How can I get a confirm message after adding to cart?

Hi everybody!
I set the "Display Cart After Adding Product" to false in Admin->My Store section,
but I would like the client could see a** message ** (with javascript for example) that confirms the product was successfull added to his shopping cart.
Do someone have an idea how could I do that, for example using the same layer that appears to advise a form check failure while adding a product?
If you could tell me at least which files to check I would appreciate very much :yes:
Thank you

You would need to add a message to the: init_cart_handler.php

I would place it at the bottom of this IF statement:

  if (DISPLAY_CART == 'true') {
    $goto =  FILENAME_SHOPPING_CART;
    $parameters = array('action', 'cPath', 'products_id', 'pid', 'main_page');
  } else {
    $goto = $_GET['main_page'];
    if ($_GET['action'] == 'buy_now') {
      $parameters = array('action', 'products_id');
    } else {
      $parameters = array('action', 'pid', 'main_page');
    }
    $messageStack->add_session('header', SUCCESS_PRODUCTS_ADDED_TO_CART, 'success');
  }

Then define the message: SUCCESS_PRODUCTS_ADDED_TO_CART

Note: if time, I will play a bit with this for v1.3.6 as it would be helpful to have a meaning full message ... but I need to test based on errors and such what more may be needed under a baziilion conditions ...

Note: test 1 item is not added due to error on required info ... you get the error message and the success message ...

Best to manage this with a paramater deeper in the code ...

Sorry to dash your hopes to heck ...

But, I will look into this further ...

Thank you for your attempt and test...you helped me to understand how a message is dispatched and where to start looking at.
I changed the classes/shopping_cart.php file, adding the line of code with the message dispatch at the end of the "actionAddProduct" fuction, in case of no errors:

if ($the_list == '') {
	  $messageStack->add_session('product_info', SUCCESS_PRODUCTS_ADDED_TO_CART, 'success');
...

And it works :D

Actually, to avoid the message showing when there are errors for various issues this had to be added to the shopping_cart class ...

This has been added to the upcoming v1.3.6 to display a message when a product or products are added to the cart and the Display Shopping Cart is turned off ...

NOTE: The message displayed can also be disabled just by setting the defines for the two messages to '' in the language file ...
