Invitation Codes: Gravityforms Add-on

This plugin is created to enable WordPress site owners to specify a custom invitation code to be used with Gravity Forms. Once an invitation code is specified on a form, the user can’t submit that form until that invitation code is entered in the field during the form submission. This plugin can be combined with the Gravity Forms User Registration Add-On to make sure that only people with a correct invitation code can register on your website.

1. 01Upload the plugin folder to your /wp-content/plugins/ folder.
2. 02Go to the Plugins page and activate the plugin.
3. 03Create a GravityForm form and go the edit page.
4. 04Within the Advanced Fields section in the editor, select “Invitation Code”.
5. 05In the General tab of the Field Settings fill in the Invitation Code you want.
6. 06In the Appearance tab of the Field Settings, you can specify the “Custom Validation Message”. This message will be shown to the user when a wrong invitation code is submitted.
