Precognition

Precognition enables real-time field validation as users type, providing immediate feedback without requiring a full form submission. This feature is only available when using HTMX mode.

Prerequisites

1. HTMX Mode: Your form must use HTMX mode
2. Idiomorph Extension: Required for DOM morphing

Install HTMX and the Idiomorph extension.

Configuration

Enable precognition in your config:

// site/config/config.php

return [
  'tobimori.dreamform' => [
    'mode' => 'htmx',
    'precognition' => true,
  ],
];

How It Works

• Fields validate automatically as users type or change values
• Text fields wait 500ms after typing stops before validating
• Select/radio/checkbox fields validate immediately on change
• Only the changed field is validated, not the entire form
• No data is saved during precognitive validation

Partial Submissions

When precognition is enabled, you can also enable partial submissions:

// site/config/config.php

return [
  'tobimori.dreamform' => [
  	// ...
    'partialSubmissions' => true,
  ],
];

This automatically saves each field's value as the user fills it out. This helps track progress for abandoned forms and prevents data loss from failed submissions.
