Adding security message

Just replied to your email about this, but I’ll leave my response here too in case it benefits others:

You can achieve what you want with a little bit of custom code. Here is a snippet of code you can use as a starting point: https://github.com/Charitable/library/blob/master/extensions/ambassadors/campaign-submission-form/add-description-field.php

You’ll need to change this line:

add_filter( 'charitable_campaign_submission_campaign_fields', 'ed_add_description_field_to_form' );

Change it to:

add_filter( 'charitable_credit_card_fields', 'ed_add_description_field_to_form' );

See https://github.com/Charitable/library#how-to-use-the-code-snippets for tips on how to add this to your site.

Cheers,
Eric
