Are there "global" notification variables

There aren't global variables, every form is unique. However, if you are using WordPress Multi-Site you can pre-generate forms (and the license key) so that you don't have to do it every single time you create a site. It will automatically create the forms for you when you activate a new site in multi-site.

To automatically create forms when a new site is activated in Multi-Site you need to first create your initial forms that you want to replicate. Then you use the Import/Export tool and select Export Forms, select the forms you want to export (these are the forms you want to automatically create) and then export them to an XML file.

Place the XML file somewhere on your web server, such as your wp-content/uploads folder or somewhere easily accessible and then add this to your wp-config.php file:

define(“GF_IMPORT_FILE”, “http://www.domain.com/path/to/gf_import.xml”);

After doing this, when you activate a new site in WordPress Multi-Site this XML import will get executed and the forms will be created on the site that you are activating. This only happens on new activations, not existing sites.

If you want to pre-populate your Gravity Forms license key when activating a new site in WordPress Multi-Site you can add this to your wp-config.php file:

define(‘GF_LICENSE_KEY’,'YOUR_KEY_GOES_HERE’);

This will then pre-populate your key anytime you activate a new site.
