Question

How do I put a limit on one of the rows in an Eloquent result?

Scenario

I need to retrieve only around 100 characters from one of the fields in my result. Currently I'm using a join statement so multiple results are being returned. I basically need only the first 100 characters from post.content

Code

public function getAll()
    {
        return Post::select('posts.id', 'posts.title', 'posts.content', 'posts.views', 'posts.comments', 'posts.tags', 'posts.date_created', 'users.image_url', 'users.username', 'users.toxick')
                    ->join('users', 'posts.user_id', '=', 'users.id')
                    ->get();
    }

I'm not sure how to go about putting a filter on the query to only return 100 characters. I've looked around briefly but I've not found anything useful, not to my specific scenario at least.

Cant test this at the moment (sorry) but what about:

public function getAll(){
    $query = Post::select('posts.id', 'posts.title', 'posts.content','posts.views', 'posts.comments', 'posts.tags', 'posts.date_created', 'users.image_url', 'users.username', 'users.toxick')
                ->join('users', 'posts.user_id', '=', 'users.id')
                ->get();

    foreach($query as $entries){
        $entries->content = substr($entries->content, 1, 100);
    }

    return $query;
}
