add new data in invoice

[juampa]

Hello,

We need to be able to edit the invoice that the client sees in a personalized way.

 

We need to add data that is recorded in a personal table.

 

The data are inserted by making a hook when the invoice is generated. In this way we already have the data related to the id of the invoice in a new table.

 

Now what we need is to be able to display these data within the invoice. I'm noticing that the Smarty that uses the whmcs does not accept the {php} {/ php}

 

Then we need to know what is the correct way to take data from the database and write it on the invoice so that it can be seen in it.

 

Thank you so much!
