How to Set Permissions for Fields in Drupal 8

Define Role Based Field Permissions in Drupal 8

The Field Permissions module in Drupal 8 allows you to set permissions (enter, edit or view) on a Drupal field, based on the role the user belongs to.

In order to demonstrate how this module works, we are going to create a content type called “Essay” for the website of a school.

There will be 2 roles:

  • Freshman
  • Sophomore.

The Freshmen permission will not be allowed to choose the subject of the essay, whereas the Sophomores will have the possibility to choose between literature and history. However, there will be no possibility to change the subject once a student has made a choice.

Let’s start!

Step #1. Install the required modules

There are many ways to install a Drupal module. One of them is to use Composer.

  • Type into your terminal application:

composer require drupal/field_permissions

  • Click Extend.
  • Scroll down until you find the Field Permissions module and mark the checkbox.
  • Click Install.

Step #2. Create the Roles

  • Click People.
  • Click the Roles tab.
  • Click Add role in order to add the Freshman role.

  • Enter the role name.
  • Click Save.

  • Repeat the process for the Sophomore role.

Step #3. Create the Users

You have to create two users, one for the Freshman role and one for the Sophomore role

  • Click People > Add User.
  • Create a user and check the Freshman box.
  • Click Create new account.

  • Repeat the process for the Sophomore role.

  • Click the Permissions tab.
  • Mark the following permissions for both roles you just created:
    • Essay: Create new content
    • Essay: Edit own content (students are able to change their essays, however, they will not be able to change the subject choice once they save the form the first time)
    • Access the content overview page
    • Use the administration pages and help
    • Use the Toolbar
  • Click Save permissions.

Step #4. Create the Essay Content Type

The Essay content type will have only two fields:

  • Body
  • Subject choice.

The field Subject choice will be only available to the Sophomore role, however, once a student has made a choice, they won’t be able to change it anymore.

  • Click Content > Content types > Add content type.
  • Add a proper Name and leave the default values.
  • Click Save and manage fields.

  • Click Add field.
  • Select List (text) as the field type.
  • Click Save and continue.

  • Enter the two possible values in the Allowed values list.
  • Leave the default allowed number of values (1).
  • Click Save field settings.
  • Mark this field as required.
  • Check the Custom permissions radio button.

Sophomores will be able to enter a value for this field, to view it and to view the subject choice of other sophomore students. Freshmen will only be able to view the choice of their elder classmates.

  • Mark the corresponding checkboxes.
  • Click Save settings.

Step # 5. – Create Content

  • Log out from the site and log back in as a Sophomore.

  • Click Content > Add content.
  • Enter a proper body.
  • Choose one of the two available subjects.
  • Click Save.

You can now see the node. Let’s suppose the student wants to change the content of her essay.

  • Click the Edit tab.

You will see that the subject choice field is not available anymore.

  • Log out and log back in as a Freshman student.
  • Click Content > Add content.
  • Enter a proper body.
  • Click Save.

As you can see, this role does not have the possibility to make a subject choice. If you go back to the homepage of your Drupal installation, you will see both teasers.

  • Click the “Sophomore” essay.

The Freshman student is able to view the subject choice of his sophomore classmates.

I hope you liked this tutorial and it will help you improve your site building skills. The Drupal 8 Field Permissions module works not only with nodes but with other entities like users too.
