I need this query string because it is a unique ID. This unique ID is used to populate DIFFERENT values dynamically into the form's fields.</p> <p>For example, lets say I invoke my form: <a href="http://www.foo.com/form/?ID=1" rel="nofollow">http://www.foo.com/form/?ID=1</a> ID=1 means that this form pertains to the state of CA. Lets say I have a dropdown of zip codes that I want to dynamically populate with only CA zip codes.</p> <p>As I understand it, I must use the hook, gform_pre_render() to populate dropdowns. However, at this function, I don't see my ID field dynamically populated with the value, 1, so I can't determine what zip codes to fill in my ZIP dropdown.</p> <p>Any ideas? </p>
