Fill PDF Form Fields Programmatically in React Native

PSPDFKit for React Native allows you to fill form fields programmatically. Each form field has a fully qualified name used to identify and retrieve a specific form field object before filling it.

Getting the Fully Qualified Name of a Form Field

The example below shows how to obtain the fully qualified name of the first form field on the first page of a document:

let annotations = await this.refs.pdfView.getAnnotations(0, 'all');
let firstFormFieldName = annotations[0]['formFieldName'];

Filling the Value of a Form Field

The example below shows how to fill the value of a form field with a fully qualified name (formFieldName) and two radio buttons with fully qualified names (radioFieldName_0 and radioFieldName_1):

	'Form Field Value',

// For radio buttons and checkboxes, use `selected` and `deselected`.
this.refs.pdfView.setFormFieldValue('radioFieldName_0', 'selected');
this.refs.pdfView.setFormFieldValue('radioFieldName_1', 'deselected');
