• Frontend Button Visibility: Hide buttons for unauthorized users

Form Configuration

• Secure All Forms Automatically: If enabled, all your JetFormBuilder forms files will be secured

Debugging (optional)

Logs will be written to the WordPress debug log. 

Note: Keep this setting disabled unless you run into issues and want to check the logs.

Uploading Documents Securely with JetFormBuilder:

1. Build or edit a JetFormBuilder form that includes file upload fields. Please check JetFormBuilder section on how to correctly set your media fields.
2. Pick the form from the list if or you're set if you have turned on auto-protection.
3. Users fill and submit the form.
4. Uploaded files are automatically protected and replaced with safe references.

Showing Secure Files in JetEngine Listings:

Add a Dynamic Field widget to your listing template.

For normal fields:

Source - Meta Data

Meta Field - Select your media field from the dropdown.

Scroll down and toggle filter field output switcher on. Select Secure File Links in the callback dropdown. That's it!

For repeater fields:

The steps are almost similar to those of normal fields, but with a slight difference.

Source - Meta Data

Meta Field - Leave empty and instead, add your repeater field name in the object field/meta field/repeater key/component prop input field. See screenshot below.

Scroll down and toggle filter field output switcher on. Select Secure File Links in the callback dropdown. Toggle this is a repeater field switcher and choose your repeater layout (table/cards).

Styling Buttons, Tables, and Cards

Buttons:

Button style controls are available for both normal and repeater fields the moment you choose Secure File Links callback.

Table:

Table styling controls are available conditionally, that is, if you choose your repeater layout as table.

Cards:

Cards styling controls are also available if you set your repeater layout to cards.

Adjust styles for buttons, cards, or tables as desired.

You can make other button adjustments from here such as hidding view/download buttons, change button text, etc.

Below is how you should configure your JetFormBuilder (JFB) form media field. Follow the same for forms with presets.

User Access: set this based on your use case. Setting it to any registered user should work in many cases.

Enable insert attachment and note that it only works for logged-in users. 

Configure the rest based on your preferences.

Common Issues and Fixes:

- Files Aren't Getting Protected: Check form ID or auto-secure setting.

- Links Don't Work: Ensure correct user access or clear cache.

- Files Visible in Media Library: Check for custom query overrides.

- Repeater Displays Wrong Labels: Confirm JetEngine meta fields.

- Permission Denied on Downloads: Verify folder permissions.

- Slow Uploads or Timeouts: Increase PHP upload limits.

- Plugin Conflicts: Update JetFormBuilder and JetEngine.
