Module/hook which can generate 2 invoice series? (For India)

[DemoTiger]

Hello,

 

 

I want something like:

Other Country Invoice format:  #CompanyName-Number.

India Invoice format: #India-Number(Must be separate from Other country's invoice number)

 

Example Invoice No:

#Dewlance-1

#Dewlance-2

 

Indian Invoice Example:

#India-1

#India-2

 

 

Any Idea? This is required in India ;/

 

 

Thanks.

Where does this have to show?  Just in the PDF for example or like in even on your admin side?  If just the PDF / invoice page, you could change the template files and add {$clientsdetails.country} to where the invoice number is shown.

It's doable with custom scripts but before you start coding keep in mind that it's a nightmare for tens of reasons. It took me months to achieve similar results. You need to use all the following action hooks:

• InvoiceCreation
• InvoiceCreated
• InvoiceCreationPreEmail
• InvoiceCreationAdminArea
• InvoicePaid
• InvoicePaidPreEmail

Depending on other factors you may have to use also AdminAreaHeaderOutput. In fact Add Transaction from backend uses an ajax POST therefore you'll probably need to code a fallback to get your things done. Here comes the bad part. All the above hook points are redundant in inexplicable ways so your scripts must be smart enough to trigger only once otherwise you mess up your invoice numbering. Good luck. You'll need it.

Don't forget that you also need to abort all invoice-related email notifications so that you can fix invoice number before customers receive PDF and emails with the default numbering of WHMCS. Obviously such emails must be re-sent via API.
