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 ?

  • How does the config.xml file of your module look like? I have a hung the helpers alias is not set properly. – Marius♦ Aug 12 '13 at 11:08
  • This is how my helper config looks "<helpers> <orderexport> <class>Meteorify_Observerexample_Helper</class> </orderexport> </helpers>" – Dexter Aug 12 '13 at 11:14
  • Models and events looks like this "<models> <meteorify_observerexample> <class>Observerexample_Model</class> </meteorify_observerexample> </models> <events> <checkout_onepage_controller_success_action> <observers> <sales_order_place_after> <type>singleton</type> <class>Meteorify_Observerexample_Model_Observer</class> <method>exportOrder</method> </sales_order_place_after> </observers> </checkout_onepage_controller_success_action> </events>" – Dexter Aug 12 '13 at 11:16
  • Please add the contents of config.xml to the question. It's easier to read and follow. – Marius♦ Aug 12 '13 at 11:33

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>

  • Thanks for your reply it was a stupid mistake by me. As i am a newbie in magento, I repeatedly tend to make such mistakes. Now please can you guide me through this mistake too. In the file Export.php I have wrote the code for creating the order xml. Now i read from one of the article regarding fetching the orderdata using observer object. I am writing the code in the next comment – Dexter Aug 12 '13 at 11:55
  • Following is the code i have wrote "public function exportOrder($order){ $dirPath = Mage::getBaseDir('var').DS.'export'; //if the export directory does not exist, create it if (!is_dir($dirPath)) { mkdir($dirPath, 0777, true); } $data = $order->getData();" Here i am getting the error 'Fatal error: Call to a member function getData() on a non-object in /home/user_www/aliasgar/magentotesting/app/code/local/Meteorify/Observerexample/Model/Export.php on line 12' which is the line of code '$data = $order->getData()' – Dexter Aug 12 '13 at 11:57
  • @Dexter. That is a different issue. Please post an other question with your code and your problem. Don't mix them. – Marius♦ Aug 12 '13 at 11:57
