Minimum Post Character Length

LiamKenyon

Apologies if this is already posted I’ve searched and can’t find anything relating apart from an unsupported Limit extension.

Is there a way via either an extension or code in extend.php to create a minimum length a post is allowed to be?

It’s to try stop spam/short posts of “ty, thanks, etc…”

Thanks.

LiamKenyon I think you should extend the PostValidator class adding the minimum length rule. You can take a look at this extension which replaces the discussion title length.

Just bumping this to see if anyone has any ideas.

Matteo thanks for your response I will take a look at it.

Been also reviewing this thread/code also - https://discuss.flarum.org/d/32688-limit-post-length which creates a limit on max characters so going to play about with the both and see what I can come up with.

I ended up using the following code in extend.php file.

Not sure if its the best way or not.

use Flarum\Extend;
use Flarum\Post\Event\Saving;
use Flarum\Post\Exception\InvalidPostException;
use Flarum\User\User;
use Illuminate\Contracts\Events\Dispatcher;

return [
    (new Extend\Event())
        ->listen(Saving::class, function (Saving $event) {
            $minWordLimit = 5; // Change this to your desired minimum word limit

            $content = $event->post->content;

            // Remove HTML tags to get the plain text content
            $plainTextContent = strip_tags($content);

            // Split the plain text content into words
            $words = preg_split('/\s+/', $plainTextContent);

            // Exclude enforcement for administrator and moderator groups
            $user = $event->actor;
            if ($user instanceof User && ($user->isAdmin() || $user->isModerator())) {
                return;
            }

            if (count($words) < $minWordLimit) {
                $event->post->addError('content', 'Posts must have at least '.$minWordLimit.' words.');
                throw new InvalidPostException;
            }
        })
];

Only thing i'd like to change is the error even tho I try to force to Post must have... error it comes up with oops something is wrong error, need to look into why that is.
