I have a Ninja form with textbox fields for user_firstname, user_lastname, and website. When someone submits the form, where does the data go in the WordPress database? Suppose, for example, I want to know the website for a given user_firstname and user_lastname. So I want something like:
sql = "SELECT 'website' from ??? WHERE user_firstname = 'John' AND user_lastname = 'Allen'";
What is the table I need to access?
