[Solved] How to create a "flatten" button for PDF form

[leftdefense]

Hi,

I am currently using OpenOffice Writer to create simple PDF forms for my employees.
Howerver, legally, these forms need to be archived for a really long time.

So i need to be able to quickly convert the dynamic PDF form to a static (or flatten) PDF/A. Preferably with a single click button.
A normal flatten PDF (not PDF/A) would be okay too, since my e-sign program can convert a PDF to PDF/A.

I actually acheive this manually by using a PDF printer. It is a pain since i have to choose the printer, specify the format and create a separate file.

I was thinking about setting a button on the form that activates some code that flattens the current document. However, even though adding a button is easy, i have never coded in OpenOffice.

Can someone help me create and set the code for this button?

Thanks a lot.

Just set the PDF/ A-1a setting in the /File /Export as PDF.

It does flatten the .ODT form but it is not what i'm looking for.
I want to fill a PDF form (so the field must not be flatten at first) and then with a button, they go flatten.
The button that flattens the PDF form will be executed after filling the form in Adobe Reader, not in OO. (The users that will fill the form won't even have OO installed)

Unable to execute this kind of action.
Exported PDF with AOO can not embed any Javascript: https://bz.apache.org/ooo/show_bug.cgi?id=62843

Just open a new instance of the same PDF

It's what i thought... to do what i want, we would need to run Javascript right?
This is so sad for me

Thanks for the answer Bidouille.
