Laravel Likeable is a package designed to add like and dislike functionality to your Laravel applications. It allows users to easily express their opinions on content (such as posts, comments, or any other models) by liking or disliking them, enhancing user engagement on your platform.

Key Features

Easy Integration: Simple setup to add like/dislike functionality to your Eloquent models.
Flexible: Can be used with various models, such as posts, comments, or any custom model.

User-Friendly: Allows users to like or dislike content with ease, improving interaction.

Installation

To install Laravel Likeable, you can use Composer. Run the following command in your terminal:

bash

composer require "kordy/laravel-likeable"

1	composer require "kordy/laravel-likeable"

Configuration

After installing the package, you need to publish the configuration file and migrations:

bash

php artisan vendor:publish --provider="Kordy\Likeable\LikeableServiceProvider"

1	php artisan vendor:publish --provider="Kordy\Likeable\LikeableServiceProvider"

This will create the necessary configuration file and migration files.

Migration

Run the migrations to create the likes table in your database:

bash

php artisan migrate

1	php artisan migrate

Setting Up Your Model

To enable likeable functionality in your model, you need to use the Likeable trait. For example, if you want to add like functionality to a Post model, your model should look like this:

php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Kordy\Likeable\Likeable;

class Post extends Model
{
    use Likeable;

    // Your model properties and methods here
}

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

use Kordy\Likeable\Likeable;

class Post extends Model

{

use Likeable;

// Your model properties and methods here

}

Liking and Disliking

With Laravel Likeable, you can easily implement the like and dislike functionality in your controllers or routes.

Liking a Post

You can like a post using the like method:

php

$post = Post::find($postId);
$post->like($userId); // Like the post

1 2	$post = Post::find($postId); $post->like($userId); // Like the post

Disliking a Post

Similarly, you can dislike a post:

php

$post->dislike($userId); // Dislike the post

1	$post->dislike($userId); // Dislike the post

Removing a Like or Dislike

To remove a like or dislike from a post, you can use the unlike or undislike methods:

php

$post->unlike($userId); // Remove like
$post->undislike($userId); // Remove dislike

1 2	$post->unlike($userId); // Remove like $post->undislike($userId); // Remove dislike

Checking Likes and Dislikes

You can check if a user has liked or disliked a post:

php

if ($post->isLikedBy($userId)) {
    // User has liked the post
}

if ($post->isDislikedBy($userId)) {
    // User has disliked the post
}

if ($post->isLikedBy($userId)) {

// User has liked the post

}

if ($post->isDislikedBy($userId)) {

// User has disliked the post

}

Retrieving Likes and Dislikes

You can retrieve the total number of likes and dislikes for a post:

php

$totalLikes = $post->likes()->count();
$totalDislikes = $post->dislikes()->count();

1 2	$totalLikes = $post->likes()->count(); $totalDislikes = $post->dislikes()->count();

Example Usage

Here’s a simple example of how you might implement liking functionality in a controller method:

php

namespace App\Http\Controllers;

use App\Models\Post;
use Illuminate\Http\Request;

class PostController extends Controller
{
    public function like(Request $request, $id)
    {
        $post = Post::findOrFail($id);
        $post->like($request->user()->id);

        return response()->json(['message' => 'Post liked successfully!', 'likes' => $post->likes()->count()]);
    }

    public function dislike(Request $request, $id)
    {
        $post = Post::findOrFail($id);
        $post->dislike($request->user()->id);

        return response()->json(['message' => 'Post disliked successfully!', 'dislikes' => $post->dislikes()->count()]);
    }
}

namespace App\Http\Controllers;

use App\Models\Post;

use Illuminate\Http\Request;

class PostController extends Controller

{

public function like(Request $request, $id)

{

$post = Post::findOrFail($id);

$post->like($request->user()->id);

return response()->json(['message' => 'Post liked successfully!', 'likes' => $post->likes()->count()]);

}

public function dislike(Request $request, $id)

{

$post = Post::findOrFail($id);

$post->dislike($request->user()->id);

return response()->json(['message' => 'Post disliked successfully!', 'dislikes' => $post->dislikes()->count()]);

}
