Entities objects are loaded using the entity type manager service (technically, the entity storage manager). Field values are read from the entity object. Doing this, instead of directly accessing data in the database, ensures that our custom code can remain agnostic about any underlying data storage logic. Reading field values is a common task, and we'll practice it by loading a vendor entity and using existing field values to pre-populate the new vendor attendance form.
In this tutorial, we'll:
- Load an entity using the entity type manager service.
- Access raw values of entity fields.
- Use
#default_valuein Form API to pre-populate form fields.
By the end of this tutorial, you'll be able to get raw field values from entities.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
