add credit to specific products

[Sanora Dev]

Hello everyone,

I'm searching for a way to assign specific products that can use credits and products that can't. for example, if a customer has credit he or she can use it for all hosting plans, but not for google cloud plans.

Is there a hook that i can use for this or maybe a third party addon? I've search and googled for days now, but couldn't find anything about it. The only thing i found is an old topic that wanted (in general) the same as what i'm looking for.

Old topic:

Thanks,

Elias

There're two cases where you need to check this:

• during renewal invoice creation
  When a renewal invoice is issued, if there's available credit WHMCS will automatically apply to it
   
• in client area, when the user can select an unpaid invoice and decide to apply credit to it
   

The second one, I guess, it's quite easy: just modify the involved .tpl with some kind of IF clause

The first one is a little more complicated: here the code of a hook that prevent automatic credit application to new invoices if the credit is not sufficient to full pay the invoice:

//
// remove applied credit to invoices, when credit applied is not sufficient to fully pay 
//
function remove_credit_from_new_invoice($vars) {
    if ($vars['status']=="Paid") { return; }
    $postData=array('invoiceid' => $vars['invoiceid'], );
    $invoicedata = localAPI('GetInvoice', $postData);
    if ( $invoicedata['credit'] != 0 AND $invoicedata['balance'] != 0 ) {
    	$postData = array(
    		'invoiceid' => $vars['invoiceid'],
    		'amount' => - $invoicedata['credit'],
		);
        $res = localAPI('ApplyCredit', $postData);
        logactivity('Insufficient credit removed by hook: invoice id# '.$vars['invoiceid'].' - credit removed '.$invoicedata['credit'],$vars['user']);
    }  
}

add_hook('InvoiceCreationPreEmail', 5, "remove_credit_from_new_invoice" );

 

You need to modify it in order to:

• check the kind of service billed
• set the status of the invoice back to "unpaid" if it was fully paid with credit

Hope this will be helpful to you.
