It provides a number of methods that make it easy to query entities based on conditions such as field values or class properties. In this article I am going to talk about what we have in Drupal 8 for querying entities.

As mentioned, there are two ways we can access the entity. Statically, we can do this:. Alternatively and the highly recommended approach is to use dependency injection.

If you have access to the container, you can load the service from there and then get the right query object:. As you can see, there is no more distinction between propertyCondition and fieldCondition as there is in D7 with EntityFieldQuery. Additionally, we can include conditions based on referenced entities tacking on the entity.

An important thing to note is that we also have the langcode parameter in the condition method by which we can specify what translation of the node should be included in the query. For instance, we can retrieve node IDs that contain a specific value inside of a field in one language but another value inside the same field for another language. For more information on the condition method you should consult the API documentation. The next thing we are going to look at is using condition groups both AND and OR for more powerful queries:.

And we did so by creating an orConditionGroup object that we then pass to the query as a condition. And we can group together multiple conditions within a andConditionGroup as well. There are many other methods on the QueryInterface that can extend the query such as for sorting, range, etc.

I encourage you to check them out in the documentation and experiment with them.

In Drupal 8, this helper function is maintained and you can use it pretty much in the same way, except only for one entity at a time:. And the return value is a node object. A bonus nugget of information is that both of these functions are wrappers for the storage manager of the entities in question.

They basically retrieve the storage manager statically and then call the load and loadMultiple methods, respectively, on it:. But better yet, you could use dependency injection and retrieve the storage class from the container:. And then proceed with the loading.

This makes it easier to test your class and better decouples it from the rest of the application. There has been an overhaul of the D7 EntityFieldQuery class that turned into a robust API for querying both content and configuration entities.
