How to add custom validate for post

oanhnn

I need make custom validates for comment post (reply).

   /**
     * @param Dispatcher $events
     */
    public function subscribe(Dispatcher $events)
    {
        $events->listen(ConfigureValidator::class, [$this, 'addValidate']);
    }

    public function addValidate(ConfigureValidator $event)
    {
        // TODO:
    }

Please help me.

oanhnn the ConfigureValidator has two properties:

type
validator

You can add new rules by using the second one:

if ($event->type instanceof \Flarum\Core\Validator\PostValidator) {
    $event->validator->mergeRules('content', [
        'min:100'
    ]);
}

The above will add the minimum requirement of 100 characters for posts.

disclaimer; untested ?

luceos This rule validates the length of the post post-parsing (e.g. if you set min to 5, 1 is parsed to <t><p>1</p></t>, which is greater than 5 chars), is there a rule for the pre-parsing length?

If someone stumbles on this years later, ConfigureValidator doesn't exist anymore.
Use $events->listen(Validating::class, [$this, '']); instead.
