# 5.5 One-round signing with PDF with signature acrofields

In this example the PDF document has already been inserted:

- Signature acrofields
- Other active elements, like
  - Text field
  - Date field

  - Check box

There is no need to set the state of the document to “tags” in *filedata array*, because the document already contains signature acrofields. The state of the document should be set to “tosgin”.

For this example, one-round signing there is no need to define which signature field should be available = they all are available.

OKdokument API provides functionality to pre-filled active elements. This is done via array *fieldConfig*. In our example values:

- firstName, lastName – are pre-filled, signer can change them
- date – is pre*filled, signer can’t change the value of the date
- checkBox1 – is checked, signer can’t uncheck it

Note: name of the active elements must be the same as in the PDF (technical name of the acrofield)
