PAC Form Bridge connects Formidable Forms Free to Claris FileMaker.

Formidable validates and saves the entry first. PAC Form Bridge then sends every supported value to the FileMaker Main Script configured for that form.

There is no field mapping. Each value includes its numeric field ID and logical field key.

What the Free edition does

Uses the standard Formidable Forms submission workflow.
Sends all supported saved field values to one Main Script.
Keeps connection settings separate for each form.
Supports private FileMaker hostnames and IPs over verified HTTPS.
Encrypts the FileMaker password with keys derived from the WordPress authentication salts.
Tests the Data API connection without running the Main Script.
Reports whether FileMaker confirmed the delivery.
Keeps minimal diagnostics for the most recent connection test and delivery.

Supported Formidable field values

Text, Paragraph, Checkboxes, Radio, Dropdown, Email, URL, Number, Name, Phone, Hidden, User ID, Address, GDPR consent, Product, Quantity and Total are supported.

Empty and compound values retain their JSON structure. Values come from the saved entry. Product, Quantity and Total data is not proof of payment.

Deliberate Free edition limits

The Free edition performs one final data delivery. It does not:

Transfer files or file references.
Send password fields or payment credentials.
Process nested forms, repeaters or unsupported custom fields.
Call FileMaker when the form opens or while a field is being edited.
Add PAC-specific buttons or fields.
Let FileMaker change field values, choices, visibility or enabled state.
Execute response actions, redirects or remote HTML.
Retry a failed or uncertain delivery automatically.

PAC Form Bridge Professional is a separate distribution for live FileMaker-driven forms, interactions, uploads and response actions. Its code is not included in Free.

PAC Form Bridge Professional

Professional turns a Formidable form into a live FileMaker-driven interface. In addition to final submission, it can:

Call FileMaker when the form opens and when configured field events occur.
Populate fields and choices from FileMaker responses.
Change field visibility and enabled state dynamically.
Provide PAC action buttons for additional FileMaker interactions.
Upload files to FileMaker Container fields.
Apply ordered response actions returned by FileMaker.

Professional remains designed around Formidable Forms Free. Free and Professional use the same plugin folder, so upgrading replaces the Free edition while preserving the distinction between the two products.

See PAC Form Bridge features and licensing or read the documentation.

Requirements

WordPress 6.4 or newer.
PHP 7.4 or newer with Sodium or OpenSSL available for password encryption.
Formidable Forms, free edition or newer.
A reachable FileMaker Server with the Data API enabled.
A FileMaker account with the fmrest extended privilege, plus an accessible layout and Main Script.

FileMaker Server, hosting and any applicable Claris licensing are not included with this plugin.

FileMaker Script Contract

The Main Script receives a JSON object in Get ( ScriptParameter ):

{"protocol":"pac-form-bridge/1","request_id":"a-unique-request-id","form":{"id":12,"key":"contact"},"entry":{"id":42},"event":{"name":"button","role":"final","source":"submit"},"fields":[{"id":103,"key":"email","value":"[email protected]"}]}

Use each field item’s key property, which contains the Formidable field_key. Array positions are not a stable mapping.

After accepting and committing the data, the Main Script must return a JSON object with a Boolean success value:

{"success":true}

To reject the delivery, return:

{"success":false}

Use JSON Booleans, not strings. Free ignores response actions, messages, HTML and URLs.

The request ID identifies one attempt. Implement any persistent duplicate protection required by your integration in FileMaker.

Delivery Behavior

PAC Form Bridge sends data only after Formidable creates a new, validated frontend entry. It does not send when validation fails or when an entry is a draft, spam, child entry, edit, import or isolated programmatic creation.

When FileMaker returns {"success":true}, the normal Formidable success message remains visible and PAC adds a delivery confirmation.

When FileMaker does not confirm the delivery:

The Formidable entry remains saved.
Normal Formidable actions that already ran are not rolled back.
A warning replaces the normal success confirmation.
A redirect confirmation is suppressed for that submission.
No automatic retry occurs.

WordPress and FileMaker do not share a transaction. A timeout can occur after FileMaker processed the request. Check the entry, request ID and FileMaker before recovery. Exactly-once delivery is not guaranteed.

Privacy and External Services

PAC Form Bridge uses two external services:

The administrator-configured FileMaker Server receives form data only when delivery is enabled, as described below.
The bundled Freemius SDK presents an optional opt-in to help improve the plugin. If an administrator accepts, Freemius receives the data and permissions shown on that consent screen. Skipping opt-in does not disable the plugin. PAC Form Bridge never sends submitted form values or FileMaker credentials to Freemius.

Freemius service: https://freemius.com/
Terms: https://freemius.com/terms/
Privacy policy: https://freemius.com/privacy/

Delivery is disabled until an administrator enables it. An enabled submission sends supported saved values, form ID/key, entry ID, event metadata and request ID. The connection test sends credentials only to create and close a Data API session; it sends no form values and runs no script.

The FileMaker password is encrypted in WordPress. Diagnostics never store submitted values, passwords, authorization headers, tokens or complete response bodies.

The site owner or its provider operates FileMaker. Their terms, privacy policy, retention and legal basis apply. Administrators must inform visitors about the transfer and configure their privacy policy as required.

Support and Scope

Support covers this plugin and its documented delivery behavior. It excludes FileMaker solution design, server administration, recovery, certificates, networks and hosting.

For support, include plugin, WordPress and Formidable versions plus the last diagnostic. Never publish credentials or tokens.
