Yii2 - left join on multiple condition

Question

I have three tables with the following relations,

  ------- 1        0..* ------------
 |Product|-------------|Availability|
  -------               --------         


        

Answer 1

Just use like below condition.

$query = Product::find()
 -> leftJoin('availability', 'availability.productID=product.ID  AND a.start>=DATE_ADD(DATE(now()), INTERVAL 7 DAY)')
 ->leftJoin('meta_data', 'meta_data.ID=product.meta_dataID')
 ->where(['is', 'availability.ID', NULL])
 ->andWhere(['=', 'meta_data.published_state', 1])
 ->all();
