How do I add a tab to the Sale Order Admin Page?

Question

I want to add a custom tab to the order page in the admin of magento. Is there a way to do this with a simple override?

Assuming you know how to do a module, here are the steps you need to perform:

1. layout update: in your admin's xml layout file you want to "listening" to the admin's order view rendering handle and add your tab:

   
       
           
               the_name_of_your_tabthe_block_alias_of_your_module/path_to_your_tab_file
           
       
   
   

2. the tab file: I generally try to respect Magento's folder structure, so this file would be in app/code/local-or-community/YourNamespace/YourModule/Block/Adminhtml/Order/View/Tab/File.php and will have at least:

   setTemplate('yourmodule/order/view/tab/file.phtml');
       }
   
       public function getTabLabel() {
           return $this->__('Tab label');
       }
   
       public function getTabTitle() {
           return $this->__('Tab title');
       }
   
       public function canShowTab() {
           return true;
       }
   
       public function isHidden() {
           return false;
       }
   
       public function getOrder(){
           return Mage::registry('current_order');
       }
   

3. The .phtml file, which has to respect the path you specified in the block's __construct(), and should hace something like:

   
       
   
           
   __('a title'); ?>
       
       
   
           the content you want to show
       
   
   

Hope That Helps
