How to include token or variable for Invoice number under the message templates for Memberships - Receipt (on-line)

Question

I need to send Invoice number in the message templates for Membership Receipt Online, but I don't see any token or variables associated for Invoice Number which I can use to place it

is there any way we can place the invoice number in the message templates ?

Answer 1

The tokens you can use in a message template are a bit random, just what the developer added to the template. In this case, the contribution id can be found with {$contributionID}. However, that is not the same as the invoice_number. I could not find a token for the invoice number. But the templates are generated by smarty, and in smarty you can use the CiviCRM api. So the following line gets the invoice number:

{crmAPI var='invoiceReference' 
        entity='Contribution' 
        action='getvalue' 
        return="invoice_id" 
        id=$contributionID}

You can print it with {$invoiceReference}

Answer 2

The solution proposed seems very good: {crmAPI var='invoiceReference' entity='Contribution' action='getvalue' return="invoice_id" id=$contributionID} You can print it with {$invoiceReference}

But I obtain an array, in which way I could extract the invoice_number?
