Reduce Redundancy: Pre-Fill Laserfiche Forms from Prior Data

Introduction:  When external forms need to be reviewed and corrected, asking users to re-enter the same information can slow the process and increase the risk of errors—especially with long, data-heavy forms. This solution enables Laserfiche Forms to repopulate fields from a previous submission, allowing external users to make necessary updates without starting over. It also streamlines internal-to-external handoffs by preserving entered data, minimizing lookups, and maintaining continuity across revisions, so teams can collaborate efficiently without losing information.

Test Version: Laserfiche Forms Professional Version 11.0.2311.50564 and above

Repopulate Form Fields from Previous Submission - Modern Designer

1. Add any Basic Field to your form.

This can be a Single Line, Checkbox, Currency, Date, or any other basic field type.

2. Add two Multi-line fields to your form.

Identify these fields as shown in the example.

3. Apply the CSS class skip to both Multi-line fields.

This prevents the fields from being included in the data capture.

4. Insert the Day 17 JavaScript into the form’s JavaScript editor to enable field data capture and array usage.

5. Production usage note.

In a live environment, store the JSON Field Collection data in a SQL database and use a Lookup Rule to populate the JSON Field Array based on a parameter. This approach supports passing external forms back and forth while preserving field responses.
