Drupal 8 entity query entity reference condition

Often when building a site in Drupal you'll find yourself wanting to display a list of nodes, or find entities created by a particular author, or locate some content based on a particular set of criteria.

Rather than querying the database directly, Drupal provides a helper class, EntityQueryto make things a bit easier. The EntityQuery class and entity. In this tutorial we'll go through several examples of using EntityQuery to find subsets of content. By the end of this article, you should understand how to use entity queries to create custom sets of data from entities.

The most important method in the EntityQuery class is the condition method. Conditions allow us to limit our query in specific ways so that we can get back exactly what we want.

Let's walk through a few examples in code to get a sense of how this can work in practice. The condition method takes up to four arguments: field, value, operator, and language code. The field should be the field name and optional column of the field being queried. Column names can be useful when dealing with reference fields, since additional field names can then be chained together.

An example of this chaining would be if you want to query for articles created by a particular user name rather than by ID you could use.

Once you have the field name and the desired value identified, the next parameter passed to the condition method is the operator.

For most operators, the value and the type of the column need to be the same literal. The final parameter is language code. Perhaps unsurprisingly, this allows you to limit the results of a query based on the translation status in a particular language. Two other methods that come in handy when building up the conditions of a query, orConditionGroup and andConditionGroup.

Either allows you to define a group of conditions which will subsequently be either OR'ed or AND'ed together. If you need a simple check whether or not a particular field exists you can use the exists or notExists methods. The sort method can be useful to order the results returned from EntityQuery in a particular way.

If you're less interested in the actual entity ids, and more interested in how many entities match a particular query the count method returns the number of entities found matching your conditions. Especially when working with a site that has a large amount of content it's important to think about limiting the number of results your query might return.

Imagine the amount of memory required to load all of the published issue queue nodes from drupal.

That wouldn't be a very smart idea. This is where the pager and range methods come in handy. Pager allows us to specify a particular number of results, while the range method allows us to specify an index or starting number and the length or page size or results to return. Together these can be used to return a subset of any size from a result set. See the blog post at Evolving Web.

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. Supposedly we now have to load those entity objects and work with them.

How do we do that? 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. And that is a bit of a win for the new Drupal 8 entity system. Next up, we are going to look at defining our own content entity type in Drupal 8.

I'm just putting in a random field. The only thing I care about is getting an orConditionGroup to work, the specifics of the other fields don't matter to me, they're just example placeholders. You could replace status with any other random field and my question is the same. I'll update my question for clarity. Without knowing the goal it's hard to point out where the problem is.

Is that right or wrong?

It only takes a minute to sign up. I have a content type that has a entity reference field that allows users to add multiple taxonomy terms in that field.

I'm attempting to perform queries that grab nodes that have a specific set of taxonomy terms within that field. Where 2 is the id of the term I'm searching for. However when I attempt to search for nodes that contain two specific terms like so. Which doesn't fail, but doesn't provide the intended results.

It displays every node that has either term 2 OR term 8. Instead of term 2 AND term 8 as intended.
