Using the code below, I\'m trying to get all the fields and their values, but it\'s only returning the field values. What do I need to do to get both?

Answer 1

To get all the fields and their values with iText:

// you only need a PdfStamper if you're going to change the existing PDF.
PdfReader reader = new PdfReader( pdfPath );

AcroFields fields = reader.getAcroFields();

Set<String> fldNames = fields.getFields().keySet();

for (String fldName : fldNames) {
  System.out.println( fldName + ": " + fields.getField( fldName ) );
}

Beyond that, it would help if we could see a PDF that is giving you trouble.

Answer 2

Here's the answer updated for iText version 7.0.2:

PdfReader reader = new PdfReader( pdfPath );
PdfDocument document = new PdfDocument(reader);
PdfAcroForm acroForm = PdfAcroForm.getAcroForm(document, false);
Map<String,PdfFormField> fields = acroForm.getFormFields();
for (String fldName : fields.keySet()) {
  System.out.println( fldName + ": " + fields.get( fldName ).getValueAsString() );
}
document.close();
reader.close();
