magento add custom field to admin users

Question

I need to add country field to admin user creation.I have created that field.But I can't save that attribute value into database.For saving that new attribute I have used following observer event.

<admin_user_save_before>
 <observers>
 <marketplace>
 <type>singleton</type>
 <class>marketplace/observer_product</class>
 <method>adminUserCountrySave</method>
 </marketplace>
 </observers>
</admin_user_save_before>

In Oberver

public function adminUserCountrySave($observer) {
 $currentUserId = Mage::app()->getRequest()->getParam('user_id');
 $currentUserCountry = Mage::app()->getRequest()->getParam('user_country'); 
 $userData = Mage::getModel('admin/user')->load($currentUserId); 
 $userData->setUserCountry($currentUserCountry)->save();
}

But it is not working, it shows Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 65488 bytes) in D:\xampp\htdocs\SVEP3403\lib\Zend\Db\Select.php on line 421. Anyone know please help.

Answer 1

Try bellow code in observer

public function adminUserCountrySave($observer)
 {
 $user = $observer->getUser();
 $currentUserCountry = Mage::app()->getRequest()->getParam('user_country',false);
 $user->setUserCountry($currentUserCountry);
 }

• Raphael at Digital Pianism: As an explanation to OP, basically you run out of memory because your save() call is triggering the admin_user_save_before which triggers your observer and results in an infinite loop.
• Muthumahesh: Yes, I removed that save(), its working fine.Thanks for your help.
