Ubercart

While the customer fills out the checkout form, all of the updates are necessarily done in JavaScript so that we can keep a one-page checkout. However, once the "Review Order" button is clicked, all the values are recalculated by the server, so all the values displayed on the review page are as accurate and secure as they can be.

The shipping quotes and payment forms are still served by JavaScript, and I doubt that is going to change. Google Analytics says that over 99% of our stores' users have JavaScript enabled, and we figure that the few that don't will at least know how to enable it again to use our sites.

If the checkout is not going to degrade gracefully from not having javascript support, then shouldn't there be a message given stating that javascript is required and maybe how to enable javascript. Though, I would like to see the checkout process not require javascript. I'd rather not let any potential buyer slip through the cracks.

This would be a good candidate to start out as a contributed module or something... I don't know exactly how you'd want it to work, but it seems like you can add the message to the top of the checkout form and hide it using JS.

I was thinking something more along the lines of the checkout process starts via an O.K. from javascript, thus printing the checkout screen. If the javascript does not return the O.K., namely javascript is disable, then a message is supplied. I don't know that this would be too hard, though there are probably a couple of different ways to pull this off.

Google Analytics records information via JavaScript so if a user does not have JavaScript enabled, then no information is going to be recorded.

If you want to track if users have javascript enabled, you will have to gather your site's stats via something else that doesn't require javascript.

Does this mean if I have an ubercart shop with any sort of shipping costs applied users unable to use javascript cannot purchase anything through my shop?

Unfortunately there are disability discrimination laws in my country which make this slightly more than an inconvenience. Providing a shop that can't be accessed over a screen reader (i.e. usually without javascript) is a good way to get sued.

Have I missed some option that allows me to have a multipage form or automatically generate a shipping quote on the confirmation page?

Added a patch for uc_quote which gives a non-javascript alternative to the shipping quote javascript element (solves my problem anyway, might be of use to someone else)

You might also consider the fact that the payment details that come up in checkout are AJAXed in, too. We have plans to work on this in the D6 cycle, but it will stay like it is for D5.

Aha.

The shop I'm working on only allows the one payment method and it's a "redirect to a different site" kind so it's bypassed any of the AJAX stuff there.

Thanks for the tip though - something to bear in mind for the next one if it's more integrated.

What is the current word on this in the D6 cycle?

I just ran headlong into this problem yesterday -- the user was very upset and was unaware that he had Javascript disabled (thanks to IE's convoluted security settings).

My kludgy solution is to put the following HTML in the checkout instructions (admin/store/settings/checkout/edit/messages):

Hi guys,

just wondering if we can integrate a seperate ubercart payment area for mobile phones ?

The issue is the iPhone doesn't seem to support javascript so there is no way to execute a sale via mobile.

Perhaps an sms payment gateway ?
