Subject: After Merging, form fields are lost
Date Posted: 05 Jan 06 at 8:20AM
I'm trying to merge several PDF files with empty form fields (templates) into a single one.
It happens that after the merging process, the form fields are lost. Only the form fields of the firstly added file are left.
My guess is this is a bug on QuickPDF itself.
I inserted below a VBScript that shows the problem.
What do I need after all ?
I need to add several templates, that is PDFs with form fields, each one corresponding to a page. Then I need to substitute each field content with data. Of course, I need to substitute ALL of the fields, from all the pages. I can do this substitution process either doing it page per page, that is replacing the fields while I add the pages, or at once, at the end of the merging process. But I do need to replace ALL of the fields.
Finally, here's the script :
---------------------------------------------------
OPTION EXPLICIT
DIM objPDF1,objPDF2,objPDF3,lni,mykey
mykey="mykey"
Set objPDF1 = WScript.CreateObject("ISED.QUICKPDF")
WScript.Echo objPDF1.LibraryVersion
WScript.Echo "UnlockKey ",objPDF1.unlockkey(mykey)
WScript.Echo "Load File A ",objPDF1.LoadFromFile("FILEA.PDF")
'You may get a copy of this template from here : 'http://www.DES.online.unimep.br/au/FILEA.PDF
for lni=1 to objPDF1.FormFieldCount
WScript.Echo "Field #",lni," from A ",objPDF1.GetFormFieldTitle(lni)
next
WScript.Echo "Load File B ",objPDF1.LoadFromFile("FILEB.PDF")
'You may get a copy of this template from here : 'http://www.DES.online.unimep.br/au/FILEB.PDF
for lni=1 to objPDF1.FormFieldCount
WScript.Echo "Field #",lni," from B ",objPDF1.GetFormFieldTitle(lni)
next
WScript.Echo "***SO FAR SO GOOD ! FILES ARE LOADED OK AND FIELDS DISPLAYED AS EXPECTED"
WScript.Echo "------------------------------------------------------------------------"
' LET THE PROBLEMS BEGIN NOW BY MERGING BOTH FILES...
Set objPDF2 = WScript.CreateObject("ISED.QUICKPDF")
WScript.Echo "UnlockKey ",objPDF2.unlockkey(mykey)
WScript.Echo "Add File A",objPDF2.AddToFileList("mfl","FILEA.PDF")
WScript.Echo "Add File B",objPDF2.AddToFileList("mfl","FILEB.PDF")
WScript.Echo "Merge to C",objPDF2.MergeFileList("mfl","FILEC.PDF")
WScript.Echo "Clear ",objPDF2.ClearFileList("mfl")
WScript.Echo "***MERGING PROCESS HAS BEEN COMPLETED OK..."
WScript.Echo "------------------------------------------------------------------------"
Set objPDF3 = WScript.CreateObject("ISED.QUICKPDF")
WScript.Echo "UnlockKey ",objPDF3.unlockkey(mykey)
WScript.Echo "Load File C ",objPDF3.LoadFromFile("FILEC.PDF")
WScript.Echo "Field Count C ",objPDF3.FormFieldCount
for lni=1 to objPDF3.FormFieldCount
WScript.Echo "Field #",lni," from A ",objPDF3.GetFormFieldTitle(lni)
next
WScript.Echo "***OPS - WHERE ARE THE FORM FIELDS FROM FILE B ?"
When I execute the script above on my machine, it says :
5.11
UnlockKey 1
Load File A 1
Field # 1 from A FIELD1FROMFILEA
Load File B 1
Field # 1 from B FIELD1FROMFILEB
Field # 2 from B FIELD2FROMFILEB
***SO FAR SO GOOD ! FILES ARE LOADED OK AND FIELDS DISPLAYED AS EXPECTED
------------------------------------------------------------------------
UnlockKey 1
Add File A 1
Add File B 1
Merge to C 2
Clear 1
***MERGING PROCESS HAS BEEN COMPLETED OK...
------------------------------------------------------------------------
UnlockKey 1
Load File C 1
Field Count C 1
Field # 1 from A FIELD1FROMFILEA
***OPS - WHERE ARE THE FORM FIELDS FROM FILE B ?

Hi!
Have this behavior something to do with documents and files? You know the library offers functions like DocumentCount and DocumentID. I think your new file has two documents and you have to select (one after the other) the two documents and document for document you can work with your formfields...
I don't know if it's so ... i think it's so ;-)

Cheers,
Ingo

Hi Ingo
Thanks again 4 your support !
I had thought about this before and had also unsucessfully tried it.
Anyway, I tried it again, in another way and now it's WORKING !
Below is another script, which is working.
What I disliked :
- I had to delete page # 1 because it is a blank page
- I'm afraid that the performance may not be so nice
The Script, after all :
OPTION EXPLICIT
DIM objPDF,docFinalPDF,docPDF2beMerged,lni
Set objPDF = WScript.CreateObject("ISED.QUICKPDF")
WScript.Echo "UnlockKey ",objPDF.unlockkey("mykey")
docFinalPDF=objPDF.NewDocument()
WScript.Echo "New ",docFinalPDF
WScript.Echo "Load File ",objPDF.LoadFromFile("FILEA.PDF")
docPDF2beMerged=objPDF.DocumentID(3)
WScript.Echo "doc id M ",docPDF2beMerged
WScript.Echo "field CNT ",objPDF.FormFieldCount
for lni=1 to objPDF.FormFieldCount
WScript.Echo objPDF.GetFormFieldTitle(lni)
next
WScript.Echo "set form f",objPDF.SetFormFieldValueByTitle("FIELD1FROMFILEA","*field1fromfilea*")
WScript.Echo "Selected ",objPDF.SelectDocument(docFinalPDF)
WScript.Echo "Merge ",objPDF.MergeDocument(docPDF2beMerged)
WScript.Echo "Load File ",objPDF.LoadFromFile("FILEB.PDF")
docPDF2beMerged=objPDF.DocumentID(3)
WScript.Echo "doc id M ",docPDF2beMerged
WScript.Echo "field CNT ",objPDF.FormFieldCount
for lni=1 to objPDF.FormFieldCount
WScript.Echo objPDF.GetFormFieldTitle(lni)
next
WScript.Echo "set form f",objPDF.SetFormFieldValueByTitle("FIELD1FROMFILEB","*field1fromfileb*")
WScript.Echo "set form f",objPDF.SetFormFieldValueByTitle("FIELD2FROMFILEB","*field2fromfileb*")
WScript.Echo "Selected ",objPDF.SelectDocument(docFinalPDF)
WScript.Echo "Merge ",objPDF.MergeDocument(docPDF2beMerged)
WScript.Echo "Deletepage",objPDF.DeletePages(1,1)
WScript.Echo "save ",objPDF.SaveToFile("C:\TEMP\TEST.PDF")
