Concatenate PDF Forms with Unique Suffix

Merging PDF forms can lead to conflicts if multiple files contain fields with the same name. Using Aspose.PDF for Python, developers can assign a unique suffix to form fields during concatenation. The unique_suffix property in the PdfFileEditor class automatically renames conflicting fields, preserving interactivity and ensuring that all form data remains functional. This approach is ideal for combining surveys, applications, or any interactive PDF documents programmatically.

1. Create a PdfFileEditor Object and Set Unique Suffix.
2. Merge PDF Forms.

import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

import sys
from os import path

sys.path.append(path.join(path.dirname(__file__), ".."))
from config import set_license, initialize_data_dir


def concatenate_pdf_forms(files_to_merge, output_file):
    # Create a PdfFileEditor object
    pdf_editor = pdf_facades.PdfFileEditor()
    pdf_editor.unique_suffix = (
        "_xy_%NUM%"  # Set a unique suffix to avoid form field name conflicts
    )
    pdf_editor.concatenate(files_to_merge, output_file)
