civi.afform.get

Summary

This Symfony event allows developers to register or modify Afforms programmatically. It is dispatched during the Afform APIv4 get action.

Definition

This event is dispatched via the Symfony EventDispatcher.

public static function onAfformGet(\Civi\Core\Event\GenericHookEvent $event): void

Parameters

  • \Civi\Core\Event\GenericHookEvent $event

Event Properties

Since this event uses GenericHookEvent, properties are accessed dynamically:

  • $event->afforms: array - A reference to the array of Afform definitions, keyed by form name. Alterable.
  • $event->getNames: array - Filters for names requested by the API (includes name, module_name, directive_name). Used for optimization.
  • $event->getTypes: array - Filters for types of Afforms requested by the API. Used for optimization.
  • $event->getLayout: bool - Indicates if the API request expects the layout (HTML markup) of the form to be returned. Used for optimization.

Example

use Civi\Core\Event\GenericHookEvent;

public static function onAfformGet(GenericHookEvent $event): void {
  $getNames = $event->getNames;

  // Optimize: Only generate if our specific form is requested (or if no name filter is applied)
  if (isset($getNames['name']) && !in_array('myCustomAfform', $getNames['name'])) {
    return;
  }

  $event->afforms['myCustomAfform'] = [
    'name' => 'myCustomAfform',
    'type' => 'form',
    'title' => ts('My Programmatic Afform'),
    'description' => ts('This form was generated dynamically by an event listener.'),
    'icon' => 'fa-cog',
    'permission' => ['access CiviCRM'],
  ];

  if ($event->getLayout) {
    $event->afforms['myCustomAfform']['layout'] = '<div><h3>My Form</h3><af-field name="first_name" /></div>';
  }
}
