Adding an attribute to customer order page on the backend

Question

I want to add a custom attribute which i have already created to the order page in the back end. I have used this in my config.xml file to add the attribute to the customer account page, but I want to access the same field from the Order page.

<?xml version="1.0"?>
<config>
    <modules>
        <Shailendra_CustomField>
            <version>0.1.0</version>
        </Shailendra_CustomField>
    </modules>
    <frontend>
        <routers>
            <customfield>

                <setup>

                    <class>Mage_Customer_Model_Entity_Setup</class>
                </setup>
                <connection>
                    <use>core_setup</use>
                </connection>
            </customfield_setup>
            <customfield_write>
                <connection>
                    <use>core_write</use>
                </connection>
            </customfield_write>
            <customfield_read>
                <connection>
                    <use>core_read</use>
                </connection>
            </customfield_read>
        </resources>
    </global>
</config>

Would i have to just add something to this config file. If so what would i have to add.

Assuming that you want to add my_custom_input_field to your order and add a field to your admin create order page (to add the field to the frontend you just need to add the input field to the front template and double check the observer)

In /app/code/local/MageIgniter/CustomOrderStatus/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <MageIgniter_CustomOrderStatus>
            <version>1.1</version>
        </MageIgniter_CustomOrderStatus>
    </modules>

    <global> 
         <fieldsets>
            <sales_convert_quote>                           
                <my_custom_input_field><to_order>*</to_order></my_custom_input_field>
            </sales_convert_quote>

            <sales_convert_order>                                              
                <my_custom_input_field><to_quote>*</to_quote></my_custom_input_field>
            </sales_convert_order>
        </fieldsets>
        <helpers>
            <customorderstatus>
                <class>MageIgniter_CustomOrderStatus_Helper</class>
            </customorderstatus>            
        </helpers>

        <models>
            <customorderstatus>
                <class>MageIgniter_CustomOrderStatus_Model</class>
                <resourceModel>customorderstatus_mysql4</resourceModel>
            </customorderstatus>
        </models>
        <resources>
            <customorderstatus_setup>
                <setup>
                    <module>MageIgniter_CustomOrderStatus</module>
                    <class>Mage_Sales_Model_Mysql4_Setup</class>
                </setup>
                <connection>
                    <use>core_setup</use>
                </connection>
            </customorderstatus_setup>
            <customorderstatus_write>
                <connection>
                    <use>core_write</use>
                </connection>
            </customorderstatus_write>
            <customorderstatus_read>
                <connection>
                    <use>core_read</use>
                </connection>
            </customorderstatus_read>
        </resources>

        <events>
            <adminhtml_sales_order_create_process_data_before>
                <observers>
                    <customorderstatus>
                        <type>singleton</type>
                        <class>customorderstatus/observer</class>
                        <method>saveCustomData</method>
                    </customorderstatus>
                </observers>
            </adminhtml_sales_order_create_process_data_before>
        </events>

        <blocks>
            <customorderstatus>
                <class>MageIgniter_CustomOrderStatus_Block</class>
            </customorderstatus>
        </blocks>
    </global>
</config>

In /app/code/local/MageIgniter/CustomOrderStatus/sql/customorderstatus_setup/mysql4-install-1.1.php

<?php
$installer = $this;
$installer->startSetup();

$installer->addAttribute("order", "my_custom_input_field", array("type"=>"varchar"));
$installer->addAttribute("quote", "my_custom_input_field", array("type"=>"varchar"));
$installer->endSetup();

In /app/code/local/MageIgniter/CustomOrderStatus/Model/Observer.php

class MageIgniter_CustomOrderStatus_Model_Observer 
{
    public function saveCustomData($event)
    {
        $quote = $event->getSession()->getQuote();
        $quote->setData('my_custom_input_field', $event->getRequestModel()->getPost('my_custom_input_field'));

        return $this;
    }
}

(You should avoid make changes to core default - you should do some research on way around this)

In /app/design/adminhtml/default/default/template/sales/order/view/info.phtml

<?php if($_order->getMyCustomInputField()): ?>
<tr>
    <td class="label"><label><?php echo Mage::helper('sales')->__('My Custom Input Field') ?></label></td>
    <td class="value"><strong><?php echo $_order->getMyCustomInputField() ?></strong></td>
</tr>
<?php endif; ?>

In /app/design/adminhtml/default/default/template/sales/order/create/form/account.phtml

(to add to frontend change the value="<?php echo Mage...>")

<input id="my_custom_input_field" name="my_custom_input_field" value="<?php echo Mage::getSingleton('adminhtml/session_quote')->getQuote()->getMyCustomInputField() ?>" class="input-text" type="text">
