Installation

The preferred way to install this extension is through composer.

Either run

composer require --prefer-dist mhndev/yii2-rate "0.0.*"

or add

"mhndev/yii2-rate": "0.0.*"

Configuration

create config file

then of all you need to create a configuration file in your yii2 project config directory called rate.php and fill it like following :

return [
    'userClass' => \app\models\User::class,
    'RateClass' => \mhndev\yii2Rate\Models\Rate::class,

    'items'=>[
        'post' => [
            'class'=> \app\models\Post::class,
            'rate_types' => ['rate','like'],
            'rate_values' => [
                'class' => \mhndev\rate\DiscreteNumberValue::class,
                'values' => ['1','2','3','4','5']
            ]
        ]
    ]
];

look at config array and check items field are entities which you want to rate them or like them. for example above config array has an item called post. and its fields are :

class

which specify entity class which you want to rate

rate_types

you can have multiple kind of rates for an entity for example a user can like a post entity and also rate it

rate_values

you can specify possible rate values for an entity

and after that your user class you should implement following interface

mhndev\rate\Interfaces\iUser

and add the following method for rate functionality persistence. you can change it as your project needs.

    /**
     * @param $value
     * @param iRateableEntity $entity
     * @param $type
     * @return Rate
     */
    public function doRate($value, iRateableEntity $entity, $type)
    {
        $rate = new Rate;

        $rate->type = $type;
        $rate->entity = get_class($entity);
        $rate->entity_id  = $entity->_id->__toString();
        $rate->owner = static::class;
        $rate->owner_id = Yii::$app->user->identity->id;
        $rate->value = $value;

        $rate->save();

        return $rate;
    }

Usage

Like

This is a sample code which uses this package :

    $post = Post::findOne(1);
    $user = Yii::$app->user->identity;
    $user->like($post);

Rate

    $post = Post::findOne(1);
    $user = Yii::$app->user->identity;
    $user->rate(+2, $post, 'rate');
