Usage

Once the extension is installed, simply use it in your code by :

1. Add behavior,alias and validation rules to your model like this: ( you can use any alias it will be used to identify your $model::className in db if you will change alias, old attribute values will disappear =)) )

   public function behaviors() {

    return [
        [
            'class' => \mar\eav\behaviors\EavBehavior::className(),
            'modelAlias' => 'product',
            'eavAttributesList' => [
                'eavProperty1' => [
                    'rule' => [['eavProperty1'], 'string', 'max' => 255],
                    'type' => EavBehavior::ATTRIBUTE_TYPE_TEXT,
                ],
                'eavProperty2' => [
                    'rule' => [['eavProperty2'], 'integer'],
                    'type' => EavBehavior::ATTRIBUTE_TYPE_ARRAY,
                    // mode MODE_SET_EMPTY_IF_NO_VALUE_IN_REQUEST - clear attribute value if no value like Classname[attributeName] in request, usefull for forms handling
                    'modes' => [
                                                EavBehavior::MODE_SET_EMPTY_IF_NO_VALUE_IN_REQUEST
                    ]
                ],
                .....
            ]
        ]
   
    ];
   

   }

2. If you wish you can add labels for eav properties to attributeLabels() method of your model

3.That's all, you cat access your new property like $model->eavProperty1, also you can use it in form like this :

    <?= $form->field($model, 'eavProperty1')->textInput(['maxlength' => true]) ?>

PS: 1)attributes and values will be removed if you delete them from behavior config

possible future updates:

1. search by eav fields
2. relations by eav fields
3. using category_id to bind eav attributes to class by category
