predispatch on a adminthml controller

Question

I am using magento 1.7. I would like to have a event before the call of this method Mage_Adminhtml_Sales_Order_CreateController save.

I tried to do it like this :

Config.xml :

 <adminhtml>
        <events>
            <controller_action_predispatch_sales_order_create_save>
                <observers>
                    <gfi_tnt_add_relay_quotes>
                        <type>singleton</type>
                        <class>Gfi_TNT_Model_Observercontroller</class>
                        <method>addTntRelayQuote</method>
                    </gfi_tnt_add_relay_quotes>
                </observers>
            </controller_action_predispatch_sales_order_create_save>
        </events>
</adminhtml>

app/code/community/Gfi/TNT/Model/Observercontroller.php :

class Gfi_TNT_Model_Observercontroller extends Mage_Adminhtml_Controller_Action
{
    public function addTntRelayQuote() {
     ........
    }
}

What is wrong in my code? Could you help me?

I found my mistake. With the help of this post : https://stackoverflow.com/questions/31468618/need-a-magento-event-that-will-fire-after-changing-the-shipping-address-of-an-or

I found what was wrong. The name on a controller event in the adminhtml is all the time like this :

<adminhtml>
        <events>
               <controller_action_predispatch_adminhtml_...>
               </controller_action_predispatch_adminhtml_...>
        </events>
</adminhtml>

I thought it was useless to add adminhtml before the path of my controller but not.

So in my case , my config.xml is :

 <adminhtml>
        <events>
                <controller_action_predispatch_adminhtml_sales_order_edit_save>
                    <observers>
                        <gfi_tnt_add_relay_quotesss>
                            <type>singleton</type>
                            <class>Gfi_TNT_Model_Observercontroller</class>
                            <method>addTntRelayQuote</method>
                        </gfi_tnt_add_relay_quotesss>
                    </observers>
                </controller_action_predispatch_adminhtml_sales_order_edit_save>
       </events>
</adminthtml>

I hope it can help :)

I assume you are trying to save some custom data after the order is saved from the backend

You can try this event

 <adminhtml>
    <events>
        <sales_order_save_after>
            <observers>
                <gfi_tnt_add_relay_quotes>
                    <type>singleton</type>
                    <class>Gfi_TNT_Model_Observercontroller</class>
                    <method>addTntRelayQuote</method>
                </gfi_tnt_add_relay_quotes>
            </observers>
        </sales_order_save_after>
    </events>
</adminhtml>

Observer

<?php
class Gfi_TNT_Model_Observercontroller
{
    public function addTntRelayQuote() {
        $order = $observer->getEvent()->getOrder();
        // you can use this object and save your additional data
    }
}

You can also try sales_order_save_before event.
