Magento – Fatal error: Call to a member function on non-object

magento-1magento-1.6magento-1.7

I am developing a custom module where an xml file will be created after order completion for each order.

I have called a function exportOrder on occuring of an event "sales_order_place_after". Following is the code of my function

public function exportOrder($observer) {
    $order = $observer->getEvent()->getOrder();
    Mage::getModel('meteorify_observerexample/export')->exportOrder($order);
    return true;
}

Now In Export.php file i have written the logic of creation of an xml file.Export.php file is placed in the folder Meteorify/Observerexample/Model/ folder.

Here i have called the function exportOrder from the file Export.php using Mage::getModel('meteorify_observerexample/export')->exportOrder($order); but i am getting the error

"Fatal error: Call to a member function exportOrder() on a non-object
in
/home/user_www/aliasgar/magentotesting/app/code/local/Meteorify/Observerexample/Model/Observer.php
on line 6"

Can anyone help me on this ?

The problem is in the config.xml file in the declaration of the model alias.
In your case is:

<models>
    <meteorify_observerexample>
        <class>Observerexample_Model</class>
    </meteorify_observerexample>
</models>

But it should be

<models>
    <meteorify_observerexample>
        <class>Meteorify_Observerexample_Model</class>
    </meteorify_observerexample>
</models>

Magento 1.x Fatal Error – Call to a Member Function getData() on a Non-Object

You are using the event incorrectly.

In event checkout_onepage_controller_success_action

the order is not sent as an object, but as the order id. (as order_ids)

Mage::dispatchEvent('checkout_onepage_controller_success_action', array('order_ids' => array($lastOrderId)));

(ref Mage_Checkout_OnepageController::successAction)

Thus in your observer you need to get the id, as such:

$orderIds = $observer->getEvent()->getOrderIds(); // returns an array 
$orderId = array_shift($orderIds);

and instantiate the order object using

$order = mage::getModel('sales/order')->load($orderId);

(the above written off the top of my head, but the jest of it should be correct)

Magento 1.6 Collection – Fatal Error: Call to a Member Function getCollection() on a Non-object

The error basically tells us that Mage::getModel('easylife/easylife') doesn't return a valid class. Please make sure the file Ics/Easylife/Model/Easylife.php exists and looks somewhat like the code posted below, this should give you access to the resource model.

class Ics_Easylife_Model_Easylife extends Mage_Core_Model_Abstract
{
   public function _construct()
   {
      parent::_construct();
      $this->_init('easylife/easylife');
   }
}

If that doesn't work I'd advice you to check out this wikipage which clearly outlines what you need to do on using collections.
