以编程方式更新magento客户

Question

I'm trying to modify existing customers data on magento programmatically, but i have errors, hope someone can help me with this.

require_once('../app/Mage.php');
ini_set("error_reporting",E_ALL);
ini_set("display_errors",true);
umask (0);
Mage::app('admin');

$email = $_REQUEST['email'];
$firstname = $_REQUEST['firstname'];
$lastname = $_REQUEST['lastname'];
$newEmail = $_REQUEST['newEmail'];
$method = $_REQUEST['method'];
$user_id = $_REQUEST['user_id'];


$customer = Mage::getModel('customer/customer');
        $customer->setWebsiteId(Mage::app()->getWebsite()->getId());
        $customer->loadByEmail($email);
        $customer->setFirstname = $firstname; 
        $customer->setLastname = $lastname; 
        $customer->setEmail = $newEmail; 
        $customer->save();  

Here is the error message

Fatal error: Uncaught exception 'Mage_Customer_Exception' with message 'Customer email is required' in /home/insateck/www/zzWEBS/MAGENTO/ZZpruebasEXPRIMENET/app/Mage.php:580 Stack trace: #0 /home/insateck/www/zzWEBS/MAGENTO/ZZpruebasEXPRIMENET/app/code/core/Mage/Customer/Model/Resource/Customer.php(76): Mage::exception('Mage_Customer', 'Customer email ...')

Answer 1

You can modify the condition for saving the new email as:

$customer = Mage::getModel('customer/customer');
$customer->setWebsiteId(Mage::app()->getWebsite()->getId());
$customer->loadByEmail($email);
if($customer->getId()>1){
     $customer2 = Mage::getModel('customer/customer');
     $customer2->setWebsiteId(Mage::app()->getWebsite()->getId());
     $customer2->loadByEmail($newEmail);
     if($customer2->getId()<1){
        $customer->setEmail($newEmail); 
     }
     $customer->setFirstname($firstname); 
     $customer->setLastname ($lastname); 
     $customer->save();
 }

The updated condition will avoid the fatal error.
