I am working on a project that needs to tweak admin order creation function of magento.

I need to remove an item and then add another item programmatically while creating order.

For example, few items are already added to order, now if product id matches with my_product_id, remove that product from quote and add new product (my_new_product) to order.

It will not be from observer, since I will need to add a button to call this action and do the job.

I have successfully added a button and linked to my custom controller.

I have gone through loads of links, but no luck.

Please suggest.

Update

Since you only need to tweak the existing admin order creation you could hook to: sales_order_save_before or adminhtml_sales_order_create_process_data but make sure you add this in to the <adminhtml> node in your config.xml.

Once in your Observer.php you can remove the items you wish, I would instead try to hook to a quote event also in the <adminhtml> node and then remove the item at a quote level if possible.

To add an item to the quote:

$quote->addProduct($product, new Varien_Object($eventArgs));
$quote->save();

To remove an item from the quote:

$quote->removeItem($item->getItemId())->save();

Then you can have magento create the admin order:

$adminSalesOrderCreate = Mage::getSingleton('adminhtml/sales_order_create');
$adminSalesOrderCreate->setQuote($quote)->save();

  • I have to get quote from admin create order section. Or is it onepage checkout in admin too? Commented Jun 5, 2015 at 10:34
  • yes, do it from admin. And also make sure you use Mage::getSingleton('adminhtml/sales_order_create'); Check my updated answer

After digging up for few days, I have been able to get the result.

A big thanks to @lloiacono for pointing me to right direction, however his/her answer wasn't good enough.

In my controller file:

public function removeAndAddAction()
{
    $quote = $this->_getSession()->getQuote();
    foreach($quote->getAllItems() as $item){
        $quote->removeItem($item->getId());
        $product = Mage::getModel('catalog/product')->load($item->getProductId());
        $quote->addProduct($product, 1);
    }
    $quote->collectTotals()->save();

    $this->_redirect('*/sales_order_create');
}

//get session
protected function _getSession()
    {
        $session = Mage::getSingleton('adminhtml/session_quote');

        return $session;
    }
