Ubercart

I'm somewhat surprised this isn't in core. In recent implementations I've worked around it by coding some exceptions that don't display the "add to cart" button for particular products, and replaces it with a Coming Soon "button" which is not clickable (and styled as being grayed-out).

Yea! cause I was planning on using stock notify for my site which is a good module but there was one problem there was no way of seeing what items people wanted to be notified about so we can reorder them. Unless you went into your data base. they should of had a place in the shopping cart that showed a list of the items people wanted to be notified in a chart format with the number of people that wanted to be notified per product, the most request item, what has been reordered and how many time ect... basic product stats. But enough about that. Back to the Back order the only thing with uc_attribute_stock_filter is that it's for 6.0 only I'm still using 5. what i did was modify the uc_inventory_api module example:

else
{
// No attributes...

// If its a simple product with no attributes see if there are
// enough in stock to sell one more

$product = $form['#parameters'][1];

if(!uc_inventory_api_can_add($product->model, $form['qty']['#value']))
{
$form['submit']['#disabled'] = FALSE;
$form['submit']['#value'] = t('Back Order');
}
}
break;
}
}

This part I changes the out of stock button to Back Order and made it clickable. Next I wanna edit this:

/**
* Implement hook_add_to_cart
*
* Stop the adding of the item to cart if the Inventory Manager says 'Nay!' (false).
*/
function uc_inventory_api_add_to_cart($nid, $amount, $data)
{
// Get the products ID (SKU).

if(empty($data['model']))
{
$product = node_load($nid);
$sku = $product->model;
}
else
{
$sku = $data['model'];
}

// Ask the current Inventory Manager if its ok to add this amount to the cart.

if(!uc_inventory_api_can_add($sku, $amount))
{
return array(
array(
'success' => FALSE,
'message' => t('Sorry, there is not enought in stock to add this to your cart.')
)
);
}
}

I wanna change it so that it will still allow you to add the items to cart but still show the message, but I want to change the message to "Sorry, there is not enough in stock your item will be add to your cart but placed in back order" There are 2 more parts that have to be change that effect sites with quantity adding in the catalog and quantity adding in the shopping cart adn I was trying to do the same thing allow the adding to negative stock and keep the message, but change to the message from:

'message' => t('Sorry, there is now %quantity \'%product_name\' left in stock.', array('%quantity' => $qty_in_stock, '%product_name' => $product->title))

to:

'message' => t('Sorry, there is now %quantity \'%product_name\' left in stock.', array('%quantity' => $qty_in_stock, '%product_name' => $product->title' your items will be placed in back order))

I have allot of ideas of changes to make to different module but it seems that people don't have the time to listen. Like i said before I willing to pay for the help to make these changes for every bodies sake.
