Simple extension for assigning a group based on number of posts?

LiamKenyon i have not tested this, so I don't know if it works

    (new Extend\Event)
        // Add a user to a specific group after number of approved posts, requires flarum/approval.
        ->listen(\Flarum\Post\Event\Posted::class, function (\Flarum\Post\Event\Posted $event) {
            // map post requirement => group id
            $thresholds = [
                30  => 5,
                150 => 7
            ];

            $groups = $event->post->user->groups ?? \Illuminate\Support\Collection::make();

            // Filter admin and moderator
            if ($groups->whereIn('id', [
                \Flarum\Group\Group::ADMINISTRATOR_ID,
                \Flarum\Group\Group::MODERATOR_ID,
                // Add more Group Ids here to exclude them from the check
            ])->isNotEmpty()) {
                return;
            }

            // Get user post count
            $postCount = $event->post->user->comment_count ?? 0;

            // we need to loop backwards to see if they match the highest threshold, we apply
            // that group first

            foreach (array_reverse($thresholds) as $requiredCount => $groupId) {
                // If the user meets the requirement
                if ($postCount >= $requiredCount) {
                    // get the removable group ids
                    $removableGroupIds = \Illuminate\Support\Arr::except(array_values($thresholds), $groupId);

                    $event->post->user->getConnection()->transaction(function () use ($event, $groupId, $removableGroupIds) {
                        // add the group
                        $event->post->user->groups()->attach($groupId);
                        // remove the other groups
                        $event->post->user->groups()->detach($removableGroupIds);
                    });
                }

            }
        }),

luceos I did try this and it broke the forum

I'm assuming I edit \Flarum\Group\Group::ADMINISTRATOR_ID to the number or is this stay the name of the group?

I'm current using the above and testing atm.

    (new Extend\Event)
        // Add a user to a specific group after number of approved posts, requires flarum/approval.
        ->listen(\Flarum\Post\Event\Posted::class, function (\Flarum\Post\Event\Posted $event) {
            $needsApprovedPosts1 = XX; // number of approved posts to add group1 to user
            $needsApprovedPosts2 = XXX; // number of approved posts to add group2 to user
            
            $addGroup1 = X; // use the Id of the group1 you want to add
            $addGroup2 = X; // use the Id of the group2 you want to add
            
            $adminGroup = X;
            $modGroup = X;
            $contGroup = X;
            $donGroup = X;

            $user = $event->post->user;
            // Skip if user is already part of group
            if ($user->groups->find($addGroup1) !== null) return;
            if ($user->groups->find($addGroup2) !== null) return;
            
            if ($user->groups->find($adminGroup) !== null) return;
            if ($user->groups->find($modGroup) !== null) return;
            if ($user->groups->find($contGroup) !== null) return;
            if ($user->groups->find($donGroup) !== null) return;
            
            $postCount = $user->posts()
                              ->where('is_approved', 1)
                              ->whereNull('hidden_at')
                              ->count();
             
            if ($postCount >= $needsApprovedPosts1 && $postCount < $needsApprovedPosts2) {
                $user->groups()->attach($addGroup1);
            } elseif ($postCount >= $needsApprovedPosts2) {
                $user->groups()->detach($addGroup1);
                $user->groups()->attach($addGroup2);
            }
        }),
