Custom Validation #

You can add custom validation to field, to handle all manner of scenarios. To do this, you'll need to create a custom module to contain PHP code for the validation logic.

Make sure you’re comfortable creating a plugin or module for Craft CMS. Take a look at this Knowledge Base article for a complete example.

If you write your own plugin or module, you’ll want to use its init() method to subscribe to an event on the Submission object to add your validation rules. Your event listener can add additional validation rules for fields.

For example, let's say we have a field with a handle emailAddress which we'd like required. We could do this with the following.

use verbb\formie\elements\Submission;
use verbb\formie\events\SubmissionRulesEvent;
use yii\base\Event;

Event::on(Submission::class, Submission::EVENT_DEFINE_RULES, function(SubmissionRulesEvent $event) {
    $event->rules[] = [['field:emailAddress'], 'required'];
});

Or, maybe we only want a field required when another field is a certain value.

Event::on(Submission::class, Submission::EVENT_DEFINE_RULES, function(SubmissionRulesEvent $event) {
    $event->rules[] = [['field:emailAddress'], 'required', 'when' => function($model) {
        return $model->subscribeMe;
    }]];
});

Here, we check if a field with handle subscribeMe is truthy, and if so make the emailAddress field required.

Another example could be limiting a field to be numeric, and a maximum length.

Event::on(Submission::class, Submission::EVENT_DEFINE_RULES, function(SubmissionRulesEvent $event) {
    $event->rules[] = [[‘field:accountNumber'], 'number', 'integerOnly' => true, ‘max’ => 9];
});
