    While doing research we came across the question " How to test for a boolean field in a twig template? I also wouldn't recommend to use type safe checks with content entities because they are not type safe. Values are stored in the database and anything coming out from there is a string but sometimes values might not be. The boolean field is actually the perfect example for that, it is a string one, aka a nice mix of 3 different data types. For me, one test did not work consistently.

    However, the following condition seems to have covered all the use cases. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Podcast Programming tutorials can be a real drag. Featured on Meta. Community and Moderator guidelines for escalating issues via new response….When we build Drupal websites, we often have to create a custom data structure which can hold multiple values, each value having its own set of fields.

    For example, a phone number might have a country code, area code, the actual number, and then a type work, home, cell. And you might have to create a field that accepts multiple phone numbers. You might be tempted to build out these types of fields using a module like field collections or paragraphs, but if you're a Drupal developer, you can easily create custom reusable fields to accomplish the same thing.

    The Drupal 8 Field API gives us a pretty straight-forward way to do this in a custom module, and the result is a field that we can easily re-use across content types. In this blog post, I'll show you how to create a custom compound field for Drupal 8, using burrito ingredients as the example. Creating our field will involve three main steps:. Reading this post should give you a basic idea as to how to do the three tasks listed above and adapt the example provided to build your own shiny new custom field!

    So I thought, what if we had a site where visitors could write articles and with each article, they could include the set of ingredients they prefer in their burritos? Every user would be able to create a piece of content node specifying multiple burrito recipes, each recipe having:.

    It includes the following important files:. Unlike Drupal 7, field types, field widgets and field formatters are defined and detected using Plugin definitions with annotations like FieldTypeFieldWidget and FieldFormatter respectively. Instead, there are separate files to define our plugins.

    These are used for organizing code and for autoloading classes in Drupal 8. The first thing to do is create a FieldType plugin implementation. This is done using a class which represents a single item of the Burrito field type. By convention, it has been named the BurritoItem. However, it is good practice to define stuff in the namespace of your own module.

    Here's a quick look at what we defined:. Here, we define storage columns to be created in the database table for storing each value of the given field type.

    After a user enters values into your custom field and hits submitDrupal checks to see if the fields are empty. If they are empty, it doesn't try to validate or save anything. Hence, the sole purpose of this isEmpty method is to help Drupal understand when a field item should be considered empty and hence ignored. In the example below, I check if the user has entered anything in the text boxes or checked any of the checkboxes - if yes, then we treat the BurritoItem as non-empty by returning FALSE.

    After you define the field type, you can enable the Burrito Maker module and you'll be able to see your field type on the Add field screen. Custom field type visible in field type selection. This is because we have not defined the field widget and field formatters yet. Though we could have defined all the three classes first and then enabled the module, I personally like to see visible evidence of progress like clients when I code. Seeing my custom field in the list of field types gets me motivated me to write the rest of the classes.

    So, the database tables are ready and your field type appears in the UI. But how would the user enter data for their custom burritos?

    Drupal doesn't know anything about them burritos! So, we need to implement a FieldWidget plugin to tell Drupal exactly how it should build forms for accepting burrito data.

    To define the structure of the widget, we create the following class with the FieldWidget annotation:. This class must implement the required method formElement.

    However, in our example, we have two other utility methods as well.We can get value at node. Body The default body field on a content type is essentially a Text formatted, long, with summary field type. Content display :.

    Display whatever is set up in Manage Display. If the body field is set to Summary or Trimmed, this will show that. Content value, formatted :. Shows the content of the text field itself, regardless of what is set in Manage Display.

    This will parse any HTML. Content value, unparsed HTML :. Text plain and Text plain, long Content display :. Text formattedText formatted, longText formatted, long, with summary Content display :. Again, this shows whatever is set up in Manage Display, which could be Default or Trimmed. List List floatList integerList text These are fields with a key and label.

    The key is what is stored as the value.

    If the Display is set to Key, it will show key. So you might want to do this by changing the Manage Display to Label. Content key :. These will show the first item in the field. For multi-value fields you can show a different item by changing the 0 to another number.

    Remember start counting at 0; the second item would be 1. Boolean This works very much like List, but the key works a little differently.
