Filling specific uniquely named fields directly

[sergeybloom]

Relative pypdf newbie here. Not sure if this can be done already or not. I was hoping to fill a field using a unique field name. Something like:

writer.update_form_field_value({"form1[0].#subform[0].Pt1Line2a_FamilyName[0]": "some filled in text"})

Is something like that possible? Or, if not, could it be an idea for version 4?

Unless I am mistaken, the only way to place values in form fields is by specifying page numbers:

from pypdf import PdfWriter

writer = PdfWriter(clone_from="g-28.pdf")

writer.update_page_form_field_values(
    writer.pages[0], {"form1[0].#subform[0].Pt1Line2a_FamilyName[0]": "some text"}
)

with open("g-28.pdf", "wb") as output_stream:
    writer.write(output_stream)

I hope my question makes sense. Thank you!
