Advanced Custom Fields – Required Field add-on


This Add-on has been Deprecated

The functionality provided by this add-on is now included in Advanced Custom Fields.
This plugin will no longer be maintained and it is recommended that everyone discontinue its use.

This is an add-on for the Advanced Custom Fields
WordPress plugin and will not provide any functionality to WordPress unless Advanced Custom Fields is installed
and activated.

The required field provides the ability to create fields that must be filled out before a post can be published.
Required field is a wrapper for other field types, meaning that you can use this field with any other field in
Advanced Custom Fields to make it required. Some complex field types may not function properly if marked as
required (required field may think it has content when it really does not).

The Required Field plugin can be used as WordPress plugin or included in other plugins or themes.

Make sure you have Advanced Custom Fields installed and
