There are many reasons for using custom fields. Here’s one example.

Max Role Use Case: Suppose you want to limit the number of users that can be assigned to a particular role on your site. To accomplish this, you could create a max-users custom field for the role. Then, create logic to keep track and prevent more users from being added once the set limit was reached.

Adding a Custom Field

1. Open the Global Menu () and navigate to Control Panel → Custom Fields.

2. Click Role.

   

3. Click New to add a custom field.

4. For the above use case, select Input Field as the field type. Enter a Field Name and select Integer as the Data Type.

   

5. Click Save

Note

The Field Name is the identifier stored in your database and the name that is used by the developer to access the custom field.

After creating a custom field, you can find it in the UI of the resource you created it for. In this case, the max-users custom field is now visible for all roles.

1. Open the Global Menu () and navigate to Control Panel → Roles.

2. Select a role or click Actions () → Edit.

   

   Notice the Max Users field at the bottom.

Editing Custom Fields

To edit a custom field, click Actions () next to a custom field and click Edit. These options appear:

• Edit: You can change different aspects of the custom field except its name and type. The configuration options you have depend on the field type you choose.

• Permissions: You can modify the permissions to allow other users to edit or view a custom field.

• Delete: You can delete the custom field.

Field Types

There are several different field types you can choose.

  • Text Area: This field type can collect longer lines of text.

  • Input Field: This field type can collect a string of text, a decimal number, or an integer.
