adding admin attr authorize button cart code codes config create customer discount display due ejejc enable field form function html independent innerhtml jquery lines net note number order paypal phone postcall processed relevant request require screen settings text view

I'm not using PayPal, I'm using Authorize.net, and I'd like to be able to request a phone number from the customer before the order is processed.
Is this possible?

Unfortunately, with Authorize.net, there is no way to require a phone number from the customer before the order is processed.

Is there a way to at least request it, like with a text box or something? Or is this something I'd have to include in my html, independent of any e-junkie form?

If you won't ever be using discount codes, you could create a dummy Discount Code (Admin > Cart Discount Settings) to enable display of the Discount Code field in your cart, but then change the "Discount Code" text label in the cart screen by adding these lines to your View Cart button code, just before the "// -->" line:

function EJEJC_config() {
EJEJC_POSTCALL=true;
}
function EJEJC_shown() {
jQuery("#dscnt_cd").attr("innerHTML", "Your Phone Number");
}

NOTE: If EJEJC_config () {} already exists in your code due to other customizations, then simply add the relevant lines to it.
