Question details
The user wants to populate matching form fields on multiple PDF pages based on a value entered on the first page, initially asking for an Acrobat JavaScript solution.
- Product

- Device & OS
- not provided
- Scenario
- Creating a multi-page PDF form where the same user data, such as a name or age, needs to appear consistently on several different pages.
- Observed behavior
- The user wants to automate data entry across the document so that typing a value once instantly fills all corresponding fields.
Ensure your PDF document is open in form-editing mode and identify the exact pages and locations where the duplicated field values need to appear.
Use Identical Field Names (No JavaScript Required)
You do not need to write complex JavaScript to duplicate form data. Simply assigning the exact same fully qualified name to multiple fields links them automatically.
In standard PDF forms, when two or more text fields share the exact same name, the software treats them as instances of a single field. Any data entered into one instance will instantly reflect in all other instances across the document.
Launch your PDF editor and enter the Form editing mode to access your document's interactive fields.
Select the text field tool, draw your primary form field on the first page, and open its Properties menu.
In the General tab of the Properties menu, name the field with a specific identifier, such as 'Age' or 'ClientName'.
Navigate to the other pages where you want this data to appear, and draw new text fields in those locations.
Open the Properties for these new fields and assign them the exact same name ('Age' or 'ClientName') as the primary field. Save your document.

Frequently Asked Questions
Does this identical-name trick work for dropdowns and checkboxes?
Yes. If you assign the same name to multiple checkboxes or dropdown menus in a PDF form, making a selection in one will automatically mirror the selection in the others.
Why are my PDF fields not updating automatically across pages?
Ensure that the field names are absolutely identical, including case sensitivity. For example, 'Age' and 'age' are treated as completely different fields in PDF forms and will not share data.
Can I still use JavaScript if I want to manipulate the copied data?
Yes. While identical names are best for direct 1-to-1 copying, you can use Acrobat JavaScript in the custom calculation script of a target field if you need to perform math, combine text, or format the duplicated data differently from the source field.
