FormFlow is a WordPress plugin that extends Contact Form 7 with event registration management. It allows administrators to create events, manage registration batches, automatically handle waiting lists, and monitor registrations from the WordPress dashboard.

The plugin is designed for organizations that run recurring events where registrations are limited by capacity.

Features

Event Management

• Create and manage events
• Connect an event to a Contact Form 7 form
• Enable or disable waiting lists
• Prevent duplicate Contact Form assignments

Batch-Based Registration

Each event can contain multiple batches.

Each batch supports:

• Capacity limits
• Open
• Closed
• Completed
• Cancelled

Only one batch can be open at a time.

Automatic Waiting List

If an event has:

• no active batch
• or the active batch is full

registrations are automatically placed on the waiting list instead of being rejected.

When a new batch is opened:

• waiting registrations are promoted automatically
• oldest registrations are promoted first
• promotion continues until capacity is reached

Contact Form 7 Integration

FormFlow integrates directly with Contact Form 7.

Supported features:

• Uses native CF7 validation
• Uses native success message for confirmed registrations
• Displays a custom success message for waiting list registrations
• Stores the complete submitted form data

• Waiting List confirmation
• Registration promotion confirmation

Email recipients are detected automatically from the Contact Form.
