Laravel Likeable Plugin

NOT STABLE

Trait for Laravel Eloquent models to allow easy implementation of a "like" or "favorite" or "remember" feature.

Composer Install

"require": {
    "cloud9business/eloquent-likeable": "0.1.*"
}

Run the migrations

php artisan migrate --package=cloud9business/eloquent-likeable

Setup your models

class Article extends \Eloquent {
    use Cloud9Business\EloquentlLikeable\LikeableTrait;
}

Sample Usage

$article->like(); // like the article for current user
$article->like($myUserId); // pass in your own user id
$article->like(0); // just add likes to the count, and don't track by user

$article->unlike(); // remove like from the article
$article->unlike($myUserId); // pass in your own user id
$article->unlike(0); // remove likes from the count -- does not check for user

$article->likes; // get count of likes

$article->liked(); // check if currently logged in user liked the article
$article->liked($myUserId);

Article::whereLiked($myUserId) // find only articles where user liked them
	->with('likeCounter') // highly suggested to allow eager load
	->get();

Likeable Controller

Also this package provides \Cloud9Business\EloquentlLikeable\LikeableController, which handle requests to like entities

Usage

Add the service provider to app/config/app.php

'providers' => array(
    // providers...
    
    'Cloud9Business\EloquentlLikeable\LikeableServiceProvider',
)

publish the config:

php artisan config:publish cloud9business/eloquent-likeable

Add models you need to sort in the config app/config/packages/cloud9business/eloquentl-likeable/config.php:

'entities' => array(
     'articles' => '\Article', // entityNameForUseInRequest => ModelName
),

Add route to the like method of the controller:

Route::post('like', '\Cloud9Business\EloquentlLikeable\LikeableController@like'); 

Now if you post to this route valid data:

$validator = \Validator::make(\Input::all(), array(
    'type' => array('required', 'in:like,unlike'), // type of like, like or unlike
    'entityName' => array('required', 'in:' . implode(',', array_keys($likeableEntities))), // entity name, 'articles' in this example
    'id' => 'required|numeric', // entity id
));

Then entity with \Input::get('id') id will be liked or unliked as specified.

For example, if request data is:

type:unlike
entityName:articles
id:3

then the article with id 3 will be unliked.
