Hi, I'm new to grav and i created a simple plugin for additional form validation.
This works fine so far, but when a validation error occurs and $event->stopPropagation() is called
only the next form action in the series will be stopped instead of all.
This means in my example below, the Email won't be sent but the page will be redirected.
Is this the right behavior or is something wrong within the plugin?
Form frontmatter:
YAML
process:
- validate: validate
- email:
from: "{{ form.value.email }}"
to: "{{ config.plugins.email.to }}"
subject: "Contact"
body: "{% include 'forms/mail.html.twig' %}"
- redirect: contact/thankyou
Plugin code:
PHP
<?php
namespace Grav\Plugin;
use Grav\Common\Plugin;
use RocketTheme\Toolbox\Event\Event;
class ValidationPlugin extends Plugin{
public static function getSubscribedEvents() {
return [
'onFormProcessed' => ['onFormProcessed', 0]
];
}
public function onFormProcessed(Event $event){
$form = $event['form'];
$action = $event['action'];
$params = $event['params'];
switch ($action) {
case 'validate':
$arrPost = $form->value()->toArray();
$errCount = 0;
if ($arrPost['json'] != "an" || !empty($arrPost['website']) || !empty($arrPost['mail']) || $arrPost['form-id']!=$form->name){
$errCount++;
$errMsg[] = $this->grav['language']->translate('FORM.VALIDATION_FAIL', null, true) . $this->grav['language']->translate('PLUGIN_VALIDATION.ERROR_BOT');
}
if (isset($arrPost['schash']) && $arrPost['schash'] != md5($arrPost[$arrPost['scfield']])){
$errCount++;
$errMsg[] = $this->grav['language']->translate('FORM.VALIDATION_FAIL', null, true) . $this->grav['language']->translate('PLUGIN_VALIDATION.ERROR_SC');
}
if($errCount > 0){
$this->grav->fireEvent('onFormValidationError', new Event(['form' => $form, 'message' => implode('<br>',$errMsg)]));
$event->stopPropagation();
return;
}
break;
}
}
}
