I copied the template using Adobe Reader. With this template, I achieve the desired result with the above code, namely pages 1–3. PDFs truly are a riddle wrapped in a mystery inside an enigma (W. Churchill).]]> Mon, 03 Feb 2025 14:38:30 +0000 http://www.quickpdf.org/forum/merging-pdf-pages-empty-formfields_topic4044_post16388.html#16388 <![CDATA[Merging PDF Pages: Empty FormFields : Hello everyone,The fields are...]]> http://www.quickpdf.org/forum/merging-pdf-pages-empty-formfields_topic4044_post16387.html#16387 Author: Skandinavier

Hello everyone,

The fields are AcroForm.

I choose to define all possible fields and remove the unnecessary ones before saving.
However, I'm encountering a strange issue:
When generating the document, I end up with the first page repeated three times—although the same code works perfectly fine with a different template.

Could someone take a look at the code below and help me understand why this is happening?

 Dim fileName As String = "D:\....\...\Template.pdf"

        Dim Final_Doc As Integer
        Dim Used_Doc As Integer

        Call QP.LoadFromFile(fileName, "")

        '1. Page
        Call QP.SetFormFieldValueByTitle("Titel", "First Page")
      
        Final_Doc = QP.SelectedDocument()

        '2. Page

        Call QP.LoadFromFile(fileName, "")

        Call QP.SetFormFieldValueByTitle("Titel", "Second Page")
       
        Used_Doc = QP.SelectedDocument()

        QP.SelectDocument(Final_Doc)
        QP.MergeDocument(Used_Doc)


        '3. Page

        Call QP.LoadFromFile(fileName, "")

        Call QP.SetFormFieldValueByTitle("Titel", "Third Page")
        
        Used_Doc = QP.SelectedDocument()

        QP.SelectDocument(Final_Doc)
        QP.MergeDocument(Used_Doc)


        Call QP.SaveToFile("D:\....\...\Result.pdf")

        ' Remove document from memory
        QP.RemoveDocument(Final_Doc)


Thanks in advance!

With
//...
if (QP.GetXFAFormFieldCount > 0) or (QP.FormFieldCount > 0) then...
//...
you can check if there are acro form fields or xfa form fields.

Hi @Skandinavier,
Try flattening the form fields (turning them into static content) before merging. This should keep the filled values. You can check if the fields are AcroForm or XFA using Adobe Acrobat. If flattening doesn’t work, copy the fields to a new page first.

Hi Ingo,

Thank you for your answer.

It doesn't work even with a single field (I tested it to rule out potential issues with duplicate names).
The form was originally created with LibreOffice. How can I find out the type of the form fields?
I am using the DebenuPDFLibraryDLL1811.
If merging the pages doesn't work this way, I’m considering how to place all fields on one page and delete the unnecessary ones before saving/printing.

Greetings

Hi :)

It's necessary that each form field has a unique name. If you put several pages with form fields on a new single page you should have an eye on this fact if you don't want to run into problems.
Another point: What type of form fields you're using? Acro or xfa? QuickPDF doesn't offer much support using xfa.

Hi everyone,

I’m working on merging two or more PDF pages into a single page using the "DrawCapturedPage" function. This works fine overall, but I’ve run into a problem:

The form fields that I previously filled using "SetFormFieldValueByTitle" remain empty in the merged PDF page.

Does anyone have an idea how I can ensure that the contents of the form fields are retained when merging the pages?

Thanks in advance for your help!
