Gravity Forms Janrain Add-on

FAQ

I can’t find (Facebook/Twitter/other provider) in the list of available
providers.

Some providers require configuration in order to be available. To use Facebook
login through Janrain Engage, for example, you will have to create an app on
Facebook, and give those credentials to your Engage app.

Luckily, there are current step-by-step directions on the Engage dashboard. Go
to the “Setup Widget” page on your Janrain dashboard (find it under
Deployment > Sign-in for Web; open the Providers section of the
sidebar). Each of the providers which requires configuration will have a gray
gear icon next to it; click that icon and follow the wizard steps.

I want to be able to access a field that a provider offers, but it’s not
populating in my forms.

Some profile fields require requesting extended profile data. You can configure
the permissions your app requests of the user on an “a la carte” basis from your
rpxnow dashboard under Deployment > Provider Configuration. (Keep in mind
that asking users for too many permissions is more likely to scare them away –
don’t be a creeper!

NOTE: some extended profile fields are only available to Plus or higher
service levels.

How can I add more prefill fields beyond the default ones?

This plugin has been designed to be easy to extend. If you want to add more
fields, you will need to hook a function to the filter janrain_gforms_profile_data
that defines the name of the field you want to add, and the function to get its
data. This filter recieves the array of core fields as its argument, so if you
need to redefine one of the core fields, this is the place to do that as well.

For example, the following code will make a new field available called
“religion”; which pulls any data the user has entered as their “religion” on
Facebook (or any other provider that includes that field):

add_filter( 'janrain_gforms_profile_data', 'add_religion_field' );

function add_religion_field( $fields ) {
    $fields['religion'] = array(
        'name' => 'Religion',
        'function' => 'religion_field'
    );
    return $fields;
}

function religion_field( $profile ) {
    return $profile->merged_poco->religion;
}
