You will find these answers in the guides - you should always search the guides before asking in the forum
If you look at the themes, you can get some idea of the variable names, but in general they are not exposed
Why don’t you include details in your topic to make it easy for everyone to know the topic without opening the topic and also to help people find your topic in the future if they get similar issues and search the forum?
You can’t change the name in the form used to edit the transaction, if that is what you are asking. You can change the name on the form in the View and print versions using the custom title option
If you are coding something, you should already know how important it is to be precise when discussing such things. There is no such thing in Manager as a “template.” There are email templates and themes. The former are written in HTML. The latter are written in Liquid. Use of both is described in the Guides.
When looking for specific variables applicable to one transaction type, use the Batch Create function to get a list of variables. You will see that sales invoices include the variable DueDate. There is also a Guide for that.
When creating themes, understand that all transactions share the same theme variables. Those variables are reassigned based on transaction type. The due date on a sales invoice is an element of the array variable {{ field.text }}. Its label is an element of another array named {{ field.label }}.
Here again, your question is confusing because of your terminology. What do you mean by “languages-output?” Email templates and themes are written in the applicable coding languages. There is no “output,” whatever you meant by that. Language preference for the program itself is selected as described in this Guide: https://www.manager.io/guides/9156.
Okay, thank you i will have a look at all this when i am back from vacation.
Can you say me please the array number of due date please?
{{ field[?].text }}
PS. I just wonder why the variables are not disclosed, there’s nothing wrong with it, I completely understand that it’s not opensource, but the variables are part of a well configured system and belong in the guides (constructive criticism)
