Video Tutorial

Installation

Download package into the project using Composer.

composer require qirolab/laravel-reactions

Registering package

Laravel 5.5 (or higher) uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider.

For Laravel 5.4 or earlier releases version include the service provider within app/config/app.php:

'providers' => [
    Qirolab\Laravel\Reactions\ReactionsServiceProvider::class,
],

Database Migration

If you want to make changes in migrations, publish them to your application first.

php artisan vendor:publish --provider="Qirolab\Laravel\Reactions\ReactionsServiceProvider" --tag=migrations

Run database migrations.

php artisan migrate

Config File

You can optionally publish the config file with:

php artisan vendor:publish --provider="Qirolab\Laravel\Reactions\ReactionsServiceProvider" --tag="config"

Usage

Prepare Reacts (User) Model

Use Qirolab\Laravel\Reactions\Contracts\ReactsInterface contract in model which will perform react behavior on reactable model and implement it and use Qirolab\Laravel\Reactions\Traits\Reacts trait.

use Qirolab\Laravel\Reactions\Traits\Reacts;
use Qirolab\Laravel\Reactions\Contracts\ReactsInterface;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements ReactsInterface
{
    use Reacts;
}

Prepare Reactable Model

Use Qirolab\Laravel\Reactions\Contracts\ReactableInterface contract in model which will get reaction behavior and implement it and use Qirolab\Laravel\Reactions\Traits\Reactable trait.

use Illuminate\Database\Eloquent\Model;
use Qirolab\Laravel\Reactions\Traits\Reactable;
use Qirolab\Laravel\Reactions\Contracts\ReactableInterface;

class Article extends Model implements ReactableInterface
{
    use Reactable;
}

Available Methods

Reaction

$user->reactTo($article, 'like');

$article->react('like'); // current login user
$article->react('like', $user);

Remove Reaction

Removing reaction of user from reactable model.

$user->removeReactionFrom($article);

$article->removeReaction(); // current login user
$article->removeReaction($user);

Toggle Reaction

The toggle reaction method will add a reaction to the model if the user has not reacted. If a user has already reacted, then it will replace the previous reaction with a new reaction. For example, if the user has reacted 'like' on the model. Now on toggles reaction to 'dislike' then it will remove the 'like' and stores the 'dislike' reaction.

If a user has reacted like then on toggle reaction with like. It will remove the reaction.

$user->toggleReactionOn($article, 'like');

$article->toggleReaction('like'); // current login user
$article->toggleReaction('like', $user);

Boolean check if user reacted on model

$user->isReactedOn($article));

$article->is_reacted; // current login user
$article->isReactBy(); // current login user
$article->isReactBy($user);

Reaction summary on model

$article->reactionSummary();
$article->reaction_summary;

// example
$article->reaction_summary->toArray();
// output
/*
[
    "like" => 5,
    "dislike" => 2,
    "clap" => 4,
    "hooray" => 1
]
*/

Get collection of users who reacted on model

$article->reactionsBy();

Scopes

Find all articles reacted by user.

Article::whereReactedBy()->get(); // current login user

Article::whereReactedBy($user)->get();
Article::whereReactedBy($user->id)->get();

Reaction on Model

// It will return the Reaction object that is reacted by given user.
$article->reacted($user);
$article->reacted(); // current login user
$article->reacted; // current login user

$user->reactedOn($article);
