Formie provides a collection of events for extending its functionality. Modules and plugins can register event listeners, typically in their init() methods, to modify Formie’s behavior.

Form Events#

The beforeSaveForm event#

The event that is triggered before a form is saved. You can set $event->isValid to false to prevent saving.

use craft\events\ModelEvent;

    $fieldValues = $event->fieldValues;
    $submission = $event->submission;
    $fieldMapping = $event->fieldMapping;
    $fieldSettings = $event->fieldSettings;
    $integration = $event->integration;
});

use verbb\formie\controllers\IntegrationsController;
use verbb\formie\events\OauthTokenEvent;

    $token = $event->token;
    // ...
});

The beforeSaveToken event#

The event that is triggered before an integration token is saved.

use verbb\formie\events\TokenEvent;
use verbb\formie\services\Tokens;

    $isNew = $event->isNew;
    // ...
});

    $isNew = $event->isNew;
    // ...
});

use verbb\formie\events\TokenEvent;
use verbb\formie\services\Tokens;
use yii\base\Event;

    $token = $event->token;
    // ...
});

    $token = $event->token;
    // ...
});

Address Provider Integration Events#

The modifyAddressProviderHtml event#

The event that is triggered after an address provider has its HTML generated. You are able to modify its HTML.

use verbb\formie\events\ModifyAddressProviderHtmlEvent;
use verbb\formie\integrations\addressproviders\AddressFinder;
use yii\base\Event;

Event::on(AddressFinder::class, AddressFinder::EVENT_MODIFY_ADDRESS_PROVIDER_HTML, function(ModifyAddressProviderHtmlEvent $event) {
    $html = $event->html;
    // ...
});

Microsoft Dynamics 365 Events#

The modifyRequiredLevels event#

The event that is triggered to allow modification of the fields that are marked as required during field mapping in the model.

Microsoft Dynamics 365 has four AttributeRequiredLevel values (opens new window). By default SystemRequired and ApplicationRequired fields will be marked as mandatory in the field mapping model. You can override this, by passing a specific array of values.

You should always provide at minimum SystemRequired fields to avoid API errors. ApplicationRequired values can technically be bypassed through the API, but will be defined as Business Rules within Microsoft Dynamics 365. You can also do the reverse and also force Recommended values, however this will usually require a lot of unnecessary fields to be mapped.

use verbb\formie\events\MicrosoftDynamics365RequiredLevelsEvent;
use verbb\formie\integrations\crm\MicrosoftDynamics365;
use yii\base\Event;

Event::on(MicrosoftDynamics365::class, MicrosoftDynamics365::EVENT_MODIFY_REQUIRED_LEVELS, function(MicrosoftDynamics365RequiredLevelsEvent $event) {
    // Set required level to SystemRequired only
    $event->requiredLevels = ['SystemRequired'];
});

The modifyTargetSchemas event#

The event that is triggered to allow modification of the target schemas when populating lookup/relational fields.

Formie populates lookup/relational field values of the common standard entities, but this event gives you a chance to modify the standard entities along with populating any custom entities in the mapping.

Any modifications made to the standard entities such as systemuser or campaign will be merged and overwritten with the values from the event.

The following additional parameters are available for each entity:

  • expand - For more complex queries related to one or more entities
  • filter - Specify a filter to modify the returned values
  • limit - Set the amount of values to return (defaults to 100 if not specifically set)
  • orderby - Order the returned values by a specific criteria e.g. name asc

When using the limit option. Be mindful of the performance impact when refreshing the integration.

use verbb\formie\events\MicrosoftDynamics365TargetSchemasEvent;
use verbb\formie\integrations\crm\MicrosoftDynamics365;
use yii\base\Event;

Event::on(MicrosoftDynamics365::class, MicrosoftDynamics365::EVENT_MODIFY_TARGET_SCHEMAS, function(MicrosoftDynamics365TargetSchemasEvent $event) {
    $event->targetSchemas = [
        'systemuser' => [
            // Filter to modify the returned values
            'filter' => 'isdisabled eq false and invitestatuscode eq 4 or accessmode eq 4',
        ],
        // Set the order to be something more logical for this entity and allow more than 100 values
        'campaign' => [
            'orderby' => 'createdon desc',
            'limit' => '150'
        ],
        // A custom entity
        'ccl1000_enquirytype' => [
            'entity' => 'ccl1000_enquirytypes',
            'label' => 'ccl1000_name',

        ]
    ];
});

The event that is triggered during a migration (from Sprout Forms or Freeform), trying to map the respective third-party field to a Formie field. The field variable represents the Sprout Forms or Freeform field, and newField represents the Formie equivalent field.

You can use this event to custom Sprout Forms or Freeform field to a field Formie can understand.

use verbb\formie\events\ModifyMigrationFieldEvent;
