Settings Hooks and Events

The Settings module exposes a single filter used to register and discover settings definitions from anywhere in your application or packages.

Filters

ap.settings.registeredSettings

• Type: filter
• Purpose: Provide and aggregate settings definitions
• Signature: applyFilters('ap.settings.registeredSettings', array $settings): array

Each entry in the array should be keyed by the setting key and contain:

[
    'default'  => mixed,     // Default value for reads when not stored
    'type'     => string,    // 'string' | 'boolean' | 'integer' | 'float' | 'json'
    'callback' => callable,  // Sanitizer used on update
]

Example: Register via Filter

While the preferred way is using apRegisterSetting() or SettingsManager::registerSetting(), you can also contribute directly via the filter if needed:

addFilter('ap.settings.registeredSettings', function (array $settings) {
    $settings['site.tagline'] = [
        'default'  => 'Just another site',
        'type'     => 'string',
        'callback' => fn ($value) => trim((string) $value),
    ];

    return $settings;
});
