Device & OS

Scenario
Creating an interactive PDF form designed to let users easily fill, save, and email their completed submissions via a single button click.
Observed behavior
Strict security restrictions prevent a PDF from silently saving directly to a user's computer, stopping the automated workflow from functioning without trusted local scripts.
Before you start

Before configuring your interactive buttons, be aware that modern PDF readers block silent background saving to protect users from malicious scripts. You will need to rely on explicit user prompts to save the file.

Solution 1Recommended

Trigger a 'Save As' Prompt Before Email Submission

Use JavaScript to prompt the user with a 'Save As' dialog manually before initiating the email submission process.

Due to security sandboxing, PDFs cannot automatically write files to a user's hard drive unless a trusted folder-level script is installed locally. The standard workaround is to script the button to open the 'Save As' dialog, forcing the user to save it before the email opens.

1
Add a button to the PDF form

Open your PDF in form editing mode, select the Button tool from the interactive objects menu, and draw a button on your document.

2
Access the button's action properties

Right-click the newly created button, select 'Properties', and navigate to the 'Actions' tab.

3
Add a JavaScript action

In the 'Select Action' dropdown, choose 'Run a JavaScript' and click the 'Add' button to open the JavaScript editor.

4
Input the script

Enter a script that first executes the Save As menu item (e.g., using app.execMenuItem("SaveAs")) and then calls the this.mailDoc() method to generate the email attachment.

Trigger a 'Save As' Prompt Before Email Submission
Enforcing the Save Action: You can add conditional logic to your script to check if the file path has changed or if the document is 'dirty' (unsaved) to prevent the email function from triggering until the save is confirmed.

Frequently Asked Questions

Why can't my PDF automatically save without prompting the user?

Modern PDF viewers implement strict security sandboxing to prevent malicious files from writing data to your hard drive without your explicit permission. Silent saving requires a trusted, locally installed script.

Can I force a user to save the PDF before they click the email submit button?

Yes, you can use JavaScript attached to the button to check the document's save status. If the file is unsaved or modified, the script can halt the email submission and trigger a 'Save As' dialog instead.

How do I submit a PDF form via email without using JavaScript?

You can use a standard Submit Form action in your button properties. Set the action to 'Submit a form' and enter a 'mailto:' URL (e.g., mailto:email@example.com). This will attach the raw form data or the PDF to an email draft, though it will not automatically save the file locally.
