Make a field required

The required validation rule checks that a field contains a value. The field must contain a value for the entry to be published.

With a content type open for editing:

1. Select the field you want to set a validation rule for and select the Validation tab from the Field Settings panel.
2. Change the Required field toggle to Yes to make the field required.
3. An alternative validation message can be added by entering it in the Validation message text box. This will be displayed if the field fails validation when published.
