CMB SQLite Form is a lightweight yet powerful contact form solution designed for performance and privacy. Unlike traditional form plugins that clutter your main WordPress database, this plugin stores all submissions in a secure, local SQLite database.

It features a robust Global vs. Per-Form Settings system, allowing you to configure defaults once and override them only when needed for specific forms.

Configuration

Global vs. Form Settings

The plugin uses a smart inheritance system:
1. Global Settings: Define the default behavior for ALL forms (e.g., your SMTP server, default styling, admin email).
2. Form Settings: When editing a specific form, you can toggle “Override Global Settings” on any section to customize it just for that form.

Setting up Bot Protection

  1. Go to Global Settings > Bot Protection.
  2. Enable Honeypot (recommended).
  3. Enable Time Validation (e.g., set to 3 seconds).
  4. (Optional) Enable CAPTCHA for stricter forms.

Configuring Email Sending

You can choose how emails are sent:
* WordPress Default: Uses your server’s standard PHP mail() function.
* Custom SMTP: Go to Notifications > Outgoing Server to configure a specific SMTP server (Gmail, SendGrid, etc.) for reliable delivery.
