustomer()
    {
        return Mage::getSingleton('customer/session')->getCustomer();
    }

?>

Get random customer

<?

/* @var $collection Mage_Customer_Model_Resource_Customer_Collection */
$collection = Mage::getModel('customer/customer')->getCollection();
$collection->getSelect()->order('RAND()');
$collection->load();

foreach ($collection as $customer)
{
    /** @var Mage_Customer_Model_Customer $customer */

    ###
}

?>

Login as customer / user in Magento

If you want to take over the control of an other customer load him and tell the session to login:

<?php

/** @var $customer Mage_Customer_Model_Customer */
$customer = Mage::getModel('customer/customer');

// get the customer (by Mail)
$customer->loadByEmail('[email protected]');

/** @var $session Mage_Customer_Model_Session */
$session = Mage::getModel('customer/session');
$session->loginById($customer->getId());

?>

Now you are acting as a different customer. If needed remember to switch back to your account by doing the same thing again with your mail address.

Customer

Get customer by attribute

Sometimes you need to filter your customers by attribute. An attribute can be a foreign customer number or other identities. Take this method or it's body to search for such customer:

<?php

    /**
     * Load customer by attribute
     *
     * @see Mage_Catalog_Model_Abstract::loadByAttribute()
     * 
     * @param Mage_Eav_Model_Entity_Attribute_Interface|integer|string|array $attribute Attribute to filter
     * @param null|string|array                                              $value     Value to meet
     *
     * @return array
     */
    public function loadByAttribute($attribute, $value)
    {
        // Get collection and filter by attribute value pair
        $collection = Mage::getModel('customer/customer')->getCollection()
            ->addAttributeToFilter($attribute, $value);

        $customerSet = array();
        foreach ($collection as $customer)
        {
            /** @var Mage_Customer_Model_Abstract $customer Customer that fits the pattern. */
            if (is_object($customer))
            {
            	// return $customer; // will instantly get the first found customer
            
                // append to array
                $customerSet[] = $customer;
            }
        }
        
        return $customerSet;
    }

You received an array with all customer that fit the attribute and value.

Update all subscribers into a customer group (e.g. 5)

UPDATE
	customer_entity,
	newsletter_subscriber
SET
	customer_entity.`group_id` = 5
WHERE
	customer_entity.`entity_id` = newsletter_subscriber.`customer_id`
AND
	newsletter_subscriber.`subscriber_status` = 1;
