- Device & OS
- not provided
- Scenario
- Creating an interactive form with a multi-step completion and approval process.
- Observed behavior
- The goal is to allow initial data entry, restrict subsequent editing, and enable authorized approval directly on the document securely.
Ensure you have a professional PDF editor installed, as setting up interactive form fields and configuring digital signature workflows requires advanced PDF editing tools.
Use Digital Signatures and Read-Only Configurations
Set up your interactive PDF to lock form fields automatically after submission or approval to ensure document integrity.
While a simple approval checkbox can be used, a genuine digital signature provides much stronger cryptographic validation for approval workflows. It ensures the document cannot be tampered with after the director signs it.
Open your PDF form editor and add the necessary text fields, checkboxes, and date fields for the employee to fill out their request.
Insert a Digital Signature field specifically designated for the director's approval or rejection action.
Right-click the Digital Signature field, open its Properties, and navigate to the 'Signed' tab. Select the option to mark 'All fields' or 'Specific fields' as read-only once the signature is applied.
Save the form and send it to employees. After an employee fills it out, the director can review the document, click the signature field to apply their digital ID, and lock the document.

Frequently Asked Questions
How can I prevent users from changing the form data after approval?
You can configure the digital signature field properties so that upon signing, all or specific form fields are automatically locked and marked as read-only.
Can I just use a checkbox for approval instead of a digital signature?
