Hook to cancel invoices for terminated products

[Believe_]

Great @DennisHermannsen

There shouldn't be that case you've mentioned at first, since only one Late Fee entry would be there on a invoice. Even if there are multiple items, there should only be one Late Fee line so there is no issues with it. 

Anyway, I'll test this out with my test cases and let you know the result as soon as possible.

Did you also include the email notifications to the administrator users upon these actions? If this even possible to implement? If so, including that would be a good function.

Thanks very much for this help, much appreciated 🙂

I've tested this and put it in production and all works fine until now. Something I missing out is a notification email to administrators, is this something you could implement on this?

You can just use this: https://developers.whmcs.com/api-reference/sendemail/

Should just be done at the end of each 'if'

FWIW, I tested this today on WHMCS 8.4.1 by ordering a product, provisioning it, leaving the invoice open, and then terminating it. It was of course the simplest of invoices with just the product line item on it, but it worked.

What if the module encounters a termination failure? Would this be better as an AfterModuleTerminate hook? Even then I'm not sure whether a failure to terminate would prevent the hook from running, but hopefully not?

add_hook('InvoiceCancelled', 1, function($vars) {
    // Get the ID of the cancelled invoice
    $invoice_id = $vars['invoiceid'];

    // Get the details of the cancelled invoice
    $invoice = localAPI('GetInvoice', array('invoiceid' => $invoice_id), 'admin');

    // Get the products associated with the cancelled invoice
    $products = $invoice['items']['item'];

    // Loop through each product
    foreach ($products as $product) {
        // If the product is terminated, cancel the invoice
        if ($product['status'] == 'Terminated') {
            localAPI('CancelInvoice', array('invoiceid' => $invoice_id), 'admin');
        }
    }
});

This hook still works perfectly per my testing, You are awesome for providing this to us and I'm super grateful.  I'm curious about Multiple products from the same invoice.  If the invoice contains 5 different products, but only 1 is terminated, it seems to terminate the entire invoice. Is there a way to require the hook to check that ALL the products have been terminated before cancelling?

Like most feature requests, they're ignored. Pointless to vote.
