👍 User like and dislike features for Laravel Application.
composer require abdulmananse/laravel-like-dislike
This step is optional
php artisan vendor:publish --provider="Abdulmananse\\LaravelLikeDislike\\LikeServiceProvider" --tag=config
This step is also optional, if you want to custom likes table, you can publish the migration files:
php artisan vendor:publish --provider="Abdulmananse\\LaravelLikeDislike\\LikeServiceProvider" --tag=migrations
use Illuminate\Foundation\Auth\User as Authenticatable;
use Abdulmananse\LaravelLikeDislike\Traits\Liker;
class User extends Authenticatable
{
use Liker;
<...>
}
use Illuminate\Database\Eloquent\Model;
use Abdulmananse\LaravelLikeDislike\Traits\Likeable;
class Post extends Model
{
use Likeable;
<...>
}
$user = User::find(1);
$post = Post::find(2);
$user->like($post);
$user->dislike($post);
$user->unlike($post);
$user->toggleLike($post);
$user->toggleDislike($post);
$user->hasLiked($post);
$user->hasDisliked($post);
$post->isLikedBy($user);
$post->isDislikedBy($user);
Get user likes with pagination:
$likes = $user->likes()->with('likeable')->paginate(20);
foreach ($likes as $like) {
$like->likeable; // App\Post instance
}
Get user dislikes with pagination:
$dislikes = $user->dislikes()->with('likeable')->paginate(20);
foreach ($dislikes as $dislike) {
$dislike->likeable; // App\Post instance
}
Get object likers:
foreach($post->likers as $user) {
// echo $user->name;
}
with pagination:
$likers = $post->likers()->paginate(20);
foreach($likers as $user) {
// echo $user->name;
}
Get object dislikers:
foreach($post->dislikers as $user) {
// echo $user->name;
}
with pagination:
$dislikers = $post->dislikers()->paginate(20);
foreach($dislikers as $user) {
// echo $user->name;
}
// all likes
$user->likes()->count();
// short way
$user->totalLikes;
// with type
$user->likes()->withType(Post::class)->count();
// all dislikes
$user->dislikes()->count();
// short way
$user->totalDislikes;
// with type
$user->dislikes()->withType(Post::class)->count();
// likers count
$post->likers()->count();
// short way
$post->totalLikers
// dislikers count
$post->dislikers()->count();
// short way
$post->totalDislikers
List with *_count
attribute:
// likes_count
$users = User::withCount('likes')->get();
foreach($users as $user) {
// $user->likes_count;
}
// dislikes_count
$users = User::withCount('dislikes')->get();
foreach($users as $user) {
// $user->dislikes_count;
}
// likers_count
$posts = Post::withCount('likers')->get();
foreach($posts as $post) {
// $post->likers_count;
}
// dislikers_count
$posts = Post::withCount('dislikers')->get();
foreach($posts as $post) {
// $post->dislikers_count;
}
To avoid the N+1 issue, you can use eager loading to reduce this operation to just 2 queries. When querying, you may specify which relationships should be eager loaded using the with
method:
// Liker
$users = User::with('likes')->get();
foreach($users as $user) {
$user->hasLiked($post);
}
// Disliker
$users = User::with('dislikes')->get();
foreach($users as $user) {
$user->hasDisliked($post);
}
// Likeable
$posts = App\Post::with('likes')->get();
// or
$posts = App\Post::with('likers')->get();
foreach($posts as $post) {
$post->isLikedBy($user);
}
// Dislike
$posts = Post::with('dislikes')->get();
// or
$posts = Post::with('dislikers')->get();
foreach($posts as $post) {
$post->isDislikedBy($user);
}
Of course we have a better solution, which can be found in the following section:
You can use Liker::attachLikeDislikeStatus($likeables)
to attach the user like status, it will attach has_liked
and has_disliked
attributes to each model of $likeables
:
$post = Post::find(1);
$post = $user->attachLikeDislikeStatus($post);
// result
[
"id" => 1
"title" => "Add socialite login support."
"has_liked" => true
"has_disliked" => false
],
$posts = Post::oldest('id')->get();
$posts = $user->attachLikeDislikeStatus($posts);
$posts = $posts->toArray();
// result
[
[
"id" => 1
"title" => "Post title1"
"has_liked" => true
"has_disliked" => false
],
[
"id" => 2
"title" => "Post title2"
"has_liked" => fasle
"has_disliked" => true
],
[
"id" => 3
"title" => "Post title3"
"has_liked" => true
"has_disliked" => false
],
]
$posts = Post::paginate(20);
$user->attachLikeDislikeStatus($posts);
